Hints

strcpy(dest, src) copies; strcat(dest, src) appends.

The destination must be big enough.

Solution explanation

You can't use = or + on C strings - use the string.h functions.

Show solution

#include <stdio.h>
#include <string.h>

int main() {
    char first[50], last[50], full[110];
    scanf("%s %s", first, last);
    strcpy(full, last);
    strcat(full, ", ");
    strcat(full, first);
    printf("%s\n%d\n", full, (int) strlen(full));
    return 0;
}
