Program to find sum of all elements of an array through pointer

 Program sum of all elements in an array through pointer :--

Code:-

#include<stdio.h>

#include<stdlib.h>

int findsum(int n,int *a)

{

int i,sum=0;

for(i=0;i<n;i++)

{

sum+=*(a+i);

}

return sum;

}

int main()

{

int n,*a,i,res;

printf("Enter the size of array ");

scanf("%d",&n);

a=(int*)malloc(n* sizeof(int));

printf("Enter the elements ");

for(i=0;i<n;i++)

{

scanf("%d",a+i);

}

res=findsum(n,a);

printf("Sum of elements is %d ",res);

return 0;

}

Output:--

Enter the number of element 6

Enter the element 3 6 2 10 4 5

Sum of elements is 30
