C Program to Print 2D Array Elements

Write a C program to print 2D array elements or two-dimensional array items using for loop. In this c example, the first for loop iterates rows, and the second loop iterates columns. Within the C for loop, we print the 2D array elements, and we insert a new line (printf(“\n”)) for each row iteration.

#include<stdio.h>
 
int main()
{
 	int rows, columns;
	
	int a[2][2] = {{10, 20}, {30, 70}};

	printf("\nPrinting the 2D Array\n");
 	for(int rows = 0; rows < 2; rows++)
  	{
  		for(int columns = 0; columns < 2; columns++)
  		{
  			printf("%d  ", a[rows][columns]);
		}
   		printf("\n");
  	}  	

 	return 0;
} 

This C program allows users to enter rows, columns, and the 2D array elements and prints those two dimensional array items.

#include<stdio.h>
 
int main()
{
 	int i, j, rows, columns;
  
 	printf("\nEnter 2D Array rows and columns =  ");
 	scanf("%d %d", &i, &j);
	
	int a[i][j];

 	printf("\nPlease Enter the 2D Array Elements \n");
 	for(rows = 0; rows < i; rows++)
  	{
   		for(columns = 0; columns < j; columns++)
    	{
      		scanf("%d", &a[rows][columns]);
    	}
  	}
	printf("\nPrinting the 2D Array\n");
 	for(rows = 0; rows < i; rows++)
  	{
  		for(columns = 0;columns < j; columns++)
  		{
  			printf("%d  ", a[rows][columns]);
		}
   		printf("\n");
  	}  	

 	return 0;
} 

Enter 2D Array rows and columns =  3 3

Please Enter the 2D Array Elements 
11 22 33 44 55 66 77 88 99

C program to print 2D array elements using a while loop

#include <stdio.h>

int main()
{
	int i, j, rows, columns;

	printf("\nEnter 2D Array rows and columns =  ");
	scanf("%d %d", &i, &j);

	int a[i][j];

	printf("\nPlease Enter the 2D Array Elements \n");
	rows = 0;
	while (rows < i)
	{
		columns = 0;
		while (columns < j)
		{
			scanf("%d", &a[rows][columns]);
			columns++;
		}
		rows++;
	}
	printf("\nPrinting the 2D Array\n");
	rows = 0;
	while (rows < i)
	{
		columns = 0;
		while (columns < j)
		{
			printf("%d  ", a[rows][columns]);
			columns++;
		}
		printf("\n");
		rows++;
	}
}

Enter 2D Array rows and columns =  3 4

Please Enter the 2D Array Elements 
10 20 30 40
50 60 70 80
90 11 22 33
