What is pow on c++? How and when do you use it?

Question

A code would be helpful thanks!

Answer 1

It means power or raised to... It gives the value for x raised to n

eg:- 2^3 is 8

#include <iostream>
#include <cmath> // Header needed
using namespace std;

int main() {
cout<<pow(2,3); //outputs 8
return 0;
}

Answer 2

As I learned quite recently, C++ is a language which does not have an exponentiation operator like ** or ^
Instead, it uses a regular method imported from its math module - pow(x, y)
It shows you the y-th power of x, like pow(2,5) equals 2*2*2*2*2 or 32

Answer 3

Power function is needed
#include <cmath> library or #include <bits/stdc++.h> library
For example :
#include <bits/stdc++.h>
using namespace std;
int main (){
cout << pow(5,2) << endl;
return 0;
}
Output: 25
