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.

Cpp program to calculate sum of array elements — Calculate the sum of array

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

Create an array and define its values
Define neediest variables with initialization
for loop iterate to each value to the variable
Add each element of the sum variable from the array
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
