The above video is an extract from the online course – “C Programming: The ultimate guide for beginners” which we are currently working on. Consider subscribing to Youtube channel – Aptuts in order to get latest updates on new videos and online C programming course.

C programming is a language developed by AT & T’s Bell Laboratories of USA in 1972. It was designed and written by a man named Dennis Ritchie. C language is reliable, simple and easy to use. It has survived for more than 4 decades. This language is a base to learn different programming language.

If you want to learn C++ or JAVA, without the knowledge of C, it becomes very difficult to learn these programming languages. Many major components of popular operating systems like Windows, UNIX, LINUX are still written in C.

Nothing beats C language in terms of speed of execution.

Before starting with programming, let’s have a look at the C Character set.

C programming character set

Any alphabet, digit or special symbol can be termed as a character. Below table shows list of valid alphabets, digits and symbols allowed in C.

Alphabets:

A, B, C, D, … ,X, Y, Z
a, b, c, d, … ,x, y, z

Digits :

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Special Symbols :

~ ‘ ! @ # % ^ & * ( ) _ - + = | \ { }
[ ] : ; " ' < > , . ? /

Note: These are the valid character sets according to C standards. Most recent compilers such as GNU C allow usage of “$” as a special symbol. “$” is part of the extension provided by new compilers. However, it is not valid as per C standard.

Following are the basic data types in C programming:

1. Numeric data type: deals with numeric data such as integer or float data type
2. Non-numeric data type: deals with non numeric data such as characters
3. Integer data type: deals with integer or whole number
4. Real data type: deals with numeric data that includes fractions
5. Enumerated data type: These data types are defined by the user

C is awesome to learn. Initially, while starting with C programming, you might find it bit difficult. But, once you get hold of it, you will find C very easy. So the key takeaway is if you want to learn C, don’t loose hopes. If you have any questions related to C then please feel free to post your comments.
