How to count the white spaces in a string in C

Answer 1

#include <stdio.h> 

int count_white_paces_in_string(char* s) {
    int white_paces = 0;
    char* p = s;

    while (*p != '\0') {
        if (*p == ' ' || *p == '\n' || *p == '\t' || *p == '\r') {
            white_paces++;
        }
        p++;
    }

    return white_paces;
}

int main(void)
{
    char *s = "C \r Programming \n Developer \t  ";

    printf("white spaces = %i", count_white_paces_in_string(s));

    return 0;
}
