C++ Modules are a tooling opportunity. For example, a common implementation strategy for compilers is to save on disk the abstract semantics graph (ASG) obtained from elaborating a module interface (exported), to be reused later when that module is consumed (imported). That ASG, an intermediate representation, saves the compiler from repeated work in common scenarios, therefore helps achieve substantial reduction in compilation time. In essence, ISO C++ compilers are practically compelled to acknowledge representations of C++ program fragments other than character streams stored in source files. It is all too tempting to view these ASGs as mere build artifact curiosities. If N compilers, on a given platform, decide to use N different on-disk ASG representation formats then we face a severe problem of developer tools fragmentation. I present, in this talk, how the C++ community can avoid that problem: the desiggn and implementation of formal, compiler-neutral in-memory and persistent representations of C++ programs. These alternative representations allow tools to process C++ programs without needing to master or to replicate the dark art of C++ compiler construction. These representations are available either as open specification, or as C++ libraries. The application opportunities range from automated generation of bindings ("foreign function/data interface") to Just-In-Time compilation of interpreted C++ scripts, and beyond.
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. Vim, Sublime 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++.

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:
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.
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.

Summary: I explain how a graph can be represented in C++ using variousSTL containers and what are the pros and cons for each method. This is intended for people who are studying for technical job interviews.

In this article, we’ll take a look at using the isdigit() function in C/C++. This is a very simple way to check if any value is a digit or not. Let’s look at how to use this function, using some simple examples.

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.
