Cpp program to calculate the sum of array elements

In this tutorial, we will discuss the Cpp program to calculate the sum of array elements.

In this topic, we will learn how to calculate the total value of array elements.

 

Program 1

This program calculates the total value of numbers stored in an array

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

int main()
{
    int array[]={25,65,46,76,89,72,54,27,36}; //declare and initialize array
    int count,sum=0;//variable declaration
    for(count=0; count<=8; count++){
        sum=sum+array[count];//calculate sum of array elements
    }
    cout<<"Sum of array elements is: "<<sum;
    getch();
    return 0;
}

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

Sum of array elements is: 490

 

In this program, we can see some of the steps by step procedures given below

1. Create an array and define its values
2. Define neediest variables with initialization
3. for loop iterate to each value to the variable
4. Add each element of the sum variable from the array
5. finally, display sum on the screen

 

Program 2

This program takes n number of elements from user store in an array and calculating the total value of those number

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

int main()
{
    int array[6];
    int sum,i,j;
    for(i=0; i<=6; i++){
        cout<<"Enter the elements of array: "<<"array"<<"["<<i<<"]: ";
        cin>>array[i];
    }
    sum=0;
    for(i=0; i<=6; i++){
        sum=sum+array[i];
    }
    cout<<"\nSum of array elements is: "<<sum;
    getch();
    return 0;
}

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

Enter the elements of array[0]: 45
Enter the elements of array[1]: 76
Enter the elements of array[2]: 89
Enter the elements of array[3]: 97
Enter the elements of array[4]: 63
Enter the elements of array[5]: 72
Enter the elements of array[6]: 70

Sum of array elements is: 448

 

In this program, we can see some of the steps by step procedures given below

• Create an array and define its values
• Define essential variables with initialization
• loop for iterate to each value for getting the input value
• for loop iterate each value for calculating the variable
• Add each element to the sum of the variable from the array
• finally, display sum on the screen
