how find average code example

Example 1: average calculator

1. make an array nums[number of neumbers you will calculate the average of] 
   wich will store the numbers and a variable sum=0 (make it double)
2. input that array with a loop 
3. in the loop, after you have entered nums[i] add it to sum
4. after loop output sum divided by the number of numbers

code in c++:

#include <iostream>

using namespace std;

int main()
{
	long long nums[ 5 ];  // I used 5 cus I like the number 5. 
                          //Could have been 3 or 10 or whatever.
    double sum = 0;
    
    for( long long i = 1 ; i <= 5 ; i++ )
    
    {
    
    	cin >> nums[ i ];
        
        sum += nums[ i ];
    
    }
    
    cout << sum / 5 << endl ;
    
    return 0;
    
    }

Example 2: Calculation of Average

This program is to calculate the average of two numbers.
The numbers are 3 and 5.
The average is:  4.0
