C's Character Set C does not use, nor requires the use of, every character found on a modern computer keyboard. The use of most of this set of characters will be discussed throughout the course. The only characters required by the C Programming Language are as follows: character:- It denotes any alphabet, digit or special symbol used to represent information. Use:- These characters can be combined to form variables. C uses variables, operators, keywords and expressions as building blocks to form a basic C program. Character set :- The character set is the fundamental raw material of any language and they are used to represent information. Like natural languages, computer language will also have well defined character set, which is useful to build the programs. The characters in C are grouped into the following two categories: 1. Source character set a. Alphabets b. Digits c. Special Characters d. White Spaces 2. Execution character set a. Escape Sequence 1. Source character set ALPHABETS Uppercase letters A-Z Lowercase letters a-z DIGITS 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 SPECIAL CHARACTERS WHITESPACE CHARACTERS

Examples are backspacing or moving to a newline .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
