In this tutorial you will learn about the C Program to Find Sum of all Elements in an Array and its application with practical example.
C Program to Find Sum of all Elements in an Array
In this tutorial, we will learn to create a C program that will Find Sum of all Elements in an Array using C programming.
Prerequisites
Before starting with this tutorial, we assume that you are the best aware of the following C programming topics:
- Operators in C Programming.
- Basic Input and Output function in C Programming.
- Basic C programming.
- For loop in C programming.
- Arithmetic operations in C Programming.
What is An array?
The array is a collection of similar data types. An array can store multiple values with different indexes in memory by using a single variable. The array can be both single as well as multidimensional.
Program description to Find Sum of all Elements in an Array.
In this program, we will first take the input array size and the elements from the user. Then we will add all the elements of the array. At last, we will print that sum of numbers.
With the help of this program, we can Find Sum of all Elements in an Array.

/* C Program to Find Sum of all Elements in an Array */ #include<stdio.h> int main() { //Declaring the required variables for the program. int Size, i, a[10]; int sum = 0; //i = it will hold the integer value to control the loop. //a[10] = it will hold the integer value. //Size = it will hold the integer value. //sum = it will hold the integer value. //Taking the input numbers of elements from the user printf("\n Please Enter the Size of the Array\n"); scanf("%d", &Size); //Taking the elements of the array printf("\nPlease Enter the Array Elements\n"); //Start at 0, it will save user enter values into array a for(i = 0; i < Size; i++) { scanf("%d", &a[i]); } // Loop Over Array, and add every array item to sum for(i = 0; i < Size; i ++) { sum = sum + a[i]; } //printing the sum of elements of the array. printf("Sum of All Elements in an Array = %d ", sum); return 0; } |
Output:-
In the above program, we have first initialized the required variable.
- sum = it will hold the integer value for the sum of numbers.
- a[] = it will hold the integer value of the input elements.
- i = it will hold the integer value.
- Size = it will hold the integer value of the input.
Input number of elements from the user.
Program Logic Code.
Printing output sum.
