Closures originated from the world of functional programming, but as programming languages have evolved recently they have been liberally borrowing ideas from other languages and paradigms. In this post, we will look at closures through the lens of C#.
Closures are like those optical illusions that seem normal when you first look at them, however, their magic unfolds on closer inspection.

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.

Developing a mobile application can often be more challenging than it seems at first glance. Whether you’re a developer, UI designer, project lead or CEO of a mobile-based startup, writing good project briefs prior to development is pivotal. According to Tech Jury, 87% of smartphone users spend time exclusively on mobile apps, with 18-24-year-olds spending 66% of total digital time on mobile apps. Of that, 89% of the time is spent on just 18 apps depending on individual users’ preferences, making proper app planning crucial for success.
Today’s audiences know what they want and don’t want in their mobile apps, encouraging teams to carefully write their project plans before they approach development. But how do you properly write a mobile app development brief without sacrificing your vision and staying within the initial budget? Why should you do so in the first place? Let’s discuss that and more in greater detail.
It’s worth discussing the significance of mobile app project briefs before we tackle the writing process itself. In practice, a project brief is used as a reference tool for developers to remain focused on the client’s deliverables. Approaching the development process without written and approved documentation can lead to drastic, last-minute changes, misunderstanding, as well as a loss of resources and brand reputation.
For example, developing a mobile app that filters restaurants based on food type, such as Happy Cow, means that developers should stay focused on it. Knowing that such and such features, UI elements, and API are necessary will help team members collaborate better in order to meet certain expectations. Whether you develop an app under your brand’s banner or outsource coding and design services to would-be clients, briefs can provide you with several benefits:
Depending on how “open” your project is to the public, you will want to write a detailed section about who the developers are. Elements such as company name, address, project lead, project title, as well as contact information, should be included in this introductory segment. Regardless of whether you build an in-house app or outsource developers to a client, this section is used for easy document storage and access.

Nine times out of ten, you will come across a job ad that lists C/C++ as a skill requirement.
No matter the company, the job title, or the salary, you will likely find that the job description lists C/C++ as a required skill. Better yet, they want you to have 10+ years of experience using these technologies.
Why are these two languages from the 70s and 80s required for modern-day software developer positions?
Some will joke and say it’s because the employers are looking for candidates over the age of 50. Others will say it’s because the HR hiring managers have a lukewarm IQ that led them to copy and paste whatever Google listed as popular programming languages.
The bottom line is that anyone at any level in their software development career will come across this requirement for any job under the sun, be it as a software engineer, web developer, game programmer, or app developer. With so many different companies looking for this skill for any number of positions, it begs the question: what are recruiters actually looking for when they list C/C++ in a job description?
At this point, it’s pure speculation as to what recruiters really want. However, a few good explanations can help future software developers wisely navigate the omnipresent C/C++ requirement.
Having an understanding of C and C++ allows you to fill any number of roles within a company.
Employers will often include C/C++ as a skill requirement as part of a broad job description to find candidates who could fulfill any number of positions or job requirements under the software developer umbrella. Often, employers are looking for someone who can do any of the following:
All of the tasks above can be done using more modern programming languages, yet are often taken over or completed using C or C++. C and C++, while ancient languages in terms of the speed at which technology modernizes, are still relevant for many different tasks that you may come across as a developer.

Inside a function, you can initialize a static variable using the static keyword.
I said “inside a function”, because global variables are static by default, so there’s no need to add the keyword.
What’s a static variable? A static variable is initialized to 0 if no initial value is specified, and it retains the value across function calls.
