Difference of matrix

Q. Write a C program to accept value of matrix and print out the difference or subtract  of matrix.

OR

Q. Give a example of 2d array with suitable arithmetic operation. 

Ans.

/*program of difference of two matrix*/

#include<stdio.h>

#include<conio.h>

#define MAX 3

void input_mat(int [MAX][MAX], int, int);

void show_mat(int [MAX][MAX], int, int);

void diff_mat(int [MAX][MAX],int [MAX][MAX],int [MAX][MAX],int,int);

int main()

{

 int x[MAX][MAX],y[MAX][MAX],z[MAX][MAX];

 int row,col;

 printf("Enter no. of rows and columns : ");

 scanf("%d%d",&row, &col);

 printf("Enter values in first matrix :\n");

 input_mat(x,row,col);

 printf("Enter values in second matrix :\n");

 input_mat(y,row,col);

 diff_mat(x,y,z,row,col);

 printf("\nDisplay difference of two matrices :");

 show_mat(z,row,col);
 getch();

 return 0;
}

void input_mat(int matA[MAX][MAX], int r, int c)

{

  int i,j;

  for(i=0; i<r; i++)

  {

    for(j=0;j<c; j++)

       scanf("%d",&matA[i][j]);

  }

}

void diff_mat(int matA[MAX][MAX],int matB[MAX][MAX],int matC[MAX][MAX],int r,int c)

{

  int i,j;

  for(i=0; i<r; i++)

  {

    for(j=0;j<c; j++)

       matC[i][j]=matA[i][j]-matB[i][j];

  }

}

void show_mat(int mat[MAX][MAX], int r, int c)

{

  int i,j;

  for(i=0; i<r; i++)

  {

    for(j=0;j<c; j++)

       printf(" %d",mat[i][j]);

    printf("\n");

  }

}

Output:-

Enter no. of rows and columns : 3 3

Enter values in First matrix :

4 5 3

7 6 1

6 9 5

Enter values in second matrix :

1 3 2

7 6 4

5 1 0

Display difference of two matrices :

3 2 1

0 0 -3

1 8 5
