Rewrite the following function so that it does not use any square brackets $($not even in the parameter declarations$)$ but does use the integer variable k$.$ Do not use any of the functions such as strlen, strcpy$,$ etc.

$//$ This function searches through str for the character chr$.$

$//$ If the chr is found, it returns a pointer into str where

$//$ the character was first found, otherwise nullptr $($not found$).$

const char$*$ findTheChar$($const char str$[],$ char chr$)$

$\{$

for $($int k $=0$; str$[$k$]!=0$; k$++)$

if $($str$[$k$]==$ chr$)$

return &str$[$k$]$;

return nullptr;
