Whats the output of this question?? Just need the output!

Give the output of the C program shown below: #include int f (char *str, char ch) if '\0' ( str [0] return 0 ) == if ( str [0] = ch ) return 1+ f (str+1, ch) return f (str+1, ch) int main() ( printf (" a is %d ", f("bama", 'a') ); printf ("b is %d ", f ( "cs 100", '0') ); printf ( "c is %d ", f("111223", 'l') ); printf ("d is %d ", f("xoxox", 'x') ); return 0
