HOW TO PASS ARRAY IN FUNCTION

 

    SUM OF ALL ELEMENTS OF ARRAY

 

#include <iostream>
using namespace std;
 
int abc(int brr[], int n)   //abc is the name of function
{
              int sum=0;
              for(int i=0; i<n; i++)
              {
                             sum+=brr[i];
              }
              return sum;
}
 
int main()
{
int n = 10;
int arr[n]= {1,2,3,4,5,6,7,8,9,10};
 
cout<<"Sum is : "<<abc(arr,n)<<endl;
              return 0;
}

 

 

   AVERAGE OF ALL ELEMENTS OF ARRAY

 

#include <iostream>
using namespace std;
 
double getAverage(int arr[], int size)
{
  int i, sum = 0;      
  double avg;         
 
   for (i = 0; i < size; i++) {
      sum += arr[i];
   }
  
   avg = double(sum) / size;
 

   return avg;
}
 
int main () {
 
   int balance[] = {1000, 2, 3, 17, 50};
  
   cout << "Average value is: " <<   getAverage( balance, 5 )  << endl;
 
   return 0;
}
