# 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);

}

}

#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);

}

}
