C 语言打印金字塔字母图案程序

编写一个C语言程序，使用for循环打印金字塔字母图案。

#include <stdio.h>

int main()
{
	int rows;

	printf("Enter Pyramid of Alphabets Rows = ");
	scanf("%d", &rows);

	printf("Printing Pyramid Alphabets Pattern\n");

	int alphabet = 64;

	for (int i = 1; i <= rows; i++)
	{
		for (int j = 1; j <= rows - i; j++)
		{
			printf(" ");
		}
		for (int k = i; k > 0; k--)
		{
			printf("%c", alphabet + k);
		}
		for (int l = 2; l <= i; l++)
		{
			printf("%c", alphabet + l);
		}
		printf("\n");
	}
}

本示例使用while循环打印字母金字塔图案。

#include <stdio.h>

int main()
{
	int i, j, k, l, alphabet, rows;

	printf("Enter Rows = ");
	scanf("%d", &rows);

	printf("\n");

	alphabet = 64;
	i = 1;

	while (i <= rows)
	{
		j = 1;
		while (j <= rows - i)
		{
			printf(" ");
			j++;
		}

		k = i;
		while (k > 0)
		{
			printf("%c", alphabet + k);
			k--;
		}

		l = 2;
		while (l <= i)
		{
			printf("%c", alphabet + l);
			l++;
		}
		printf("\n");
		i++;
	}
}

Enter Rows = 16
