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.
Pictorial Presentation:

Sample Solution:
C Code:
#include <stdio.h>
void main()
{
int arr1[3][3],i,j;
printf("\n\nRead a 2D array of size 3x3 and print the matrix :\n");
printf("------------------------------------------------------\n");
/* Stored values into the array*/
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]);
}
}
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
