exception related bug i guess

Question

please find the bug in the program below and inform me . It would be much appreciated.

/* This program can solve 3 equations by using cramers rule. */

//importing modules
#include <stdio.h>

//creating the fuctions
int determinant(int a11, int a12, int a13, int a21, int a22, int a23, int a31, int a32, int a33) {
int step_1, step_2, step_3;
step_1 = (a22*a33) - (a23*a32);
step_2 = (a21*a33) - (a23*a31);
step_3 = (a21*a32) - (a31*a22);
int det_result = (a11*step_1) + (a13*step_3) - (a12*step_2);
return(det_result);
}

//main function
int main () {
//getting user input
int i;
printf("Enter the coefficients of the first equation. Press enter after writing each value to give input.\n => ");
int ed1[3] = {};
for (i = 0; i <= 3; i++) {
scanf("%d", &ed1[i]);
}
printf("Enter the coefficients of the second equation. Press enter after writing each value to give input.\n => ");
int ed2[3] = {};
for (i = 0; i <= 3; i++) {
scanf("%d", &ed2[i]);
}
printf("Enter the coefficients of the third equation. Press enter after writing each value to give input.\n => ");
int ed3[3] = {};
for (i = 0; i <= 3; i++) {
scanf("%d", &ed3[i]);
}

//main mathod
int dx, dy, dz, d, x, y, z;
d = determinant(ed1[0], ed1[1], ed1[2], ed2[0], ed2[1], ed2[2], ed3[0], ed3[1], ed3[2]);
dx = determinant(ed1[3], ed1[1], ed1[2], ed2[3], ed2[1], ed2[2], ed3[3], ed3[1], ed3[2]);
dy = determinant(ed1[0], ed1[3], ed1[2], ed2[0], ed2[3], ed2[2], ed3[0], ed3[3], ed3[2]);
dz = determinant(ed1[0], ed1[1], ed1[3], ed2[0], ed2[1], ed2[3], ed3[0], ed3[1], ed3[3]);
x = dx/d;
y = dy/d;
z = dz/d;
printf("x = %d \ny = %d \nz = %d \n", x, y, z);
}

You can ***link*** your code like this: Go to Code section, click +, select the programming language, insert your code, save. Come back to this thread, click +, Insert Code, sort for My Code Bits, select your code.

This way the code is easier to read and people can test it.
