How to use #ifdef and #ifndef to check if an identifier has been defined
#ifdef, #ifndef and #endif are preprocessor directives which allow us to check wether or not a value has already been defined using the #define directive. This can be useful when you’re including files that may already have the same value defined using #define. Here’s an example that defines the value Whidbey only if it wasn’t defined before: #ifndef Whidbey#define Whidbey#endif Similarly, what’s between #ifdef and #endif is compiled […]

How to convert C++ variables to other data types using casting
There are several ways to convert C++ variables.Here is one method of converting an integer variable to a bool (boolean) variable: int MyInteger = 0;bool MyBool = (bool)MyInteger; And here is another way: int MyInteger = 0;bool MyBool = static_cast<bool>(MyInteger); In both cases, after the casting has been made, MyBool will contain the value false (since MyInteger was 0). If MyInteger was 1 or any other number […]
