I am working on a program in which you input a number for quarters, nickels, dimes, and pennies. It will then put it in the following output:
Enter quarters: 3
Enter Dimes: 12
Enter Nickels: 15
Enter Pennies: 26
The input change amounts to 296 cents, using 56 coins.
The same change could be made with:
Quarters = 11
Dimes = 2
Nickels = 0
Pennies = 1
Total coins = 14
I would appreciate any suggestions in which you may have. My professor is out of town until next thursday. Here is the code I have accomplished so far:
.model small
.stack 100h
extrn Indec : proc
extrn outdec : proc
.data
;prompts
msg1 db 10,13, "Enter the number of QUARTERS: $"
msg2 db 10,13, "Enter the number of DIMES: $"
msg3 db 10,13, "Enter the number of NICKELS: $"
msg4 db 10,13, "Enter the number of PENNIES: $"
msg5 db 10,13, "The input change amounts to X cents using Y coins."
msg6 db 10,13, "The same change could be made with:"
Quarters db 0dh, 0ah, 'Quarters: $'
; Dimes db 0dh, 0ah, 'Dimes : $'
; Nickels db 0dh, 0ah, 'Nickels : $'
; Pennies db 0dh, 0ah, 'Pennies : $'
TotalCoins db 0dh, 0ah, 'The total number of Coins is: $'
