利用ASCII码返回大小写字母

JAVA版:

class More
{
	public static void main(String args[])
	{
		char a = 'a';
		int i = 0;
		
		System.out.println("打印26个大小写字母:");
		
		for (; i < 26; i++)
		{
			System.out.print((char)(a + i));
		}
		
		System.out.println("");
		a = 'A';
		i = 0;
		
		for (; i < 26; i ++)
		{	
			System.out.print((char)(a + i));
		}
	}
}

 C语言版:

#include <stdio.h>

int main()
{
	char a = 'a';
	int i = 0;
	
	printf("打印大小写字母:\n");

	for (; i < 26; i++)
	{
		printf("%c", a + i);
	}
	
	printf("\n");
	a = 'A';
	i = 0;

	for (; i < 26; i++)
	{
		printf("%c", a + i);
	}

	printf("\n");
}
