Instead of counting the number of spaces in a string, it might be more useful to generalize a function so that it counts any character. Write the function count$\_$char.

#include

#include

using namespace std;

$/**$

Gets the number of times the character c appears in the string.

@param str any string

@param c the single$-$character string to search for

@return the number of times c appears in str

$*/$

$/*$ Your code goes here $*/$

$\{$

int count $=0$;

for $($int i $=0$; i $$ str$.$length$()$; i$++)$

$\{$

if $(/*$ Your code goes here $*/)\{$ count$++$; $\}$

$\}$

return count;

$\}$

int main$()$

$\{$

string str;

string c;

getline$($cin$,$ str$)$;

cin $>>$ c;

cout $$ count$\_$char$($str$,$ c$)$ endl;

return $0$;

$\}$
