- Solution

Learn to implement C++ template solutions using function and template arguments. Understand how recursive templates enable compile-time calculations, and explore the interplay between runtime and compile-time evaluation to enhance flexibility and code reuse.

We'll cover the following...

Solution 1: Using Function Arguments #

C++
// power1.cpp
#include <iostream>
int power(int m, int n){
  int r = 1;
  for(int k=1; k<=n; ++k) r*= m;
  return r;
}
int main(){
  std::cout << power(2,10) << std::endl;
}

Explanation #

We’re using a for loop to compute the power. The loop runs a total of n times by multiplying the number m by r for every iteration of the loop in line 7.
