THE PROBLEM: Design and write a program in MASM that will prompt the user to enter an integer value. This integer value will be used by the program to print out a series of right triangles built out of asterisks '*'. Each of the triangles will be printed out one at a time using loops. Each of the triangles should also be between three and nine asterisks high, and the same number across, but in different configurations.

Example:

Input : 3

My code does not do this, it is the last bit line4

org 100h

.model small

.stack 64

.data

;Question the user of the input. input db "Enter the size for the triangles, between 3 to 9, or 0 to quit: $"

size dw ?
