The #if ... #else preprocessor directive example/program: Here, we will learn how the #if ... #else directive works in C programming language.
C++ If-Else Statement - Learn how to use if-else statements in C++ programming to handle conditional logic effectively with examples.
Preprocessor operators See also The #if directive, with the #elif, #else, and #endif directives, controls compilation of portions of a source file. If the expression you write (after the #if) has a nonzero value, the line group immediately following the #if directive is k...

All identifiers used in the controlling expression of #if or #elif preprocessing directives shall be #define'd before evaluation. Rationale If attempt to use a macro identifier in a preprocessing directive, and you have not defined that identifier, then the preprocessor assumes that it has a valu...
A case pattern may not be expressive enough to specify the condition for the execution of the switch section. In such a case, you can use acase guard. That is an additional condition that must be satisfied together with a matched pattern. A case guard must be a Boolean expression. You...

Swift never had a preprocessor, no one took anything away. In fact, Apple has been adding more preprocessor-like constructs over the years. That being said, I do wish Apple would add more ways to conditionally compile out code in Swift, particularly how you can do with macros in C/C++,...
I see similar increase in time from a given line with something like G(I)=A(I,J,K)*X Combining the arrays into a single array may be possible but its not simple. would the preprocessor command work if placed within the module? or would it have to be in each r...
