What are fundamental of C programming?

• The C character set, identifiers and keywords, data types, constants, arrays, declarations, expressions, and statements are the fundamental building blocks used to create a straightforward C programme.
•  The C character set:Basic programme elements are created in C using the letters A to Z in lowercase and capital, the numbers 0 to 9, a few special characters, and white spaces (e.g variables , constants, expressions etc.)
• The following white spaces are employed in C programmes: new line, form feed, carriage return, blank space, and horizontal tab.
• Keywords and Identifiers: Variables, functions, and arrays are all given names in a programme called an identifier. In any order, letters and digits make up an identifier, but the first character must be a letter.
• The underscore, which is regarded as a letter as well, is likewise acceptable in addition to upper- and lowercase letters. Lowercase and uppercase letters are not interchangeable since they are not equal. C is thought to be case sensitive for this reason. An identifier may be any length.
