C program to calculate sum in array elements

C program to calculate sum in array elements

In this tutorial, we will discuss C program to calculate sum in array elements

In this topic, we will learn code to how to calculate sum of elements in integer array in C programming language.

Calculate the sum of array elements

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int array[]={45,67,53,47,65,32,45,78};//Array declaration and initiation
    int sum,count;//variable declaration
    sum=0;
    for(count=0; count<=7; count++){//loop iterates to calculate sum
        sum=sum+array[count];
    }
    printf("Sum of array is %d",sum);//display result on the screen
    getch();
    return 0;
}

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

Sum of array is 432

 

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 essential variables with initialization
3. for loop iterates to each value to the variable
4. Add each element of the sum variable from the array
5. finally, display result on the screen

Calculate the sum of array elements – takseinput from user

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int array[5];//Array declaration
    int sum,i,j;//variable declaration
    for(i=0; i<=5; i++){
        printf("Enter the elements for array[%d]: ",i);
        scanf("%d",&array[i]);//loop iterates to take input from the user
    }
    sum=0;
    for(j=0; j<=5; j++){//loop iterates to calculate sum
        sum=sum+array[j];
    }
    printf("\nSum of array elements is %d",sum);
    getch();
    return 0;
}

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

Enter the elements for array[0]: 56
Enter the elements for array[1]: 78
Enter the elements for array[2]: 98
Enter the elements for array[3]: 75
Enter the elements for array[4]: 46
Enter the elements for array[5]: 76

Sun of array elements is  358

 

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 for getting the input valuef
4. or loop iterate each value for calculating the variable
5. Add each element of the sum variable from the array
6. finally, display sum on the screen
