The technical work on C++20 was finished in January 2020, and is now being pushed through ISO certification.
This presentation gives an overview of (almost) all new features in both the language and the Standard Library. Some more exotic features will be left out. New language features include modules, coroutines, concepts, templated lambdas, constexpr changes, designated initializers, the spaceship operator, string literals as template parameters, feature test macros, conditional explicit, immediate functions, and more.
The second part of the session discusses the changes to the Standard Library. This includes topics such as ranges, atomic smart pointers, cancellable threads, a synchronization library, calendars, time zones, span, a formatting library, features test macros, and more.
The material is mostly the same as the “C++20: What’s in it for you?” session from CppCon 2019, but it has been updated with the final standard. If you want a complete overview of all C++20 features, including references to other more deep-dive sessions at CppCon 2020 on certain topics, then this session is for you.

In this article, we’ll take a look at using fread() in C/C++.
The fread() function is very useful if you want to store the contents of reading a file into a buffer. Let’s take a look at how we can use this function, using some illustrative examples!

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.

In this C++ article we are going to talk about Loops Complete Example in C++, we are going to learn different C++ Loops like For Loop, While Loop and Do While Loop. There may be a situation, when you need to execute a block of code several number of times, using loops you can do these kind of functionalities. A loop statement allows us to execute a statement or group of statements multiple times. There are different types of loops that you can use in c++, for loop, while loop, do while loop, also there are different control statements like break and continue in c++ loops, using control statements we can change the execution of loops from its normal sequence.
