Initial Support For C++20 Ranges

We are happy to announce that Visual Studio 2019 version 16.6 contains the first user-visible pieces of C++20 Ranges support. We’ve been working on support machinery for a few releases now, but in this release the tip of the iceberg has finally broken the surface of the water and there are now some tools available for users. The Ranges implementation critically depends on C++ Concepts, and as such is usable with both MSVC and Clang in their C++20 Preview modes but not yet well-supported by IntelliSense. (Don’t worry, we’ll have proper IntelliSense support soon.)

What’s Available?

  • The standard library concepts in <concepts> have been shipping in MSVC since version 16.3. This includes the customization point std::ranges::swap, which is like a smarter std::swap that does “the using bit” for you.
  • The first batch of Range algorithms in <algorithm>:
  • copycopy_n, and copy_if
  • all_ofany_of, and none_of
  • findfind_if, and find_if_not
  • count and count_if
  • for_each and for_each_n
  • equal and mismatch

There’s a brief demo of some of these facilities in Mahmoud Saleh’s talk from the Pure Virtual C++ conference (with code available).

How to Run C/C++ in Sublime Text?

C and C++ are the most powerful programming language in the world. Most of the super fast and complex libraries and algorithms are written in C or C++. Most powerful Kernel programs are also written in C. So, there is no way to skip it.

In programming competitions, most programmers prefer to write code in C or C++. Tourist is considered the worlds top programming contestant of all ages who write code in C++.

During programming competitions, programmers prefer to use a lightweight editor to focus on coding and algorithm designing. VimSublime Text, and Notepad++ are the most common editors for us. Apart from the competition, many software developers and professionals love to use Sublime Text just because of its flexibility.

I have discussed the steps we need to complete in this blog post before running a C/C++ code in Sublime Text. We will take the inputs from an input file and print outputs to an output file without using freopen file related functions in C/C++.

Dicey Issues in C/C++

If you are familiar with C/C++then you must have come across some unusual things and if you haven’t, then you are about to. The below codes are checked twice before adding, so feel free to share this article with your friends. The following displays some of the issues:

  1. Using multiple variables in the print function
  2. Comparing Signed integer with unsigned integer
  3. Putting a semicolon at the end of the loop statement
  4. C preprocessor doesn’t need a semicolon
  5. Size of the string matters
  6. Macros and equations aren’t good friends
  7. Never compare Floating data type with double data type
  8. Arrays have a boundary
  9. Character constants are different from string literals
  10. Difference between single(=) and double(==) equal signs.

The below code generates no error since a print function can take any number of inputs but creates a mismatch with the variables. The print function is used to display characters, strings, integers, float, octal, and hexadecimal values onto the output screen. The format specifier is used to display the value of a variable.

  1. %d indicates Integer Format Specifier
  2. %f indicates Float Format Specifier
  3. %c indicates Character Format Specifier
  4. %s indicates String Format Specifier
  5. %u indicates Unsigned Integer Format Specifier
  6. %ld indicates Long Int Format Specifier

A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a non-negative integer in the range [0 to 4294967295]. The signed integer is represented in twos-complement notation. In the below code the signed integer will be converted to the maximum unsigned integer then compared with the unsigned integer.

Behind the compiler: 20 examples of C# code before and after compiling

Over years I have written many blog posts about C# and .NET that demonstrate also how things work internally and what C# compiler produces from the code we write. I have called these chapters usually as “Behind the compiler”. This post is growing list of my writings covering interesting findings about C# compiler work.
