Use the following Code :

#include

bool letterCheck$($char x$[],$ char y$[],$ int len, char c$,$ int $*$times$)$;

int main$()\{$

$/*$ Type your code here. $*/$

return $0$;

$\}$

bool letterCheck$($char x$[],$ char y$[],$ int len, char c$,$ int $*$times$)\{$

$//$ checks if letter c exists in x$[].$ Discovered letters are stored in y$[].$

$//$times holds how many

$//$ times c appeared in x$.$
