Shorts notes c language

 C is a general-purpose programming language developed in 1972 by Dennis Ritchie at  Bell Labs.

C is a compiled language, meaning that the code is converted into machine- readable format before execution.

C is low-level language, meaning that it provides a deal of control over hardware resources and memory allocation.

C is often used for system programming, embedded systems, and other application where performance and control are critical.

C is a procedural language, meaning that it follows a step-by-step approach to solving problems.

C supports a wide range of data types, including integers, floating-point numbers, characters, and arrays.

C provides a rich set of operators for performing mathematical and logical operations.

C includes standard libraries for performing common tasks, such as input/output operations and string manipulation.

C code is typically written in a text editor and complied using a C complier, such as GCC or clang.

C code can be run on a wide range of platforms, including Windows, Linux, and macOS.


C is a powerful general-purpose programming language that is widely used for developing various types of software applications. Here are some short notes on C:


Syntax: C programming language has a simple syntax that is easy to learn and understand.


Variables: In C, variables are used to store data values. Each variable has a specific data type, such as int, float, char, etc.


Data Types: C supports a wide range of data types, including integers, floating-point numbers, characters, and strings.


Operators: C provides various operators such as arithmetic, relational, logical, bitwise, etc. for performing operations on variables.


Control Structures: C provides various control structures such as if-else, switch-case, loops, etc. for controlling the flow of execution of a program.


Functions: In C, functions are used to break the program into smaller modules, making it easier to understand and debug.


Pointers: C provides pointers, which are variables that store memory addresses. Pointers are useful for dynamic memory allocation and accessing array elements.


Arrays: C supports arrays, which are collections of elements of the same data type. Arrays are useful for storing large amounts of data.


Structures: C supports structures, which are user-defined data types that can hold a collection of variables of different data types.


File Handling: C provides file handling functions, which allow programs to read and write data to files on the disk.


Overall, C is a powerful and flexible programming language that is widely used for developing various types of software applications, including system software, application software, and embedded software.
