打印K字形数字图案的C语言程序

编写一个C语言程序，使用for循环打印K形数字模式。

#include <stdio.h>

int main() { i, j, rows;

printf("Enter K Shape Numbers Pattern Rows = ");
scanf("%d",&rows);

printf("\\nThe K Shape Numbers Pattern\\n"); 

for (i = rows; i >= 1; i-- ) 
{
	for (j = 1 ; j <= i; j++ ) 	
	{
		printf("%d ", j);
	}
	printf("\\n");
}
	
for (i = 2 ; i <= rows; i++ ) 
{
	for (j = 1; j <= i; j++ ) 	
	{
		printf("%d ", j);
	}
	printf("\\n");
}
return 0;

#include <stdio.h>

int main() { i, j, rows;

printf("Enter K Shape Numbers Pattern Rows = ");
scanf("%d",&rows);

printf("\\nThe K Shape Numbers Pattern\\n"); 
i = rows;

while( i >= 1 ) 
{
	j = 1 ;
	while( j <= i ) 	
	{
		printf("%d ", j);
		j++;
	}
	printf("\\n");
	i--;
}

i = 2 ;
while ( i <= rows ) 
{
	j = 1;
	while ( j <= i) 	
	{
		printf("%d ", j);
		j++;
	}
	printf("\\n");
	i++;
}
return 0;

Enter K Shape Numbers Pattern Rows = 11

C程序使用do while循环显示一个K形数字图案。

#include <stdio.h>

int main() { i, j, rows;

printf("Enter K Shape Numbers Pattern Rows = ");
scanf("%d",&rows);

printf("\\nThe K Shape Numbers Pattern\\n"); 
i = rows;

do
{
	j = 1 ;
	do 	
	{
		printf("%d ", j);

	} while( ++j <= i );
	printf("\\n");

} while( --i >= 1 );

i = 2 ;
do 
{
	j = 1;
	do 	
	{
		printf("%d ", j);

	} while ( ++j <= i);
	printf("\\n");

} while ( ++i <= rows );
return 0;
