C Program to Compute Determinant of a Matrix on Command Line

In this tutorial, I’m going to share the details about “C Program to Compute Determinant of a Matrix on Command Line“. Let’s start the tutorial to see the possibilities to do this task successfully.

C Program to Compute Determinant of a Matrix on Command Line

#include<stdio.h>

int main(){

int a, i, j;

long determinant;
printf("Enter the 9 elements of matrix: ");
for(i = 0 ;i < 3;i++)
for(j = 0;j < 3;j++)
scanf("%d", &a[i][j]);

printf("nThe matrix isn");
for(i = 0;i < 3; i++){
printf("n");
for(j = 0;j < 3; j++)
printf("%dt", a[i][j]);
}

determinant = a * ((a*a) - (a*a)) -a * (a
* a - a * a) + a * (a * a - a * a);

printf("nDeterminant of 3X3 matrix: %ld", determinant);

return 0;
}
