Using preprocessor directives. Instead of using a regularifstatement, functions can use the#ifpreprocessor directive that selectively compiles a function after evaluating its branch conditions. This approach avoids code duplication but reduces the performance benefits of precompiled Metal shading language cod...
However, there are a few shortcomings of preprocessor macros that tip the scales in favor of inline functions in C++. These are: Macros can not access private class members: This inhibits their ability to encapsulate data and thereby compromises data privacy. Macros lack type checking: This can...

What is pseudocode and how is it useful at the software design stage? 4. What is a function “prototype” and where can it be found in a C program? 5. How much data can be input to and output from a function? 6. What is the purpose of the preprocessor in the C program compilatio...

You can also use the Microsoft-specific _tmain, which is a preprocessor macro defined in tchar.h. _tmain resolves to main unless _UNICODE is defined. In that case, _tmain resolves to wmain. The _tmain macro and other macros that begin with _t are useful for code that must build ...
Repeat Example 3.10, but this time, define the array size at the beginning of the program using the #define preprocessor operator and then pass both the array and its size to the function. Solution 3.11 The required program listing is shown in Figure 3.11. Here, the array size is defined ...

However, the approach a programmer uses is not always the most efficient or cleanest set of code. This guide provides standards for coding business functions that are efficient and easier to maintain. The following sections are covered in this guide: - Design Standards - Standard Header and ...
The namespace that delegate is defined in is configurable. By default, it is defined in namespace cpp; however this can be toggled by defining the preprocessor symbol DELEGATE_NAMESPACE to be the name of the desired namespace.This could be done either through a #define preprocessor directive:...
