Learn how to check a character value in C

When working in C, we can use the ctype.h standard library set of functions to check the value of a char type variable.

We have access to several useful checks:

• isalnum() checks if a character is alphanumeric
• isalpha() checks if a character is alphabetic
• iscntrl() checks if a character is a control character
• isdigit() checks if a character is a digit
• isgraph() checks if a character is a printable ASCII character (but not a space)
• islower() checks if a character is lowercase
• isprint() checks if a character is a printable ASCII character
• ispunct() checks if a character is a punctuation character (a printable char, not a space, not alphanumeric)
• isspace() checks if a character is a whitespace character (see more later)
• isupper() checks if a character is uppercase
• isxdigit() checks if a character is an hexadecimal digit (0-F)

Should you learn C in 2020/2021?

When working with embedded systems that depend on speed or have a minimal amount of memory, C is a perfect language of choice. This is a short paper about why you should learn C and the benefits of doing so.

To add some credibility to this story, let me introduce myself. My name is Eric and I am a computer science student in Sweden. I have been programming for quite some time now and I feel like it is time to share some of my opinions about C, one of the best programming languages to learn.

Background story

C is an old language, to be formal, it appeared the first time in 1972. The language was developed to combines the capabilities of an assembly language with the feature of high-level language.

Despite its age, the language is still widely used today because of its power and ease of use.

When working with embedded systems that depend on speed or have a minimal amount of memory, C is a perfect language of choice.

Because of its age, many individuals claim that C is not necessary, that newer languages could replace it. However, every language has its purpose and that is what I would like to explain to you.

Learn how to print the percentage character using `printf()` in C

When writing a C program you might have the need to print the % percentage character using printf().

Perhaps you are working on a program that calculates percentages, which is kind of common when you’re just learning the language and you’re creating small programs.

How do you do so?

Object Oriented Programming in C++ | C++ OOPs Concepts | Learn Object Oriented 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.

The goal of this course is to provide you with a working knowledge of C++. We’ll start with the basics, including syntax, operators, loops, and functions. This Course will explain you how to use data structures and create your own Functions. This Course will show you the details of the powerful object and template systems so you can create useful classes and objects.

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. 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++.
