/**
 * @brief Locates the first occurrence of a character in a string.
 *
 * This function searches for the first occurrence of the character `c`
 * in the string `s`. The null-terminator character `\0` is considered part
 * of the string, so `c` can also be `\0` to locate the end of the string.
 *
 * @param s The string to search in.
 * @param c The character to locate, passed as an `int` but interpreted
 *          as `char`.
 * @return char* A pointer to the first occurrence of the character `c`
 *         in the string `s`, or NULL if the character is not found.
