Write a function to accept a vector of chars and a char and return a count of how many times the char appears in the vector.

Choose the answer below that best implements this function.

$```$

int countChar$($const vector &V$,$ char ch$)$

$\{$

int count;

for$($int i $=0$; i $$ V$.$size$()$; i$++)$

if $($V$[$i$]==$ ch$)$

count$++$;

return count;

$\}$

$```$

None of the other answers are correct. $```$

int countChar$($const vector &V$,$ char ch$)$

$\{$

int count $=0$;

for$($int i $=0$; i $$ V$.$size$()$; i$++)$

if $($V$[$i$]==$ ch$)$

count$++$;

return count;

$\}$

$```$

$```$

void countChar$($const vector &V$,$ char ch$)$

$\{$

int count $=0$;

for$($int i $=0$; i $$ V$.$size$()$; i$++)$

if$($V$[$i$]==$ ch$)$

count$++$;

cout $$ "The count is $"$ count $$ endl;

$\}$
