Create an HLA function that loops through a single string argument and verifies that last character found in the string is a capital A .
Create an HLA function that loops through a single string argument and verifies that last character found in the string is a capital A This function should have the following signature:
procedure endsWithA stringData : dword ; @nodisplay; @noframe;
This function should return into EAX an int value which is either true or false, or To receive full credit, your endsWithA function must not allocate any storage.
You must use the utility functions gets and puts provided here Download hereby downloading this file. Unzip it to find the hla file inside. These are the some of the same routines you used in Unit Once you acquire the file, you can include it in your code by saying: #includecsstring.hla" ;
Your function should replicate the following C code:
bool endsWithA char stringData
int i ;
char letter ;
while stringData i NULL
loop the last character
letter stringData i ;
i i ;
return letter A;
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.

Please look at the two TODO: notes below

Place it in the same folder as this hla file you are working on

Several hints are supplied
procedure endsWithA stringData : dword ; @nodisplay; @noframe;

begin endsWithA;
TODO: CS Students will need to preserve registers
pop dReturnAddress ;
TODO: CS Students need to get stringData off the stack

this code allocates a string of size
mov @size int AL ;
mov BL ;
inc BL ;
mul BL ;
mov EBX ;
mov AX BX ;
malloc EBX ;
mov EAX, stringData ;
let's try reading a value into the string
mov stringData, EAX ;
push EAX ;
mov CX ;
push CX ;
call gets;
print the string
stdout.put here is the string you entered: ;
mov stringData, EAX ;
push EAX ;
call puts;
stdout.newln;
initialize EAX before calling the function.
mov EAX ;
TODO: CS Students need to pass a string parameter to the function
call endsWithA;
mov EAX, answer ;
show the results
stdout.put "after endsWithA result;
stdout.put answer ;
stdout.newln;
end StringProgram;
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 value which is either true or false, or To receive full credit, your isLower function must not allocate any storage.
Your function should replicate the following C code:
bool isPeriodOrExcl char c
bool result false;
if c && c
result true;
return result ;
