C语言 例程

stdio;

case 'n"please input second letter\W'please input the first letter of someday\break;n";S')
printf("
void main(){
char letter;Y'
case 'friday\break，请高手帮忙调一下，不胜感激:printf("
default;);break;) printf("sunday\){
switch (letter){
case ');h'
else if ((letter=getchar())=='saturday\
while ((letter=getchar());a';
case 'F'
printf(");
if((letter=getchar())=='
}
}
}

有错误:printf("n");monday\);)
printf("data error\data error\n");T'data error\break;): printf(");u'n".h"

我这调试是没问题的..如果你用Dev c++的话
不要用void main
改成int main
并添加一个返回值,如果是VC的话不用
标准c++必须要有返回值

推荐：

下载一个win-tc

这样不但运行环境有了

而且里面还自带了教程

#include void main() { char letter; printf("please input the first letter of someday\n"); while ((letter=getchar())!='Y') { switch (letter) { case 'S':printf("please input second letter\n"); letter=getchar(); letter=getchar(); if(letter=='a') { printf("saturday\n"); break; } else if (letter=='u') { printf("sunday\n"); break; } else printf("data error\n"); break; case 'F':printf("friday\n");break; case 'M':printf("monday\n");break; case 'T':printf("please input second letter\n"); letter=getchar(); letter=getchar(); if(letter=='u') { printf("tuesday\n"); break; } else if (letter=='h') { printf("thursday\n"); break; } else printf("data error\n");break; case 'W':printf("wednesday\n");break; default: printf("data error\n"); } letter=getchar(); } } 这样就行了
