Write a program to accept 10 numbers and display its sum using pointer.​

Introduction

In this program, we will learn to accept 10 numbers and display its sum using pointer.

Algorithm

  1. Start
  2. Declare an array of 10 integers.
  3. Declare a pointer variable.
  4. Initialize the pointer variable.
  5. Accept 10 numbers as input.
  6. Use a cycle to add the elements to the variable sum.
  7. Display the sum.
  8. End

Code

Practical-16.c
//Include the function stdio.h that allows us to use the Input/Output functions
#include<stdio.h>

//Define a macro to set the size
#define SIZE 10

int main ()
{
  //Declare and define the variables
  int numbers[SIZE];
  int *numptr;
  int sum = 0;
  int i;

  //We use a cycle to accept 10 numbers as input
  for(i=0;i<SIZE;i++)
  {
    printf("Enter your number: ");
    scanf("%d",&numbers[i]);
  }

  //We set the *numptr of the array numbers
  numptr = numbers;

  //We use a cycle that adds the elements to the variable sum
  for (i=0;i<SIZE;i++)
  {
    sum += *numptr;
    numptr++;
  }

  //Display the sum
  printf("The sum is: %d",sum);

  //End of program

}

Output

Enter your number: 1
Enter your number: 2
Enter your number: 3
Enter your number: 4
Enter your number: 5
Enter your number: 6
Enter your number: 7
Enter your number: 8
Enter your number: 9
Enter your number: 10
The sum is: 55
Explanation

The program starts by declaring an array of 10 integers, a pointer variable, a variable sum and a variable i. Then, we initialize the pointer variable and use a cycle to accept 10 numbers as input. We set the *numptr of the array numbers and use a cycle that adds the elements to the variable sum. Finally, we display the sum.
