     It sounds like you are asking about #if which skips sections of code based on compiler settings.

     Microsoft's documentation on the feature is located on MSDN note that this link may contain compiler specific rules (I didn't read through all of it).

   • define a program section in C code (GCC)

     Top Answer

     Answered Mar 23, 2013 · 22 votes

     The C standard doesn't say anything about "sections" in the sense that you mean, so you'll need to use extensions specific to your compiler.

     With GCC, you will want to use the section attribute:

     extern void foobar(void) __attribute__((section("bar")));-

     There is some limited documentation here, including a warning:

     Some file formats do not support arbitrary sections so the section attribute is not available on all platforms. If you need to map the entire contents of a module to a particular section, consider using the facilities of the linker instead.

   • C++, comment in a multi-line piece of code

     int Func(int a, // comment int b, // comment int c // comment ) ...-

     Is converted to

     int Func(int a, int b, int c ) ...

     during the third phase of translation. If you wanted a single line equivelent before the translation phase happens then you need to use /* */ like

     int Func(int a /*comment 1*/, int b /*comment 2*/, int c /*comment 3*/ ) ...

   • `#define` a very large number in c++ source code

     Top Answer

     Answered May 23, 2017 · 2 votes

     You can define a constexpr function:

     constexpr size_t MAX_ARR_SIZE(){ return pow(10, 15); }-

     That way you can do even more complex calculations in compile time.

     Then use it as array<int, MAX_ARR_SIZE()> myArr; it will be evaluated in compile time.

     Also like it was already mentioned, you probably won't be able to allocate that size on the stack.

     EDIT:

     I have a fault here, since pow itself is not constexpr you can't use it, but it's solvable, for example use ipow as discussed here: c++11 fast constexpr integer powers

     here is the function quote:

     constexpr int64_t ipow(int64_t base, int exp, int64_t result = 1) { return exp < 1 ? result : ipow(base*base, exp/2, (exp % 2) ? result*base : result);}-

     simply change MAX_ARR_SIZE() to:

     constexpr size_t MAX_ARR_SIZE(){ return ipow(10, 15); }-

   • // Comment in C++ vs /* */ in C

     Top Answer

     Answered Aug 07, 2014 · 2 votes

     It is a matter of taste and habits.

     Line comments

     // like this-

     are shorter to type (and acceptable both in C99 code and in C++03 code), and they can be "nested"

     // nested // line // comment

     In C or C++ block comments

     /* like that block comment */

     can be smaller (or much larger) than a line

     if (/*strange*/ some_test()) {

     But they cannot be nested:

     /* WRONG /* NESTED COMMENT */ // is ended here but you may want them to nest */

     Notice that many editors (e.g. emacs) or IDEs are aligning/reformatting/highlighting comments. Most of them (and also GNU indent) are able to deal efficiently with

     /************************************** * some boxed block comment * like this **************************************/

     PS. In Ocaml some (* ... *) comments can be nested

   No, you can't. Comments are removed from the code before any processing of preprocessing directives begin. For this reason you can't include comment into a macro. Also, any attempts to "form" a comment later by using any macro trickery are not guaranteed to work.

   In C, a single line comment starts with //symbol. It starts and ends in the same line. For example, Output In the above example, we have used two single-line comments: 1. // create integer variable 2. // print the age variable We can also use the single line comment along with the code.

   In C programming, there is another type of comment that allows us to comment on multiple lines at once, they are multi-line comments. To write multi-line comments, we use the /*....*/symbol. For example, Output In this type of comment, the C compiler ignores everything from /* to */.

   While debugging there might be situations where we don't want some part of the code. For example, In the program below, suppose we don't need data related to height. So, instead of removing the code related to height, we can simply convert them into comments. Here, the code throws an error because we have not defined a productvariable. We can comme...

   We should use comments for the following reasons: 1. Comments make our code readable for future reference. 2. Comments are used for debugging purposes. 3. We can use comments for code collaboration as it helps peer developers to understand our code. Next, we will be learning in detail about C Variables, constants and literals.
