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
