2. 25. 1. Demonstrate register variables


#include <iostream> 

using namespace std; 

 

int f(int nums[], int n); 

 

int main() 

{ 

  int vals[] = { 1, 2, 3, 4, 5 }; 

  int result; 

 

  result = f(vals, 5); 

 

  cout << "Summation is " << result << "\n"; 

 

  return 0; 

} 

 

int f(int nums[], int n) 

{ 

  register int i; 

  register int sum = 0; 

 

  for(i = 0; i < n; i++) 

    sum = sum + nums[i]; 

 

  return sum; 

}

Summation is 15
