The following code should determine whether or not a square of numbers is a magic square or not. The code debugs and run just fine, but the command prompt opens, asks me how many squares I would like to calculate for, and after I hit enter with a number, it just sits there and does nothing.

Can anyone tell me why it does that? Have I done anything wrong?

Code:#include <iostream>#include <fstream> #include <iomanip> using namespace std; const int size = 5; void square (int x[size][size]); void heading(); ifstream infile; ofstream outfile; int main() { infile.open("input.txt"); outfile.open("output.txt"); int c; cout << "How many squares would you like to determine? "; cin >> c; cout << endl; heading; outfile << "The user of this program has chosen to determine whether " << c << " squares are magic squares." << endl << endl; int x[size][size]; for (int c = 1; c > 0; c++) { for (int d=0; d<size; d++) for (int e=0; e<size; e++) infile >> x[d][e]; square(x); } system("pause"); return 0; } // This function writes the heading in the outfile. void heading() { outfile << "Trey Brumley" << endl; outfile << "CMPS 1063 - Johnson" << endl; outfile << "January 29, 2013" << endl; outfile << "Program 1 - Magic Squares" << endl; outfile << "=========================" << endl << endl; outfile << "This program will take a certain number of number squares as determined by the user, and it will compare the sums of each row, column, and diagonal." << endl; outfile << "A magic square is a square of numbers with a constant sum of each of its rows, columns, and diagonals." << endl << endl; return; } // This function will test a square one row at a time void square (int x[size][size]) { infile.open("input.txt"); outfile.open("output.txt"); int sum = 0, sum2 = 0; int y=1, z=1; //This and the following loop will determine a sum, which will remain constant. //A second sum of the next row will be determined, which will repeatedly be tested against the first sum. //If the sums are equal, the loop will continue to run. If not, the function will end. for (y; y <= 5; y++) sum += x[y][z]; while (z<5) { sum2 = 0; for (y=1; y<=5; y++) sum2 += x[y][z]; if (sum2 != sum) { outfile << "This square is not a magic square." << endl; return; } else z++; } for (z=1; z<=5; z++) while (y<=5) { sum2 = 0; sum2 += x[y][z]; if (sum2 != sum) { outfile << "This square is not a magic square." << endl; return; } else y++; } sum2 = 0; //The following loops will test diagonals. for (z=1; z<=5; z++) { y=z; sum2 += x[y][z]; if (sum2 != sum) { outfile << "This square is not a magic square." << endl; return; } } sum2 = 0; for (z=1; z<=5; z++) { y=6-z; sum2 += x[y][z]; if (sum2 != sum) { outfile << "This square is not a magic square." << endl; return; } } outfile << "This square is a magic square. The constant sum is " << sum << "." << endl; return; }
