In Visual C++ 5.0 and later, bool is implemented as a built-in type with a size of 1 byte. That means that for Visual C++ 4.2, a call of sizeof(bool) yields 4, while in Visual C++ 5.0 and later, the same call yields 1. This can cause memory corruption problems if you have ...
This keyword is a built-in type. A variable of this type can have values true and false. Conditional expressions have the type bool and so have values of type bool. For example, i != 0 now has true or false depending on the value of i.Visual...
C++中的bool是一种基本数据类型,用于表示逻辑值,即真(true)或假(false)。bool类型只有两个可能的取值,即true和false。 bool类型在C++中通常用于条件判断和逻辑运算。在条件判断语句中,bool类型的变量可以作为判断条件,根据条件的真假执行相应的代码块。在逻辑运算中,bool类型的变量可以进行与(&&)、或(||)、非(!)...
