You always dreamed to be the hero of the village since young. Now it's time for you to shine. Prepare for all kinds of adventures, monsters, traps, you will encounter. All that you know is that this is hard, but you know that *`with great power comes great responsibility`*. So you must go on and defend your village. Be the hero. Wish you good luck!\n\n(*Note: you must go before the dark as nearby monsters attack your village at night.*)\n\n\n# Prerequisites\n\nYou are given *`at most a 5*5 map`* since your village don't have a lot of paper to make you a map.\n\nFor Example: \n\n![village_perspective](village_perspective.JPG)\n\n1. Your default stats (Player)\n+ Blood: 10\n+ Strength: 2\n+ Hunger: 20\n+ Coins: 10 \n+ Level: 1\n\n2. Your village's default stats\n+ Blood: 50\n+ Strength: 0 \n+ Level: 1\n\n## If your strength / hunger / coins = 0\nIf you don't have enough hunger or strength the next time you lose either of them you will lose blood. But if you don't have enough coins (coins = 0), your coins will just be 0 if you lose them next time.\n\n# How to play / Rules\n\nYou start from day 1 of defending the village.\nWhen you `move 1 spot`, it takes a hour and your `hunger will be deducted 1`. So, in **`a day`**, you can only take `24 steps` (unless you have [potion of swiftness](#potion-of-swiftness) ) before it gets dark.\nWhen it's `night` time, your `village` will be `attacked by nearby monsters` (if you can see them from the map in the village's perpective means is nearby) \n\u003eFor Example: \n![village_perspective](village_perspective.JPG)\n\n\u003e\u003evillage's perspective means the village is in the middle of the map\n\n*each nearby `monster` will have `10 damage times days you survived` to the village*. Once the *`night is over`* and you and your village are both ***`still alive`*** everything will *reallocate* to their new places *except you and your village*. This will *`start a whole new day`* of defending your village with new and more unexpected things to come. Your `default blood` will be `added to 20`. Your `village` will become stronger with `50 more blood`.\n***`But`*** if the `village falls down` or 'you died' during the day, you fail your mission, and the ***`game is over`***.\n\nFor example (after the night stats):\n1. Your day 2 stats (best condition) (Player)\n+ Blood: 20\n+ Strength: 2\n+ Hunger: 20\n+ Coins: 10 \n+ Level: 2\n\n2. Your village's day 2 (best condition) stats\n+ Blood: 100\n+ Strength: 0 \n+ Level: 2\n\n## Summary of the game\nYou and your village can't fall down.\n\n# Basic Interfaces\n## Basic\nThere are two main kinds of spot in the game. One is '.' and others.\n| Spots in map | Status |\n| ------ | ----------- |\n| '.'(dot) / 'p' | normal |\n| 'm' / 's' / 'f' / 'c' / 'h'...(even hidden ones) | special |\n\nWhenever you see a map, *`you are in the dead center of the map`*. If you don't see 'p' doesn't mean you are not on the map, it's just that you are standing on a special spot.\n## Movement Interface\nAsk which direction to go or you want to [use inventory](#inventory-how-to-use) or see map or quit game.\n\n![movement_interface](movement_interface.JPG)\n## After movement Interface\nEach time after you move you will be given all kinds of information.\n1. Village's stats\n2. Your stats\n3. What is in your inventory\n4. Effects on you\n5. Map\n6. Coordinate (Yours and Village's)\n7. Time of the day\n8. Small reminder\n   \n![interface](interface.JPG)\n## Village Interface\nAsk what you want to do in the [village](#what-can-you-do-inside-the-village)\n\n![village_interface](village_interface.JPG)\n## Dealer's Shop Interface\nAsk what you want to do in the [dealer's_shop](#dealer-shop)\n\n![dealer's_interface](dealer_interface.JPG)\n\n## Inventory Interface\nsee [inventory_interface](#inventory-how-to-use)\n# Setup\n## Intro\nThe game will first welcome adventurer and give you your stats. And then it will ask you to input the rows and columns of the map (suggestion: square and 50*50 or up) and then it will ask you to input the coordinates of the village. Then, you can choose to create a new map or start playing. You always `start from the village`.\n\n![setup](setup.JPG)\n## Item setup\n| Items | How Many |\n| ------ | ----------- |\n| [Player](#player)  | one |\n| [Village](#your-village) | one |\n| [Dealer](#dealer-shop)  | map size * 1/12 |\n| [Monster](#monster)  | map size * 1/8 |\n| [Food](#food)  | map size * 1/8 |\n| [Guns](#guns--shields--traps)  | map size * 1/24 |\n| [Shield](#guns--shields--traps)  | map size * 1/24 |\n| [Traps](#guns--shields--traps)  | map size * 1/24 |\n| [Fast Travel Stations](#fast-travel-stations)  | map size * 1/48 |\n| [Health Stations](#health-stations)  | map size * 1/48 |\nFor example: a 50*50 map \n![item_setup](item_setup.JPG)\n* The location of the items are randomly generated except for the village.\n\n# Items in the game\n## Player\nIs you\n\nIs `'p'` on the map\n\nsee [stats](#prerequisites)\n\n### Inventory (How to use)\nBefore you move, you can always use your inventory. You just need to type '0' and you can use it.\n\n![use_inventory](use_inventory.JPG)\n\n## Your Village\nIs `'v'` on the map\n\nsee [stats](#prerequisites)\n### What can you do inside the village\n1. Buy a magical sword\n   \n   Each sword is *3 coins* and will give you *1 strength*. You can only *buy once per visit*.\n2. Go to the bar\n\n    You can drink beer in the bar which will give you *+1 blood*. Each beer is worth *2 coins* and you can drink till you are back to health.\n3. Eat a meal\n   \n   Each meal is worth *5 coins* and will give you *+5 hunger*. You can eat till you're full.\n4. Sell things \n\n    You can sell things from your inventory but each thing is only `sold for 5 coins`.\n\n## Dealer Shop\nIs `'d'` on the map\n\nThe dealer shop is like a black market. It can highly improve your game. It sells unique things that you can't normally buy in your village. But because of this you can only buy stuff from this dealer shop once. Once you leave the shop you can only visit other shops in other locations, the shop you visited will `disappear` to avoid being arrested by the cops (there are actually no cops in this game, it is just to tell you that it is like a black market, and it will not be in the same location after you leave).\n\n### Things in the Dealer Shop\n\n#### Potion of Swiftness\nMakes you go faster, you can walk two steps at a time with only `-1 hunger`. *Effect lasts till the day ends*. Costs `25 coins`.\n#### Totem of Undying\nYou won't die if you have this. It will give you `+5 blood` when in need.\nCosts `50 coins`.\n#### Golden Apple\nWhen you eat it, it will give you `+5 blood and +5 hunger`.\nCosts `55 coins`.\n#### Potion of Good Vision\nYou can see `11 * 11 map` everytime you see the map. *Effect lasts till the end of the day*.\nCosts `30 coins`.\n\n### How to use the items\nYou have to go in your inventory (see [how to use inventory ](#inventory-how-to-use)) and use it then the item will be in effect.\nFor example, you want to use the totem of undying, go in your inventory and use it then it will be in effect otherwise no.\n* You can buy a lot of them but only use 1 of them (only 1 can be in effect)\n## Monster\nIs `'m'` on the map\n\nThere are four levels of monsters. When you `encounter` a monster, the `levels` of the monsters are `randomly generated`. You then can *choose to fight or not to fight*. If you choose to `fight` your `hunger` will first be `deducted by the monster's strength`, as you will need tired and hungry after the fight.\n\n| Monsters | Stats (Day 1) (Default) |\n| ------ | ----------- |\n| Lv. 1  | Blood: 1 Strength: 1 Coins:  5 |\n| Lv. 2  | Blood: 2 Strength: 2 Coins: 10 |\n| Lv. 3  | Blood: 3 Strength: 3 Coins: 15 |\n| Lv. 4  | Blood: 4 Strength: 4 Coins: 20 |\n* Monster's Stats  =  Default Stats * (Days you survived) . For example, on day 2, a lv.2 monster will have 4 blood, 4 strength, and 20 coins. \n* When you encounter a monster, each `monster's evasion rate` will be `randomly generated`, and when a monster `successfully` evaded your attack, it will `attack back` (will lose blood). If it `didn't evade`, it means you attacked successfully if your `attack is greater than their blood`. You will `get` the `coins` and your `strength` will be `added 1`, but if your attack is `lesser` than their blood, it means you `lost`, and `you` will be `attacked` (will lose blood). The monster won't go anywhere if you lose, so you can always come back again(may be different level). But the monster will disappear if you win, because you just killed it.\n  \n## Food\nIs `'c'` on the map, as it stands for chicken or cow\n\nWhen you encounter a \"food\", you can eat it, and your hunger will be `added 2`. If you are already full, then the game will say you are full and you don't need to eat it (to save animals). But the animal will go nowhere so you can come back anytime. But if you are almost full (if +2 hunger will be greater than 20 hunger) then you will only be added to 20 hunger.\n\n## Guns / Shields / Traps\nThey are all over the map, but hided from you( can't see from map ) . Each '.' may be a gun, shield, or a trap, so walk with caution.\nAfter you stepped on it, it will disappear (not in the same location).\n| Hidden Items | Description |\n| ------ | ----------- |\n| Guns  | Will give you strength. ( strength +1 ) |\n| Shield  | Will give you protection ( blood+1 ). |\n| Trap 1  | Will lose 1 blood and 1 strength|\n| Trap 2 | Will lose coins |\n* The amount of coins you lose is somewhere between 0 to half your amount (random). So don't be worried.\n* If you don't have any strength (strength = 0) then the next time you lose strength you will lose blood. see [if your strength/hunger/coins = 0](#if-your-strength--hunger--coins--0) for more info\n  \n## Fast Travel Stations\nIs `'f'` on the map\nThey can help you `travel back to the village` right away if you want.\n\n## Health Stations\nIs `'h'` on the map\nIt will give you `+1 blood`. But if you are already healthy, you don't need it.\n\n# Functions and Variables\n## Variables\n### Monster stats\n``` c\ntypedef struct\n{\n    int blood;\n    int strength;\n    int coins;\n    int level;\n    int evasionRate;\n} info; \n//for monster\n``` \n### Player Stats\n``` c\ntypedef struct\n{\n    int default_blood;\n    int blood;\n    int strength;\n    double hunger;\n    int coins;\n    int level;\n    int rp;           // player row coordinate\n    int cp;           // player column coordinate\n    int rv;           // village row coordinate\n    int cv;           // village column coordinate\n    int boot;         // for calculating time of the day\n    int day;          // what day it is\n    inventory things; // like backpack\n    inventory effect; // what effects are on me\n} adventurer;\n// for hero\n``` \n### Inventory\n```c\ntypedef struct\n{\n    int potion_of_swiftness;\n    int totem_of_undying;\n    int golden_apple;\n    int potion_of_good_vision;\n} inventory;\n//inventory\n```\n### Village Stats\n```c\ntypedef struct\n{\n    int blood;\n    int strength;\n    int level;\n} village;\n// for village\n```\n## Create Map\n``` c\nchar **create_map(int *row, int *col)\n{\n    //ask for row and col\n    printf(\"Input the number of row and column for the map (suggestion square and 50*50 or up):\\n\");\n    scanf(\"%d %d\", row, col);\n\n    //malloc\n    char **arr = (char **)malloc(*row * sizeof(char *));\n    for (int i = 0; i \u003c *row; i++)\n        arr[i] = (char *)malloc(*col * sizeof(char));\n\n    //set all to '.'\n    for (int i = 0; i \u003c *row; i++)\n        for (int j = 0; j \u003c *col; j++)\n            arr[i][j] = '.';\n    return arr;\n}\n```\n## Decide to travel or not\n```c\nint travel_decide()\n{\n    int decide; // decide to create a new map or travel\n    printf(\"[0] Create a new map [1] Start travel the map:\");\n    scanf(\"%d\", \u0026decide);\n    return decide;\n}\n```\n## Check for availability and boundaries\n  1.
