Ravencroft·:
So I'm trying to make a program that calculates the average of five numbers by sending them to a function called SUM to calculate the sum, then return to MAIN to calculate the average. I'm having trouble figuring out how to return to MAIN though. Here's what I have so far:

This is my first program using functions so point out any other syntax issues there might be.

Headcrab Zombie:
First off, return isn't a function, so you don't do return(SUM);
It's just return SUM;

Then you need a call to that function after the inputs: float sum = SUM(a,b,c,d,e);

Also, you're missing an ending curly brace at the end of main

That's odd. My lecture notes say to have parentheses around the return variable. There's even parentheses on it on the example code snippets.
And yeah I know I'm missing a brace. I tried removing it thinking the main function had to be wrapped around the sum function. So how exactly would I continue with the main function after returning? Do I put the code in the first main function brackets or start a new main function after the sum function(talking about the part where the average is calculated and output to the user)?

The main issue is that you've left the SUM function inside the main function, when it's supposed to be outside the main function. Like so:

--- Code: ---#include <stuff>

using namespace std;

float SUM(float a, float b, float c, float d, float e)
{
return a + b + c + d + e;
}

int main(void)
{
// Your code defining values and collecting their data

float answer = SUM(a, b, c, d, e);
cout << "The answer is " << float << endl;
}

--- End code ---
