# C Exercises: Read a 2D array of size 3x3 and print the matrix

## C Array: Exercise-18 with Solution

Write a program in C for a 2D array of size 3x3 and print the matrix.

Visual Presentation:

Sample Solution:

C Code:

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

void main() {
int arr1[3][3], i, j;

// Prompt user for input
printf("\n\nRead a 2D array of size 3x3 and print the matrix :\n");
printf("------------------------------------------------------\n");

// Input values for the matrix
printf("Input elements in the matrix :\n");
for (i = 0; i < 3; i++) {
for (j = 0; j < 3; j++) {
printf("element - [%d],[%d] : ", i, j);
scanf("%d", &arr1[i][j]);
}
}

// Display the matrix
printf("\nThe matrix is : \n");
for (i = 0; i < 3; i++) {
printf("\n");
for (j = 0; j < 3; j++)
printf("%d\t", arr1[i][j]);
}
printf("\n\n");
}
```
```

Sample Output:

```Read a 2D array of size 3x3 and print the matrix :
------------------------------------------------------
Input elements in the matrix :
element - [0],[0] : 1
element - [0],[1] : 2
element - [0],[2] : 3
element - [1],[0] : 4
element - [1],[1] : 5
element - [1],[2] : 6
element - [2],[0] : 7
element - [2],[1] : 8
element - [2],[2] : 9

The matrix is :

1       2       3
4       5       6
7       8       9
```
