Isspace() Function in C
Before moving towards the implementation of C codes, we have to make our system up to date. For this, we have been opening Ubuntu’s every green console application named “Terminal” using a shortcut way, i.e., Ctrl+Alt+T. After the purple query area of the terminal was launched, we tried to execute the “update” instruction using the “apt” utility of our Linux system with “sudo” rights.

Scope in C++
An entity in C++ has a name, which can be declared and/or defined. A declaration is a definition, but a definition is not necessarily a declaration. A definition allocates memory for the named entity, but a declaration may or may not allocate memory for the named entity. A declarative region is the largest part of a program in which the name of an entity (variable) is valid. That region is called a scope or a potential scope. This article explains scoping in C++. Furthermore, basic knowledge of C++ is required to understand this article.

POSIX Socket in C
Within Socket programming, we must have two nodes, i.e., client and a server. An endpoint for transmission is known as a POSIX Socket or just a Socket. For sender and receiver, A and B, to interact with one another, both these sides must first create a link across their particular endpoints. Another socket (endpoint) seeks out the first socket to generate a link, whereas the first socket responds on a certain port upon an IP address. Whereas the client approaches the server, the server generates the listener socket. In this guide, we will be explaining the use of the Socket function from the POSIX library of C while using the Ubuntu 20.04 Linux operating system.

sprintf Function in C
In this article, we will discuss the working of the sprintf() function in the C programming language. The sprintf() function is similar to the printf() function, but the main difference is printf() function is used to display the string exactly that was written in the double quotation marks. The sprintf() function is also used to display the string of characters but it converts the formatted output to the character string buffer.

For Loop in C
When we write a program for different software or hardware applications, there are some commands or tasks that we need to repeatedly execute until we need them or till that statement is false. Have you ever thought about how programmers program their code to do a specific task multiple times? Do they write the specific code for that specific program several times to get it iterated till it is required? If we do this manually, it would be easy if we had to iterate it a few times, say 2 or maybe 3, but if we needed hundreds of iterations, it could become a hurdle for us to write the same program a hundred times. This is where for loops come to the rescue. These loops allow for iteration of the specific program several times with every increment in their condition statements until it is required.
