以正弦波模式打印直角三角形数字的C程序

编写一个C语言程序，使用for循环打印正弦波模式下的直角三角形数字。

#include <stdio.h>

int main() { int rows;

printf("Enter Right Traingle of Numbers in Sine Wave Rows = ");
scanf("%d", &rows);

printf("Right Traingle of Numbers in Sine Wave format\\n");

for (int i = 1; i <= rows; i++)
{
	printf("%d ", i);
	int num = i;

	for (int j = 1; j < i; j++)
	{
		if (j % 2 != 0)
		{
			printf("%d ", (num + ((2 \* (rows - i + 1)) - 1)));
			num = num + ((2 \* (rows - i + 1)) - 1);
		}
		else
		{
			printf("%d ", (num + 2 \* (i - j)));
			num = num + 2 \* (i - j);
		}
	}
	printf("\\n");
}

C程序的另一种写法是以直角三角形的形式显示数字的正弦波模式。

#include <stdio.h>

int main() { int rows;

printf("Enter Right Traingle of Numbers in Sine Wave Rows = ");
scanf("%d", &rows);

printf("Right Traingle of Numbers in Sine Wave Pattern\\n");

for (int i = 0; i < rows; i++)
{
	for (int j = 0; j <= i; j++)
	{
		if (j % 2 == 0)
		{
			printf("%d ", 1 + j \* rows - (j - 1) \* j / 2 + i - j);
		}
		else
		{
			printf("%d ", 1 + j \* rows - (j - 1) \* j / 2 + rows - i - 1);
		}
	}
	printf("\\n");
}

Enter Right Traingle of Numbers in Sine Wave Rows = 13

这个C语言例子使用一个while循环来打印正弦波格式的数字的右三角图案。

#include <stdio.h>

int main() { int rows;

printf("Enter Right Traingle of Numbers in Sine Wave Rows = ");
scanf("%d", &rows);

printf("Right Traingle of Numbers in Sine Wave Pattern\\n");
int num, j, i = 1;

while (i <= rows)
{
	printf("%d ", i);
	num = i;
	j = 1;

	while (j < i)
	{
		if (j % 2 != 0)
		{
			printf("%d ", num + ((2 \* (rows - i + 1)) - 1));
			num = num + ((2 \* (rows - i + 1)) - 1);
		}
		else
		{
			printf("%d ", num + 2 \* (i - j));
			num = num + 2 \* (i - j);
		}
		j++;
	}
	printf("\\n");
	i++;
}
