beginner here need help with an array code

Ohshtdude · 02-01-2009, 04:30 PM

hey im a beginner to C++ and I'm looking for a bit of help in one of my programs, I havent done much with arrays in C++ but I'm looking to get an array of 10 randomly assigned integers, find a way to add them together and print out the result, as well as add all the numbers of the even index of the array and subtract all the numbers in the odd index of the array and put those in two different results. Can someone walk me through this?

Right. The homework policy here at Cprogramming.com is that you show us what you've done and we will help you - not "Post your homework assignment and someone will post back the answer".

If you are dealing with a[i], how can you tell whether i is even or odd?

Ohshtdude · 02-01-2009, 05:37 PM

no like a[0] being even a[1] being odd a[2] being even etc

how about adding 2 in each iteration?

Right. So how do you know that 0 is even, 1 is odd, 2 is even, etc?
