打印K字形字母图案的C语言程序

编写一个C语言程序，使用for循环打印K形字母图案。

#include <stdio.h

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

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

printf("\\nThe K Shape Alphabets/Characters Pattern\\n"); 

for (i = rows - 1; i >= 0; i-- ) 
{
	alphabet = 65;
	for (j = 0 ; j <= i; j++ ) 	
	{
		printf("%c ", alphabet + j);
	}
	printf("\\n");
}
	
for (i = 1 ; i < rows; i++ ) 
{
	alphabet = 65;
	for (j = 0 ; j <= i; j++ ) 	
	{
		printf("%c ", alphabet + j);
	}
	printf("\\n");
}
return 0;

}

#include <stdio.h>.

int main() { i, j, rows, alphabet;
printf("Enter K Shape Alphabets Pattern Rows = ");
scanf("%d",&rows);

printf("\\nThe K Shape Alphabets/Characters Pattern\\n");

i = rows - 1;

while (i >= 0 ) 
{
	alphabet = 65;
	j = 0 ;
	while ( j <= i) 	
	{
		printf("%c ", alphabet + j);
		j++;
	}
	printf("\\n");
	i--;
}
	
i = 1 ;
while ( i < rows ) 
{
	alphabet = 65;
	j = 0 ;
	while ( j <= i ) 	
	{
		printf("%c ", alphabet + j);
		j++;
	}
	printf("\\n");
	i++;
} 
return 0;

}

Enter K Shape Alphabets Pattern Rows = 8

C 程序使用do while循环来显示一个K形字母图案。

#include <stdio.h>.

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


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

printf("\\nThe K Shape Alphabets/Characters Pattern\\n");

i = rows - 1;

do
{
	alphabet = 65;
	j = 0 ;
	do	
	{
		printf("%c ", alphabet + j);

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

} while (--i >= 0 );
	
i = 1 ;
do 
{
	alphabet = 65;
	j = 0 ;
	do	
	{
		printf("%c ", alphabet + j);

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

} while ( ++i < rows );
return 0;

Enter K Shape Alphabets Pattern Rows = 12
