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

procedure isLower$($ 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 isLower$()$ function must not allocate any storage.

Your function should replicate the following C code:

bool isLower$($ char c $)$

$\{$

bool result $=$ false;

if$($ c $>=$a$$ && c $<=$z$)$

$\{$

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.

end CharProgram;
