sum of all the elements of an array using pointer IN C program

 C- program to find the sum of all the elements of an array using pointer  

This is  a C program to find the answer of sum of  the array elements using pointer 
Problem Description 
calculate the sum of array elements using pointer.  This c program add the array elements  values uses pointer.
problem solution
  •   First create a pointer variable  , which point an int data.
  •   Take a size of array as input.
  •   after create a size of array  * size of all array elements
  • after iterate for loop taking element as input.
  • again use for loop to access the address stored in pointer ,add the iterator value , so as to all access elements of array .


source code

This source code of the C program  to calculate the sum of array using pointer . this program successfully compilied and tested by netbeans .


Program  


#include <stdio.h>
#include <stdlib.h>
int main(int argc, char** argv)
{
    int *p,a[20];
    int i, n, sum = 0;
    printf("enter the size of array \n");
    scanf("%d",&n);
    printf("\n give the elements one by one ");
    for(i=0;i<n;i++)
        scanf("%d",&a[i]);
    p=a;
    for(i=0;i<n;i++)
    {
        sum = sum+*p;
        ++p;
    }
    printf("\n\n The sum of array element:%d",sum);

    return (EXIT_SUCCESS);
}

Output


sum of all the elements of an array using pointer IN C program

Q1 Write a c program to check a voting AGE condition Given age of someone and that we ought to check whether person is eligible for voting or not. To check that someone is eligible for voting or not, we'd like to examine whether or not person’s age is bigger than or up to eighteen. For this we tend to are reading age in a very variable a and checking the condition a>=18, if the condition is true, "person are eligible for voting" else no. #include <stdio.h> #include <stdlib.h> int main(int argc, char** argv) {         int a;     printf("ENTER A AGE\n");     scanf("%d",&a);     if (a>=18)     {         printf("YOU CAN VOTE");             }     else     {         printf("YOU CAN'T VOTE...
