# CS50 Library for C

[![Build Status](https://travis-ci.org/cs50/libcs50.svg?branch=master)](https://travis-ci.org/cs50/libcs50)

## Development

`make`: builds dynamic library

`make deb`: builds source deb

`make install`: installs the library under `/usr/local` by default (set `DESTDIR` to change that)

## Installation

### Ubuntu

```

$ curl -s https://packagecloud.io/install/repositories/cs50/repo/script.deb.sh | sudo bash

$ sudo apt-get install libcs50

```

### Fedora

```

$ curl -s https://packagecloud.io/install/repositories/cs50/repo/script.rpm.sh | sudo bash

$ yum install libcs50

```

### From Source (Linux and Mac)

1. Download the latest release from https://github.com/cs50/libcs50/releases

1. Extract `libcs50-*.*`

1. `cd libcs50-*`

1. `sudo make install`

By default, we install to `/usr/local`. If you'd like to change the installation location, run

`sudo DESTDIR=/path/to/install make install` as desired.

## Troubleshooting

1. If, when compiling a program, you see `/usr/bin/ld: cannot find -lcs50`:

Add `export LIBRARY_PATH=/usr/local/lib` to your `.bashrc`.

1. If, when compiling a program, you see `fatal error: 'cs50.h' file not found`:

Add `export C_INCLUDE_PATH=/usr/local/include` to your `.bashrc`.

1. If, when executing a program, you see `error while loading shared libraries: libcs50.so.8: cannot open shared object file: No such file or directory`:

Add `export LD_LIBRARY_PATH=/usr/local/lib` to your `.bashrc`.

Close and reopen any terminal windows.

## Usage

Link with `-lcs50`.

    #include 

    ...

    char c = get_char("Prompt: ");

    double d = get_double("Prompt: ");

    float f = get_float("Prompt: ");

    int i = get_int("Prompt: ");

    long l = get_long("Prompt: ");

    string s = get_string("Prompt: ");

    // deprecated as of fall 2017

    long long ll = get_long_long("Prompt: ");

## Documentation

See `man get_*` after installation, or [CS50 Reference](https://reference.cs50.net/cs50/)!
