I have a string, let\'s say \"THESTRINGHASNOSPACES\".

I need something that gets a substring of 4 characters from the string. In the first call, I should get \"THES\

#include 
#include 

int main() {
    char src[] = "SexDrugsRocknroll";
    char dest[5] = { 0 }; // 4 chars + terminator */
    int len = strlen(src);
    int i = 0;

    while (i*4 < len) {
        strncpy(dest, src+(i*4), 4);
        i++;

        printf("loop %d : %s\n", i, dest);
    }
}
