Question

I will attach file. I need help on how to start the program I am confused as to what strings to use.

Answer 1

hmm, just a thought

change = 100 - price

while change>0
{
if change >= 25
change=change - 25
q=q+1

if change < 25 and change >= 10
change=change - 10
d=d+1

if change < 10 and change >= 5
change=change - 5
n=n+1
}

your change is therefore, q quarters, d dimes, and n nickels

Answer 2

Actually, this is a recursive problem, but what @amistre64 wrote is the basic logic, it just needs to be able to go through it one or more times until it reaches 0.
