Question

vc++6.0中怎么使用布尔型

/*Program 3_7 Confused recruition policy*/
#include <stdio.h>
/*#include <stdbool.h>*/
int main(void)
{
int age=0; /*Age of the applicant*/
int college=0; /*Code for college attended*/
int subject=0; /*Code for subject studied*/
bool interview=false; /*True for accept,false for reject*/
/*Get data on the applicant*/
printf("\nWhat college?1 for Harvard,2 for Yale,3 for other:");
scanf("%d",&college);
printf("\nWhat subject?1 for chemistry,2 for economies,3 for other:");
scanf("%d",&subject);
printf("\nHow old is the applicant?");
scanf("%d",&age);
/*Check out the applicant*/
if((age>25&&subject==1)&&(college==3||college==1))
interview=true;
if(college==2&&subject==1)
interview=true;
if(college==1&&subject==2&&(age<28))
interview=true;
if(college==2&&(subject==2||subject==3)&&age>25)
interview=true;
/*Output decision for interview*/
if(interview)
printf("\n\nGive 'en an interview.");
else
printf("\n\nReject 'em.");
return 0;
}

开始说找不到头文件stdbool.h，我注释掉了以后，错误是bool,false,true都没定义
自己找了个下面的stdbool.h，
/*
stdbool.h

-- Boolean type and values
(substitute for missing C99 standard header)

public-domain implementation from [EMAIL PROTECTED]

implements subclause 7.16 of ISO/IEC 9899:1999 (E)
*/

#ifndef __bool_true_false_are_defined
#define __bool_true_false_are_defined 1

/* program is allowed to contain its own definitions, so ... */
#undef bool
#undef true
#undef false

#if __STDC_VERSION__ < 199901
typedef int _Bool
#endif

#define bool _Bool
#define true 1
#define false 0

#endif /* !defined(__bool_true_false_are_defined) */

错误是
error C2054: expected '(' to follow '_Bool'
error C2085: 'main' : not in formal parameter list
error C2143: syntax error : missing ';' before '{'
敲代码的时候确实变蓝色了，就是通不过编译，难道是vc的问题？
加上using namespace std;也有错误

Answer 1

#include <stdio.h>
/*#include <stdbool.h>*/
using namespace std;//!!!!!!
int main(void)

Answer 2

貌似VC 都没有stdbool。。。自己定义咯，不过好像很麻烦，我是菜鸟，帮不了你了。

Answer 3

VC中True，false等都是关键字来的，是不是你的VC装的有问题？
