libs21

libs21 is a static library that contains functions for various tasks from school 21.

Contents

This library contains the following functions:

• split: Split string using some delimiter
• to_lower: Converts string to lowercase
• to_upper: Converts string to uppercase
• load_bmp: Read bmp file into unsigned char array
• bmp_data_to_grayscale: Converts bmp data into grayscale

Requirements

To use this library, you'll need the following:

A clang++ that supports C++17 or later

Building

To build the library, simply run make in the project directory. This will compile the library into a static archive file named libs21.a.

Using

To use the library in your own project, you can include the header files for the functions you need and link against the libs21.a file. For example, if you wanted to use the foo function from the library in your own program:

#include <stdio.h>
#include "libs21.h"

int main() {
    printf("%s\n", s21::to_upper("hello world!"));
    return 0;
}

Then you can compile your program with:

gcc -o myprogram myprogram.c -I/path/to/libs21/include -L/path/to/libs21

Make sure to replace /path/to/libs21 with the actual path to your libs21 project directory.
