## C Program to Subtract Two Matrices Using Multidimensional Arrays

In this program, the user is asked to enter the elements of the two matrices a and b. Then the elements of these two matrices are subtracted and saved it in third matrix. Finally, the result (third matrix) is printed on the screen.

##### Source Code
``````#include<stdio.h>
void main()
{
int a[3][3], b[3][3], c[3][3], i, j;

printf("Enter the first matrix\n");
for(i=0;i <3; i++)
{
for(j=0; j<3; j++)
{
scanf("%d", &a[i][j]);
}
}
printf("Enter the second matrix\n");
for(i=0;i <3; i++)
{
for(j=0; j<3; j++)
{
scanf("%d", &b[i][j]);
}
}
printf("Subtraction of matrices A & B is\n");
for(i=0;i <3; i++)
{
for(j=0; j<3; j++)
{
c[i][j] = a[i][j] - b[i][j];
printf("%2d ", c[i][j]);
}
printf("\n");
}
}``````
##### Output
``````Enter the first matrix
4 5 6
7 8 9
1 2 3
Enter the second matrix
8 4 3
5 7 9
12 4 9
Subtraction of matrices A & B is
-4 1 3
2 1 0
-11 -2 -6``````
