C 语言打印二维数组元素程序

编写一个 C 程序，使用 for 循环打印二维数组元素或二维数组项。在此 C 示例中，第一个 for 循环迭代行，第二个循环迭代列。在 for 循环内，我们打印二维数组元素，并在每次行迭代时插入一个新行（printf(“\n”))。

#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;
} 

此 程序 允许用户输入行、列和二维数组元素，并打印这些二维数组项。

#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

77  88  99 

使用 while 循环打印二维数组元素的 C 程序

#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
