Magic Square with C++

This time we will create magic squares with applications using the programminglanguage C. Earlier, I'll explain what that magic squares;

Magic square is a symmetry matrix is the sum of all lines are equal, eitherhorizontal, vertical, or diagonal. For example, I will give examples of magicsquares with the order of 3x3.

8 1 6
3 5 7
4 9 2
To make the application, I have prepared a flowchart, scripts and sample results.This application can only be used for the order is odd, because the even do not know the plot. J

This flowchart:

Source Code :

#include void main(){ static int i, j, a, b[20][20],x=1, input,c; printf("masukkan jumlah ordo = "); scanf("%d", &input); c = input*input; j = (input/2); for(i=0, a=1; a<=c; i--, j++, a++){ if(x == 0){ i+=2; j-=1; } else if(i<0){ i += input; } else if(j>=input){ j -= input; } b[i][j] = a; x = a%input; } for(i=0; i for(j=0; j printf("%d \t", b[i][j]); printf("\n"); } }

Output :
