我换成英文版的，但我做2.5时输入
#include <iostream.h>
int main(void)
{
        bool b:
        bool a;
        cin>>a;
        cin>>b;
        cout<<"!a="<<!a<<endl;
        cout<<"a&&b"<<(a&&b)<<endl;
        cout<<"a||b"<<(a||b)<<endl;
        return 0;
}
出--------------------Configuration: test - Win32 Debug--------------------
Compiling...
test.cpp
d:\代码\test\test.cpp(13) : fatal error C1010: unexpected end of file while looking for precompiled header directive
Error executing cl.exe.

test.exe - 1 error(s), 0 warning(s)

超级小白

你在文件第一行写上#include   "stdafx.h" 了么？

还有bool b后面应该是分号，而不是冒号

我照你们说的改了，但还有错误
#include "stadfx.h"
#include <iostream.h>
int main(void)
{
        bool b;
        bool a;
        cin>>a;
        cin>>b;
        cout<<"!a="<<!a<<endl;
        cout<<"a&&b"<<(a&&b)<<endl;
        cout<<"a||b"<<(a||b)<<endl;
        return 0;
}
出--------------------Configuration: test - Win32 Debug--------------------

stadfx.h  应该是stdafx。h

小病

也错的#include "stdafx.h"
#include <iostream.h>
int main(void)
{
        bool b;
        bool a;
        cin>>a;
        cin>>b;
        cout<<"!a="<<!a<<endl;
        cout<<"a&&b"<<(a&&b)<<endl;
        cout<<"a||b"<<(a||b)<<endl;
        return 0;
}--------------------Configuration: test - Win32 Debug--------------------

书上的与CD中的演示有区别：
#include <iostream.h>
int main(void)
{
        bool b;
        bool a;
        cin>>a;——————应为a=true;
        cin>>b;——————应为b=false;
        cout<<"!a="<<!a<<endl;
        cout<<"a&&b"<<(a&&b)<<endl;
        cout<<"a||b"<<(a||b)<<endl;
        return 0;
改了之后我的VC才通过
