C Program to find the average of elements using concept of pointers. Pointer stores the address of an element, so basically we are passing the address of the elements to the function average to obtain the desired output.
This program will clear your concept of passing array as a pointer.
#include <stdio.h>
int average(int *array,int n);
int main(){
int a[20],*array,n,i;
printf("enter number of elements");
scanf("%d",&n);
for(i=0;i<n;i++){
printf("enter %d element",i+1);
scanf("%d",&a[i]);
}
array=a;
average(array,n);
}
int average(int *array,int n){
int i,sum=0;
float avg;
for(i=0;i<n;i++){
sum+=*(array+i);
}
avg=(float)sum/6;
printf("average is %f",avg);
return avg;
}
Output
