no c programs support bool when it is not explicitly defined. To use bool you must make C++ programs with .C (c in upper case) or .cpp exetnsion. P.S. Someone sent to me a mail. If you have a question please put it in the forum. I accept mails, but what is the forum for?
To perform logical operations with values of thebooltype, useBoolean logicaloperators. Thebooltype is the result type ofcomparisonandequalityoperators. Aboolexpression can be a controlling conditional expression in theif,do,while, andforstatements and in theconditional operator?:. ...
int a = 5; int b = a + 2; //OK bool test = true; // Error. Operator '+' cannot be applied to operands of type 'int' and 'bool'. int c = a + test; Note C and C++ developers, notice that in C#, bool is not convertible to int. The compiler embeds the type information...

and allow conversions such as the conversions between numerical types (short to int, int to float, double to int...), to or from bool, and some pointer conversions. Some of these conversionsmay imply a loss of precision, which the compiler can signal with a warning. This can be avoided...

Conversions to unsigned integer types other than _Bool Integer values are always preserved if they are within the range of the new unsigned type—in other words, if they are between 0 and Utype_MAX, where Utype_MAX is the greatest value that can be represented by unsigned type. For values...
