Use these new features using #include at the top of your program.stdbool.h also defines constants 'true' and 'false', with value 1 and 0 respectively.Variables can now be declared of type 'bool'.( Recall that C interprets any non-zero as true, i.e. Attempting to store anything else in a _Bool stores a 1._Bool is an unsigned integer, that can only be assigned the values 0 or 1.The type 'bool' is the same as a newly defined type '_Bool'.C99 provides a new header, stdbool.h, that defines some new helpful types and constants:.Today it is better to use const int instead of #define:.In the old days, this was done using #define:.To make life easier, C Programmers typically define the terms 'true' and 'false' to have values 1 and 0 respectively.For interpretation, Zero is interpreted as false and anything non-zero is interpreted as true.Zero is used to represent false, and One is used to represent true.C does not have boolean data types, and normally uses integers for boolean testing.A true boolean data type could be used for storing logical values, and would only have two legal values - 'true', and 'false'.C Programming Course Notes - Decisions and BranchingД«oolean Variables and Data Type ( or lack thereof in C )
