Not sure what you want to test but

for N = 1 to 100
for M = 1 to 100
'perform test
next
next

will give you the loop structure you want.

How to write a simple program to:


Test all possible combinations of adding two numbers that range from
1-100 each (10,000 total possible combination) using some sort of
looping structure.



My guess (and I'm new at programming) is that there will be some sort
of nested loops but the logic escapes me.
