write in mips

Write a program that implements the following C code:

$//$ This can be a global variable declared using the $.$asciiz directive.

char $*$ my$\_$string $=$ "hello";

int main$()$

$\{$

$//$ Call our replace$\_$start$\_$with$\_$z function on our global string.

replace$\_$start$\_$with$\_$z$($my$\_$string$)$;

$//$ Print our global string. Use the function in util.s for this.

PrintString$($my$\_$string$)$;

$//$ It is generally a good idea to return $0$ from main when no errors

$//$ occurred. However, the autograder will not test you on this.

return $0$;

$\}$

void replace$\_$start$\_$with$\_$z$($char $*$ string$\_$to$\_$change$)$

$\{$

int length $=$ strlen$($string$\_$to$\_$change$)$;

if $($length $>0)$

$\{$

string$\_$to$\_$change$[0]=\text{'}$Z$\text{'}$; $//$ Change the beginning character

$//$ to a capital Z$.$

$\}$
