#include <stdio.h>
int main()
{printf("a        a^2    a^3\n1        1      1\n2        2      8\n3        3      27\n4        4      64\n");
return 0;
}

#include<iostream>
using namespace std;
int main()
{

	cout<<"a        a^2    a^3"<<endl;
	cout<<"1        1      1"<<endl;
	cout<<"2        2      8"<<endl;
	cout<<"3        3      27"<<endl;
	cout<<"4        4      64"<<endl;
	return 0;
}

Java :

public class Main {
	public static void main(String[] args) {
		System.out.println("a        a^2    a^3");
		System.out.println("1        1      1");
		System.out.println("2        2      8");
		System.out.println("3        3      27");
		System.out.println("4        4      64");
