Magic Square Program

[CornholeChamp1]

What am i doing wrong? Why is it not reading in correctly? I get a negative value.

Write a program to determine if a 3 x 3 array filled with integers is a Magic Square. A Magic Square is when you sum each row, each column, and the two diagonals. This means that all the sums (8 of them) are all the same value. That is the sum of the three values on row 0 equal the sum of row 1 equal to sum of row 2 equal to sum of col 0, 1, 2 and equal to the sum of the major and minor diagonals.


Output:
You are to print out the 2-D array by rows (one row per line), then print if the Square is Magic Square or not and if the Square is Magic, also print the sum value.


Input: Your input file is MagicSquare.txt.

The input file looks like this:

Did you spell magicSquare.txt incorrectly?

ifstream inFile("MagicSqaure.txt"); //open file for reading

[CornholeChamp1]

No that's how he has it.

[CodeWriter]

So you have checked that the actual text file is spelled that way?

Well I saved as a text file the data I gave above as magicSquare.txt

With the incorrect name of magicSqaure.txt in the code for the file used I get with your code,

2293512
2293700

With the correct name I gave my file, magicSquare.txt, I get with your code,
