打印钻石字母图案的C语言程序

编写一个C语言程序，使用for循环打印钻石字母图案。

#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");
}

这是另一种写C程序的方法，显示字母的钻石图案。

#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语言例子使用一个while循环来打印字母的钻石图案。

#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");
}
