C 语言打印字母菱形图案程序

编写一个C语言程序，使用for循环打印字母菱形图案。

#include <stdio.h>

int main()
{
	int i, j, k, rows, alphabet = 64;

	printf("Enter Diamond Pattern of Alphabets Rows = ");
	scanf("%d", &rows);
		
	printf("Printing Diamond Alphabets Pattern\n");
	for (i = 1 ; i <= rows; i++ ) 
	{
		for (j = 1 ; j <= rows - i; j++ ) 
		{
			printf(" ");	
		}
		for (k = 1 ; k <= i * 2 - 1; k++ ) 
		{
			printf("%c", alphabet + k);
		}
		printf("\n");
	}
		
	for (i = rows - 1 ; i > 0; i-- ) 
	{
		for (j = 1 ; j <= rows - i; j++ ) 
		{
			printf(" ");
		}
		for (k = 1 ; k <= i * 2 - 1; k++ ) 
		{
			printf("%c", alphabet + k);
		}
		printf("\n");
	}
}

这是另一种编写C语言程序以显示字母菱形图案的方法。

#include <stdio.h>

int main()
{
	int i, j, k, rows, alphabet = 65;

	printf("Enter Diamond Pattern of Alphabets Rows = ");
	scanf("%d", &rows);
		
	printf("Printing Diamond Alphabets Pattern\n");

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

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

Enter Diamond Pattern of Alphabets Rows = 10

        A B C 
       A B C D 
      A B C D E 
     A B C D E F 
    A B C D E F G 
   A B C D E F G H 
  A B C D E F G H I 
 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 

这个C 语言示例使用 while 循环打印字母菱形图案。

#include <stdio.h>

int main()
{
	int i, j, k, l, rows, alphabet = 64;

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

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

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

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