CODE IN C Using template below complete the following write

*****CODE IN C++ Using template below, complete the following:

-write the introductory comments and code to output the user’s input

-write the code that determines if the user’s input creates a Lo Shu Magic Square, Magic Square, or not a magic square. The code has been written that the user can create up to a 20 by 20 square. You may assume the user does not enter a size greater than 20.

/* Add your introductory comments here. */
#include <iostream> using namespace std;
int main() { int magicsquare[20][20];
int rowsandcolumns; cout << \"What size of a magic square would you like to test?\"
<< \"\ (Because it is a square the number of rows equals the number
of columns.) \";
cin >> rowsandcolumns;
                 //assume the user enters a value <= 20
cout << \"Enter the values for the square one value at a time.\"; //assume the user enters correct values
for (int r = 0; r < rowsandcolumns; r++) {
for (int c = 0; c < rowsandcolumns; c++) {
cout << \"Enter the value for row \" << r + 1 << \" column \" << c
+ 1 << \". \";
cin >> magicsquare[r][c];
}
} //Print out their input array here as a table
//test if it is a Lo Shu Magic Square, Magic Square (not Lo Shu), // or not a magic square and output the result
return 0;
}
