Sum of Elements in an Array using For Loop in C Programming

This program is a simple C program that accepts a number as the limit of an array and then prompts the user to input values for that array. It then prints out the values of the array, followed by the total of all the values in the array.

It first declares variables i, j, n, and an array a[10] of integers. Then it prompts the user to enter the limit of the array using the scanf function. Next, it prompts the user to enter values for the array using a for loop and the scanf function.

Then, it uses another for loop to print out the values of the array, one at a time, along with their index. Then it iterates over the array, adding each element to the variable 'j' which is initially set to 0. Finally, it prints the total of all the values in the array, which is stored in the variable 'j'. It uses for loop and scanf function to take the input from the user and printf function to display the output on the console.

#include<stdio.h>
int main()
{
  int i,j=0,n,a[10];
  printf("\nEnter the Limit:");
  scanf("%d",&n);
  printf("\nEnter the values:");
  for(i=0;i<n;i++)
  {
    scanf("%d",&a[i]);
  }
  printf("\nGiven values are:");
  for(i=0;i<n;i++)
  {
    printf("\na[%d]=%d",i,a[i]);
  }
  for(i=0;i<n;i++)
  {
    j=j+a[i];
  }
  printf("\nTotal value is:%d",j);
  return 0;
}
