C++ MAGIC SQUARE
write a program that generates a magic square for an array of size 3*3.
step1: use a 2d array of 3*3
step2: fill array with unique values 1-9 genrerated at random (ex. (rand()%9)+1)
use a function to check and see if the random numbers generated have been previously generated in the array,(check for unqiueness)
if the number is unique,store it in your 2d array
step3:display the 2d array
step4:check if thr 2d array is a magic square
(sum of each row=sum of each col.=sum of each diagonal)
step5:keep repeating the loop of steps1-4 until a magic square is found.
EX:
1 2 3
4 5 6
7 8 9
Not magic
2 3 1
4 5 6
7 8 9
not Magic
2 7 6
9 5 1
4 3 8
IS Magic
I CAN'T FIGURE OUT HOW TO OLNY HAVE THE NUMBER USED ONCE IN THE SQURE(NEED TO HAVE NONREPEATING NUMBERS)

: The program should not exit when it encounters an error in the expression. Rather, it should output error information and then accept the next expression.
