表生成器兼更容易理解的打表:
#include <cstdio>
#include <cstring>
const char dic[]="  1234567890-=QWERTYUIOP[]\\ASDFGHJKL;'ZXCVBNM,./";
char str[1000];
int main()

	int i,j,l,l2=strlen(dic);
	while (gets(str)!=NULL)

		for (i=0;i<l;i++)
		{
			for (j=1;str[i]!=dic[j] && j<l2;j++);
			if (j<l2)
				printf("%c",dic[j-1]);
			else
				printf(" ");

		printf("\n");
