## helloWorld
使用 g++ 编译程序，试过 gcc 不好使。后期查过 c 编译使用 gcc, c++ 编译使用 g++。
```
g++ -o helloworld helloworld.cpp
```
## 2. 常量
```cpp
/**
* 常量的定义方式
* 1. #define 宏常量
* 2. const 修饰的常量
**/
#include
using namespace std;
#define DAY 7
int main() {
cout << "一周总共多少天" << DAY << "天"<< endl;
// const 修饰的变量
const int month=12;
cout << "一年有" << month << "月份"<< endl;
return 0;
}
```
