**Input from user:**

Enter elements in 1st matrix of size 3x3:

1 2 3

4 5 6

7 8 9

Enter elements in 2nd matrix of size 3x3:

1 2 3

4 5 6

7 8 9

**Expected output:**

Subtraction of matrices=

__Logic of matrix Subtraction__:

**Matrix Subtraction is done element wise. Means Subtraction of matrices is defined by A-B= A↓ij - B↓ij.**

** Step by Step logic of the given program:**

1. Accept two matrices from user declare varible say arr1 and arr2(use 2 dimensional array to store elements).

2. Store elements one by one in arr1 using:

for(row=0;row<size;row++)

{

for(col=0;col<size;col++)

{

scanf("%d", &arr1[row][col]);

}

}

Follow same these steps for arr2.

3. Subtract two matrices arr1-arr2 element wise using:

for(row=0;row<size;row++)

{

for(col=0;col<size;col++)

{

arr3[row][col] = arr1[row][col] - arr2[row][col];

}

}

4. Last print Subtraction of two matrices means resultant matrix arr3.

#include<stdio.h>

#define size 3 // size of the matrix

int main()

{

int arr1[size][size]; // 1st matrix

int arr2[size][size]; // 2nd Matrix

int arr3[size][size]; // Resultant matrix

int row, col;

/* input elements in first matrix*/

printf("Enter elements in 1st matrix of size 3x3:\n");

for(row=0;row<size;row++)

{

for(col=0;col<size;col++)

{

scanf("%d", &arr1[row][col]);

}

}

/* input elements in second matrix */

printf("\nEnter elements in 2nd matrix of size 3x3: \n");

for(row=0; row<size;row++)

{

for(col=0;col<size;col++)

{

scanf("%d", &arr2[row][col]);

}

}

/* subtract both matrices arr1 and arr2 and store result in matrix arr3*/

for(row=0;row<size;row++)

{

for(col=0;col<size;col++)

arr3[row][col] = arr1[row][col] - arr2[row][col];

}

}

4. Last print Subtraction of two matrices means resultant matrix arr3.

** C program to print subtraction of two matrices using array:**

#include<stdio.h>

#define size 3 // size of the matrix

int main()

{

int arr1[size][size]; // 1st matrix

int arr2[size][size]; // 2nd Matrix

int arr3[size][size]; // Resultant matrix

int row, col;

/* input elements in first matrix*/

printf("Enter elements in 1st matrix of size 3x3:\n");

for(row=0;row<size;row++)

{

for(col=0;col<size;col++)

{

scanf("%d", &arr1[row][col]);

}

}

/* input elements in second matrix */

printf("\nEnter elements in 2nd matrix of size 3x3: \n");

for(row=0; row<size;row++)

{

for(col=0;col<size;col++)

{

scanf("%d", &arr2[row][col]);

}

}

/* subtract both matrices arr1 and arr2 and store result in matrix arr3*/

for(row=0;row<size;row++)

{

for(col=0;col<size;col++)

{

arr3[row][col] = arr1[row][col] - arr2[row][col];

}

}

/* Print the value of resultant matrix arr3 */ printf("\nSubtraction of matrices = \n");

for(row=0; row<size;row++)

{

for(col=0; col<size;col++)

{

printf("%d ",arr3[row][col]);

}

printf("\n");

}

return 0;

}

Above program shows the following

arr3[row][col] = arr1[row][col] - arr2[row][col];

}

}

/* Print the value of resultant matrix arr3 */ printf("\nSubtraction of matrices = \n");

for(row=0; row<size;row++)

{

for(col=0; col<size;col++)

{

printf("%d ",arr3[row][col]);

}

printf("\n");

}

return 0;

}

Above program shows the following
