Answer to Question #39395 in C++ for Theodore

Question #39395
I am new to C++ and have been trying to understand the function below, I need a step by step of what it is actually doing, its a function that takes a BASE and a power it works but wish to know how exactly it works. I can do base calculation off the top of my head but this is a little different. #include<stdio.h> int pw(int,int); int main() { int x,n,ans; printf("Enter the numbers:base and power\n"); scanf("%d%d",&x,&n); ans=pw(x,n); printf("The ans is: %d\n",ans); return 0; } int pw(int x,int n) { int i,y=1; if(n==0) return 0; else if(n==1) return x; else if(n==2) return(x*x); else { y=x*x; for(i=3; i<=n; i++) { y=y*x; } return (y); } }
