在C语言中如何使用bool类型

1.添加头文件#include stdio.h和#include windows.h。




2.在主函数里定义一个布尔类型变量，写bool judge = false;




3.换行写printf(%dn,judge);该语句，表示输出布尔变量(C语言里不能直接输出布尔值的false和true，只能用整数0和1代替)。




4.点击叹号运行。



 
代码清单：
#include stdafx.h
#include stdio.h
#include windows.h
 
void main()
{
 bool judge=false;
 printf(%dn,judge);
}
