# C++ Program To Read Integer (N) And Print First Three Powers (N^1,N^2,N^3)

Problem :- Write A C++ Program To Read Integer (N) And Print First Three Powers (N^1,N^2,N^3) Example If user Enter a 5 From Keyboard Then Output Should be 5 ,25 ,125 Means power of number in 1 ,2 ,3

Logic :- For this problem We Need to multiply Number or we can use power function for that take a example for better understood this problem take a Number 5 as input and multiply with same number again like 5*5 for cube we need to again multiply with same number like 5*5*5 or we can use power function

Power Function  Syntax ;- for given example  xy .

pow(x,y)

also define the datatype of x and y .

Solution :-

Method 1 :- Simple Without Using Power Function

#include<bits/stdc++.h>
using namespace std;
int main()
{
/*Program By Ghanendra Yadav

*/
int num;
cout<<"\nEnter The Number .\n";
cin>>num;
cout<<"\nOutpout is \n";
cout<<num<<"  ,"<<num*num<<"  ,"<<num*num*num<<endl;
return 0;

}

Method 2 :- Using Power Function

#include<bits/stdc++.h>
using namespace std;
int main()
{
/*Program By Ghanendra Yadav
Visit http://www.programmingwithbasics.com/
*/
int num,a,b,c;
cout<<"\nEnter The Number .\n";
cin>>num;
a=pow(num,1);
b=pow(num,2);
c=pow(num,3);
cout<<"\nOutpout is \n";
cout<<a<<"  ,"<<b<<"  ,"<<c<<endl;
return 0;
}

Output:-
