Print number of times an input was given, and take the average of the inputs

[vileoxidation]

Hello, and thanks for any help in advance!

Basically, as the title says, I am looking for a way to print the number of times the user gave the program an input, and then also print the average of all the inputs.

So far, I have initialized three variables as follows:

int counter=0;
int sum=0;
float average=0;
 

Do I need to use a loop to do this? I have also written the expressions for the three variables:

sum = sum + size;
counter = counter + 1;
average = sum/counter;
 

I have tried printing the values of counter and average, and I get a negative counter value and a nonense average value.

So, in summary, do I need a loop to print the number of inputs and their average? Also, using a loop or not, how do I get the second three lines of code to work correctly?

Thank you in advance for any help!!

Yes you need to declare size and since you are keeping track of sum, count and average you need to control with a loop. You also need to input something with cin>>.At the moment the three variable = 0 and you are also dividing by 0

I already have declared size, and have an input already set for size, and the program, which prints squares, works perfectly except for this part. I just didn't want to post too much code.

But how do I actually set up the loop using them? That is the problem I am having.

You could do something like this:

cout<<"Enter an integer";
for(int i=0;i<20;i++)
{cin>>integer;
numberIntegersEntered+=1;
sum+=integer;
averageSum=sum / numberIntegersEntered;
cout<<"The average of the integers entered is: "<<averageSum<<endl;
//if this was a function you could add:
return numberIntegersEntered;//and display this value
