Question

What am I doing wrong here...….

Question is this :

In this exercise, you will create a program that displays a table consisting of four rows
and three columns. The first column should contain the numbers 10 through 13. The
second and third columns should contain the results of squaring and cubing, respec-
tively, the numbers 10 through 13. The table will look similar to the one shown in
Figure 9-38. If necessary, create a new project named Introductoryl6 Project, and save
it in the Cpp8\Chap09 folder. Enter your C++ instructions into a source file named
Introductoryl6.cpp. Also enter appropriate comments and any additional instructions
required by the compiler. Test the program appropriately.

Here is what I have so far, but it is not calculating it correctly nor displaying the right properties.

//Introductory16.cpp - displays table with squared and cubed calculations
//Created/revised by Kristen Arnold February 8th, 2019

#include <iostream>
#include <cmath>
#include <iomanip>
using namespace std;

int main()
{
int dummy;

int num = 0;

cout << "Number " << "Square Root " << "Cube " << endl;
for (num = 10; num < 14; num += 1)
{
  cout << num << sqrt(num) << pow(num, 3) << endl;

} // end for

cin >> dummy;

return 0;

} //end main function

#include <iostream>
#include <cmath>
#include <iomanip>
using namespace std;

int
main()
{
int dummy;

int num = 0;

cout << "Number "
       << "Square Root "
       << "Cube " << endl;
for (num = 10; num < 14; num += 1) {
    cout <<setw(3)<< num <<setw(10) << pow(num,2) <<setw(10)<< pow(num, 3) << endl;//squaring andnot taking the square root
    //using setw() to set the width of each field. Experiment with the numbers and see for yourself how the output changes

} // end for

cin >> dummy;

return 0;

} // end main function
