Powers II

C++ PROGRAM

POWERS (using in-built function)

The code of this program will be shorter than the previous one (Powers I) because in this I will use the in built function, pow(a,b), to calculate powers.

This function is available in the header file: <math.h>.

This is even more useful because we can also find fractional powers of numbers such as 

4^0.5, which is it's square root, i.e, 2.

Code:

#include<iostream.h>

#include<conio.h>

#include<math.h>

void main()

{

clrscr();

double a,b;

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

cout<<"Enter any number: ";

cin>>a;

cout<<"Raised to power: ";

cin>>b;

cout<<"Ans. "<<pow(a,b);

getch();

}
