Create an HLA function that determines if a passed character parameter is a period or exclamation letter. This function should have the following signature:

procedure isPeriodOrExcl$($ c : byte $)$; @nodisplay; @noframe;

This function should return into EAX an int$32$ value which is either true or false, $1$ or $0.$ To receive full credit, your isPeriodOrExcl$()$ function must not allocate any storage.

Your function should replicate the following C code:

bool isPeriodOrExcl$($ char c $)$

$\{$

bool result $=$ false;

if$($ c $==\text{'}.\text{'}$ && c $==\text{'}!\text{'})$

$\{$

result $=$ true;

$\}$

return$($ result $)$;

$\}$

IN ORDER TO RECEIVE FULL CREDIT, YOU MUST USE THE TEMPLATE SOLUTION SHOWN BELOW. Of course, you will need to add code to the function to implement the desired algorithm explained above. In addition, you will need to push the parameters to the function.
