打印金字塔字母图案的C语言程序

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");
}

这个C语言例子使用while循环来打印金字塔的字母图案。

#include <stdio.h>.

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


printf("Enter Pyramid of Alphabets 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 Pyramid of Alphabets Rows = 16
