Question: The prompt is to create an HLA Assembly language program that prompts for a single integer value from the user and prints a v pattern.
The prompt is to create an HLA Assembly language program that prompts for a single integer value from the user and prints a v pattern. If the number is negative, don't print anything at all. DO NOT use ifforor while loops.
Please fix the error in the following code:
program Question;
#include "stdlib.hhf;
static
n: int; User input
i: int; Row iterator
j: int; Column iterator
begin Question;
Prompt for an integer input and read it into n
stdout.put "Enter a positive integer for the V pattern: ;
stdin.getN;
Check if n is negative; if so terminate the program without output
test EBX, EBX ;
js ExitProgram;
Outer loop to handle each row i to n
mov i ;
OuterLoop:
cmp i n ;
jg EndOuterLoop; Exit loop if i n
Print leading spaces on the left side of the V j to i
mov j ;
LeftSpacesLoop:
cmp j i ;
jge EndLeftSpaces; Exit loop if j i
stdout.put;
inc j ;
jmp LeftSpacesLoop;
EndLeftSpaces:
Print the integer n for the left side of the V
stdout.puti n ;
Print middle spaces between the two n values j i to n
mov i j ;
inc j ;
MiddleSpacesLoop:
cmp j n ;
jge EndMiddleSpaces; Exit loop if j n
stdout.put;
inc j ;
jmp MiddleSpacesLoop;
EndMiddleSpaces:
Print the integer n again for the right side of the V
Only print the second n if it's not the last row i n
cmp i n ;
je SkipRightSide;
stdout.puti n ;
SkipRightSide:
Move to the next line and increment i for the next row
stdout.newln;
inc i ;
jmp OuterLoop;
EndOuterLoop:
ExitProgram:
end Question;

For mathrmn the output would look like:
