Assignment: Summing Elements in an Array

Objective:

Write a program that reads a specified number of integers into an array, calculates the sum of all elements in the array, and displays the result.

Task:

Implement a function that takes an array of integers and returns the sum of all elements in that array.

Parameters:

  • array: An array of integers that you will populate based on user input.

Result:

  • sum: The total sum of all integers in the array, which will be displayed to the user.

Constraints:

  • The array should contain at least one integer.
  • Each integer can be positive or negative.
  • The maximum number of elements in the array is 10.

Example Scenarios

Example 1:

  • Input: [1, 2, 3, 4, 5]
  • Result: 15 (because 1 + 2 + 3 + 4 + 5 = 15)

Example 2:

  • Input: [-10, 20, -30, 40]
  • Result: 20 (because -10 + 20 - 30 + 40 = 20)

Program:

// Add all element in the array

#include<stdio.h> 
void main()
{
int array[10],n, i, value;
printf("Enter How many elemnts you want to insert in array: ");
scanf("%d",&n) ;
for(i= 0; i<n; i++)
{
  printf("array[%d]: ",i);	
  scanf("%d",&array[i]);
}

value = addelements(array,n);   // function calling
printf("Add value = %d \n",value);
}

  
int addelements(int array[],int size)
{
	int i,add;
	add=0;
    for(i=0;i<size;i++){ 
        add+=array[i];
    }
    return add;
}

Output:

Enter How many elemnts you want to insert in array: 5
array[0]: 2
array[1]: 3
array[2]: 4
array[3]: 5
array[4]: 6
Add value = 20
