Programming Example
Assignment: Using C Language: Add all element in the array.
Add all elements in the array
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.
Implement a function that takes an array of integers and returns the sum of all elements in that array.
Example 1:
[1, 2, 3, 4, 5]15 (because 1 + 2 + 3 + 4 + 5 = 15)Example 2:
[-10, 20, -30, 40]20 (because -10 + 20 - 30 + 40 = 20)// 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;
}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
First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
