C Exercises: Subtraction of two Matrices
C Array: Exercise-20 with Solution
Write a program in C for the subtraction of two matrices.
Pictorial Presentation:

Sample Solution:
C Code:
#include <stdio.h>
void main()
{
int arr1[50][50],brr1[50][50],crr1[50][50],i,j,n;
printf("\n\nSubtraction of two Matrices :\n");
printf("------------------------------\n");
printf("Input the size of the square matrix (less than 5): ");
scanf("%d", &n);
/* Stored values into the array*/
printf("Input elements in the first matrix :\n");
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
printf("element - [%d],[%d] : ",i,j);
scanf("%d",&arr1[i][j]);
}
}
printf("Input elements in the second matrix :\n");
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
printf("element - [%d],[%d] : ",i,j);
scanf("%d",&brr1[i][j]);
}
}
printf("\nThe First matrix is :\n");
for(i=0;i<n;i++)
{
printf("\n");
for(j=0;j<n;j++)
printf("%d\t",arr1[i][j]);
}
printf("\nThe Second matrix is :\n");
for(i=0;i<n;i++)
{
printf("\n");
for(j=0;j<n;j++)
printf("%d\t",brr1[i][j]);
}
/* calculate the subtraction of the matrix */
for(i=0;i<n;i++)
for(j=0;j<n;j++)
crr1[i][j]=arr1[i][j]-brr1[i][j];
printf("\nThe Subtraction of two matrix is : \n");
for(i=0;i<n;i++){
printf("\n");
for(j=0;j<n;j++)
printf("%d\t",crr1[i][j]);
}
printf("\n\n");
}
Sample Output:
Subtraction of two Matrices : ------------------------------ Input the size of the square matrix (less than 5): 2 Input elements in the first matrix : element - [0],[0] : 5 element - [0],[1] : 6 element - [1],[0] : 7 element - [1],[1] : 8 Input elements in the second matrix : element - [0],[0] : 1 element - [0],[1] : 2 element - [1],[0] : 3 element - [1],[1] : 4 The First matrix is : 5 6 7 8 The Second matrix is : 1 2 3 4 The Subtraction of two matrix is : 4 4 4 4
