以直角三角形打印连续列号的C语言程序

编写一个C语言程序，使用for循环打印右三角模式的连续列数字。

#include <stdio.h>

int main() { i, j, rows, k = 1;

printf("Enter Right Triangle Consecutive Col Nums Pattern Rows = ");
scanf("%d",&rows);

printf("Consecutive Numbers in Right Triangle Column Pattern\\n"); 

for (i = 1; i <= rows; i++ ) 
{
	for (j = 1 ; j <= i; j++ ) 	
	{
		printf("%d ", k++);
	}
	printf("\\n");
}

return 0;

这个C语言例子使用一个while循环来打印连续列号的直角三角形图案。

#include <stdio.h>

int main() { int i = 1, j, rows, k = 1;

printf("Enter Right Triangle Consecutive Col Nums Pattern Rows = ");
scanf("%d",&rows);

printf("Consecutive Numbers in Right Triangle Column Pattern\\n"); 

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

return 0;

C 用do while循环显示直角三角形中连续列数的程序。

#include <stdio.h>

int main() { int i = 1, j, rows, k = 1;

printf("Enter Right Triangle Consecutive Col Nums Pattern Rows = ");
scanf("%d",&rows);

printf("Consecutive Numbers in Right Triangle Column Pattern\\n"); 

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

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

} while (++i <= rows );

return 0;
