# C Exercises: Addition of two Matrices

## C Array: Exercise-19 with Solution

Write a program in C for addition of two Matrices of same size.

Visual Presentation: Sample Solution:

C Code:

``````#include <stdio.h>

void main() {
int arr1, brr1, crr1, i, j, n;

// Prompt user for input
printf("------------------------------\n");
printf("Input the size of the square matrix (less than 5): ");
scanf("%d", &n);

// Input elements for the first matrix
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]);
}
}

// Input elements for the second matrix
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]);
}
}

// Display the first matrix
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]);
}

// Display the second matrix
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 sum of the matrices
for (i = 0; i < n; i++)
for (j = 0; j < n; j++)
crr1[i][j] = arr1[i][j] + brr1[i][j];

// Display the addition of two matrices
printf("\nThe Addition 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:

```Addition of two Matrices :
------------------------------
Input the size of the square matrix (less than 5): 2
Input elements in the first matrix :
element - , : 1
element - , : 2
element - , : 3
element - , : 4
Input elements in the second matrix :
element - , : 5
element - , : 6
element - , : 7
element - , : 8

The First matrix is :
1       2
3       4
The Second matrix is :
5       6
7       8
The Addition of two matrix is :
6       8
10      12
```
