ft_putstr

ft_putstr.c

#include <unistd.h>

void ft_putstr(char *str)
{
    // Define and initialize an unsigned integer variable 'i' to 0
    unsigned int i = 0;

    // Loop until the null character ('\0') is encountered in the string pointed to by 'str'
    while (str[i])
    {
        // Call the 'write' function to output the character at the current position in the string,
        // specified by the value of 'i', to standard output (stdout)
        write(1, &str[i], 1);

        // Increment 'i' by 1 after each iteration
        i++;
    }
