C++ Power Operator

The power function looks like pow() inside we put argument ten and raise it to the second power pow(10,2) return 100.

pow() Syntax

The syntax of the pow() function is:

			
					pow(double base, double exponent);

			
	

			
	
			

		
	

pow() Parameters

The pow() function takes two parameters:

• base - the base value
• exponent - exponent of the base

C++ Power

Use Power Operator in c++

pow() function is not made available to us. By default, we need to import <cmath>

			
					#include <iostream>
#include <cmath>

using std::cout;
using std::cin;

int main() {
  int base, exponent;
  cout << "Enter Base : ";
  cin >> base;
  cout << "Enter Exponent : ";
  cin >> exponent;
  cout << pow(base, exponent);
}

			
	

			
	
			

		
	

output :

			
					Enter Base : 2
Enter Exponent : 4
16

			
	

			
	
			

		
	

We get a huge number if we have pow(10,10) return 1e+10 1 times 10 to the 10th power.We can assign a variable to that.

			
					#include <iostream>
#include <cmath>

using namespace std;
int main() {
  int base, exponent;
  double result;
  base = 6;
  exponent = 2;
  result = pow(base, exponent);
  cout << result << endl;
  return 0;
}

			
	

			
	
			

		
	

output 36
