Then you can include your own header in the C++ program without issue or tricks.You could compile the code which uses the header as C, then just link it together with your C++ object files.

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.
