打印倒置的直角三角形字母图案的C语言程序

编写一个C语言程序，使用for循环打印倒置的直角三角形字母图案。

#include <stdio.h

int main() { int rows;

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

printf("Printing Inverted Right Triangle Alphabets Pattern\\n");
int alphabet = 65;

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

#include <stdio.h>.

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

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

printf("Printing Inverted Right Triangle Alphabets Pattern\\n");
alphabet = 65;
i = rows - 1;

while (i >= 0)
{
	j = 0;
	while (j <= i)
	{
		printf("%c ", alphabet + j);
		j++;
	}
	printf("\\n");
	i--;
}

Enter Inverted Right Triangle of Alphabets Rows = 13
Printing Inverted Right Triangle Alphabets Pattern
A B C D E F G H I J K L M 
A B C D E F G H I J K L 
A B C D E F G H I J K 
A B C D E F G H I J 
A B C D E F G H I 
A B C D E F G H 
A B C D E F G 
A B C D E F 
A B C D E 
A B C D 
A B C 
A B 
A 

在这个C模式的例子中，我们用do while循环来显示字母的右三角。

#include <stdio.h>.

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

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

printf("Printing Inverted Right Triangle Alphabets Pattern\\n");

alphabet = 65;
i = rows - 1;

do
{
	j = 0;
	do
	{
		printf("%c ", alphabet + j);

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

} while (--i >= 0);

Enter Inverted Right Triangle of Alphabets Rows = 15
