Calculate average of odd and even numbers in C++

Calculate average of odd and even numbers in C++

In this tutorial, we will discuss a concept of the  C++ code to calculate the average of odd and even numbers.

In this article, we are going to learn  how to  calculate the Average of odd and even numbers  in the C++ programming language

Calculate the average of odd and even numbers

What is an even or odd number?

When any integer ends in 0,2,4,6,8 and it can be divided by two with the remainder of zero, it is called as an even number.

Example of even numbers – 34,-64,78,788

When any integer ends in 0,1,3,5,7,9 and it cannot be divided without a remainder, it is called as an odd number.

Example for odd numbers – 33,-69,75,785

 

Here, We can use a modular operator to find odd or even number in the range of numbers

if n%2==0,  n is an even number – if the number is even, the remainder is zero.

if n%2==1,  n is an odd number – if the number is odd, the remainder is one.

 

Calculate the average of odd and even using for loop

Program 1

This program allows the user to enter a value and calculate average of odd and even numbers until the entered number using “for loop”.

Program

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int i,num, oddSum=0,evenSum=0,oddCount=0,evenCount=0;    //1
double evenAvg,oddAvg;                     //2
    cout<<"Enter the value for num: ";     //3
    cin>>num;

    for(i=1; i<=num; i++){           //4
 if(i % 2==0){               //5
  evenSum=evenSum+i;
  evenCount++;
 }
 else{                            //6
  oddSum=oddSum+i;
  oddCount++;
 }

    } 
evenAvg=evenSum/evenCount;                      //7
oddAvg=oddSum/oddCount; 
cout<<"Average of odd numbers are: "<<oddAvg;    //8
cout<<"\n";
cout<<"Average of even numbers are: "<<evenAvg;
getch();
    return 0;
}

When the above code is executed, it produces the following results

Enter the value for num: 60
Average of odd numbers are: 30
Average of even numbers are: 31

Method:

  1. To begin with , declare and initialize four variables to find  sum as oddSum=0, evenSum=0, oddCount=0 and evenCount=0;
  2. Declare two variables for find average named as avgOdd, avgEven;
  3. Next, a number is received from the user as an input for variable num
  4. Then, using the “for loop”, elements are picked one by one from the numbers to determine oddness and evenness.
  5. Next, “if statements” are used to find a number and then if it is even, it is added to evenSum.If the number is not even, it is dealt with by  “else statement”.
  6. After that, the “else statement” adds to oddSum.
  7. Then, find the average of odd and even numbers
  8. Finally, the average of odd numbers and even numbers are displayed.

 

Calculate the average of odd and even numbers in C++ using while  loop

program

This program allows the user to enter a value and calculate average of odd and even numbers until the entered value using “while loop”.

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int i,num, oddSum=0,evenSum=0,oddCount=0,evenCount=0;  //1
double evenAvg,oddAvg;        //2
    cout<<"Enter the value for num: ";    //3
    cin>>num;
   i=1;
    while(i<=num){             //4
    if(i % 2==0){               //5
        evenSum=evenSum+i;
        evenCount++;
    }
    else{                     //6
        oddSum=oddSum+i;
        oddCount++;
    }
     i++;
    }
evenAvg=evenSum/evenCount;       //7
oddAvg=oddSum/oddCount;
cout<<"Average of odd numbers are: "<<oddAvg;     //8
cout<<"\n";
cout<<"Average of even numbers are: "<<evenAvg;
getch();
    return 0;
}

When the above code is executed, it produces the following results

Enter the value for num: 35
Average of odd numbers are: 18
Average of even numbers are: 18

Method:

  1. To begin with , declare and initialize four variables to find  sum as oddSum=0, evenSum=0, oddCount=0 and evenCount=0;
  2. Declare two variables for find average named as avgOdd, avgEven;
  3. Next, a number is received from the user as an input for variable num
  4. Then, using the “while loop“, elements are picked one by one from the numbers to determine oddness and evenness.
  5. Next, “if statements” are used to find a number and then if it is even, it is added to evenSum.If the number is not even, it is dealt with by  “else statement”.
  6. After that, the “else statement” adds to oddSum.
  7. Then, find the average of odd and even numbers
  8. Finally, the average of odd numbers and even numbers are displayed.
