How to Write a Program That Exponentiates using C

In this video I will show you how to write a program that exponentiats in C. More precisely, given the base x and the exponent n, this program will return the value of x^n. I hope this video helps someone.

I love that you use C! A true sorcerer

Just a few nitpickey things, but you should forward declare the power function before main and include the variable types in the parameters of power.

Nice job ....just came handy when I didn't understand what I was doing and being mixed up ...This was very helpful... hope you make more nice and pleasant videos...keep it up !

This is Amazing!, I'm just now taking a C course in my university and this came in the perfect moment, are you planning to do pointers and strings? I'm struggling a bit with those, I would love to see you explaining them a bit in the future! :D

You can also use recursion, which greatly simplifies things (by applying the definition of exponentiation: x⁰ = 1, xⁿ⁺¹ = x · xⁿ):

double power(double base, unsigned exponent) {
if(exponent == 0) {
return 1;
}
return base * power(base, exponent - 1);
}

Hey Soccer
I ask how can we calculate x^n when n is rational or even irrational? I think we can use the definition of e^x as a sum, but idk how.

Hey, do you do zoom tutoring for basic algebra? I have to take an ASVAB test for military. I really like your no non sense, straight forward teaching style. Please reach out if so.

Really amazing please make more video like this please

[Wandering_Horse]

Well this was unexpected and a pleasant surprise. Nice 👍🏼

Hello Sir I have a question for you In trying to learn math like solving rational equations
But I seem to forget what I’ve learned I studied how to solve them but after 4-5 days I don’t remember it could you give me some tips how to not forget any math problem

[stankdog]

You should do some python programming videos!

[sainithinreddy]

sir your code takes o(n) to run consider the below code it takes o(logn) to run

#include <bits/stdc++.h>
using namespace std;

long long power(long long a, long long b) {
long long result = 1;
while(b) {
if (b & 1)
result = result * a;
a = a * a;
b >>= 1;
}
return result;
}

int main() {
int x, y;
cin>>x>>y;
cout<<power(x, y)<<"\n";
return 0;
}

Too much code, and slow.

double pow(double x, int n)
{
if (n == 0) return 1;
return (n > 0) ? x * pow(x, n - 1) : 1 / x * pow(x, n + 1);
}

There are also faster ways to do this with the FPU. In Computer Science, we normally agree 0^0 = 1. It allows things to work. I wouldn't use this though. This is a more practical way of looking at the exponents. Welcome to programming in C.

oh come on, you're a mathematician. use haskell!
