Description

The Conversion Library improves program safety and clarity by performing otherwise messy conversions. It includes cast-style function templates designed to complement the C++ Standard's built-in casts.

To reduce coupling, particularly to standard library IOStreams, the Boost Conversion Library is supplied by several headers:

  1. The boost/polymorphic_cast.hpp header provides polymorphic_cast<> and polymorphic_downcast<> to perform safe casting between polymorphic types.
  2. The boost/polymorphic_pointer_cast.hpp header provides polymorphic_pointer_cast<> and polymorphic_pointer_downcast<>
  3. The boost/implicit_cast.hpp header provides implicit_cast<> to perform implicit casts only (no down-cast, no void*->T*, no U->T if T has only explicit constructors for U).
  4. The boost/lexical_cast.hpp header provides lexical_cast<> general literal text conversions, such as an int represented as a string, or vice-versa.

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.

A handy reference to C conversion specifiers and modifiers

In this post I want to create a helpful reference for all the C conversion specifiers you can use, commonly with printf(), scanf() and similar I/O functions.

C# Source Generators to boost performance in .NET 5

A new C# compiler feature that inspects code and generates additional source files promises to improve performance in a number of scenarios.

Microsoft has introduced a preview of a C# compiler capability called Source Generators that can inspect a program and generate source files that can be added to a compilation. Microsoft says Source Generators can improve performance in a number of scenarios.

Introduced April 29, a Source Generator is a piece of code (a .NET Standard 2.0 assembly) that runs during compilation and can inspect a program to produce additional files that are compiled together with the rest of the code.

Loops in C++ | For, While, and Do While Loops in C++

In this Video We are going to see how to use Loops in C++. We will see How to use For, While, and Do While Loops in C++.
C++ is general purpose, compiled, object-oriented programming language and its concepts served as the basis for several other languages such as Java, Python, Ruby, Perl etc.
