Powers I

C++ PROGRAM

POWERS (without using in-built function)

In this program the user will enter any number 'a' and the power 'b' (which can be any whole number), and the output will be a^b, that is, 'a' raised to the power 'b'.

In this program I will not use the in-built function for calculating powers. I will use only 

for-loop.

Code:

#include<iostream.h>

#include<conio.h>

void main()

{

double a,b,i,p=1;

cout<<"Powers"<<\n";

cout<<"Enter any number: "

cin>>a;

cout<<"Raised to the power: ";

cin>>b;

for(i=1;i<=b;i++)

{

 p=p*a;

}

cout<<"Ans. "<<p;

getch();

}

Output:

First Run:

Second Run:

In the next program (Powers II), I will use in-built function for calculation of powers.
