Tokens in c programming language

💫 Tokens in C Programming Language👈😍

Tokens are the smallest individual units of a C program.

1. Keywords

Reserved words used by the C language.

Examples:

int, float, char, double, if, else, for, while, do, switch, case, break, continue, return, void, static, struct, union

2. Identifiers

Names given to variables, functions, arrays, etc.

Examples:

  • sum,
  •  total,
  •  main,
  •  average, 
  • result

3. Constants

Fixed values that do not change during program execution.

Types and examples:

  • Integer constants: 10, -5
  • Floating constants: 3.14, 2.5
  • Character constants: 'A', '5'
  • String constants: "Hello"

4. Operators

Symbols used to perform operations.

Examples:

  • Arithmetic: + - * / %
  • Relational: > < >= <= == !=
  • Logical: && || !
  • Assignment: = += -= *=
  • Increment/Decrement: ++ --

5. Special Symbols (Separators)

Symbols used to separate or group program elements.

Examples:

  • () 
  •  {} 
  •  []
  •  ;
  •  ,

History of c programming language

 💫 History of C Programming Language👇 1. Origin of C Language The C programming language was developed in 1972. It was created by Dennis Ritchie. The development took place at Bell Laboratories (AT&T), USA. C was mainly developed to write the UNIX operating system. 2. Influence of Earlier Languages C language was not created suddenly; it evolved from earlier languages: ALGOL (1960) Provided structured programming concepts. BCPL (Basic Combined Programming Language) Developed by Martin Richards. Used for system programming. B Language Developed by Ken Thompson. Used in early UNIX development. C was created by improving B language, adding data types and powerful features. 3. Purpose of Developing C To overcome the limitations of B language. To develop a language suitable for: System programming Operating system development To create a language that is: Fast Portable Close to hardware 4. Development of UNIX Using C Initially, UNIX was written in assembly language. Assembly langu...

Evolution of programming languages

 💥 Evolution of Programming Languages👇😊 (From Basic to Advanced) 1. Machine Language (1st Generation Language – 1GL) Oldest form of programming language Written in binary (0s and 1s) Directly understood by the computer hardware Very fast execution Very difficult to write, read, and debug Machine dependent Example: 10101100 00101010 Limitations: Error-prone No portability Requires deep hardware knowledge 2. Assembly Language (2nd Generation Language – 2GL) Uses mnemonics instead of binary Easier than machine language Needs an assembler to convert to machine code Still machine dependent Example: Copy code Asm MOV A, B ADD A, 1 Advantages: Easier to understand Better control over hardware Disadvantages: Complex for large programs Not portable 3. High-Level Languages (3rd Generation Language – 3GL) Close to human language (English-like) Machine independent Requires compiler or interpreter Easy to learn, write, and maintain Examples: BASIC C C++ Java Python Features: Structured progr...
