7.8.2.void function with return statement
#include <iostream> 
using namespace std; 
 
void power(int base, int exp)
 
int main() 

  power(102);
  power(10, -2)
 
  return 0

 

void power(int base, int exp

  int i; 
 
  if(exp < 0return/* Can't do negative exponents. */ 
 
  i = 1
 
  for; exp; exp--
     i = base * i; 
  cout << "The answer is: " << i; 
  return;
}
The answer is: 100
