# 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[3][3], 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[0][0] * ((a[1][1]*a[2][2]) - (a[2][1]*a[1][2])) -a[0][1] * (a[1][0]
* a[2][2] - a[2][0] * a[1][2]) + a[0][2] * (a[1][0] * a[2][1] - a[2][0] * a[1][1]);

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

return 0;
}``````
