Prerequisite – C Language Introduction C comments explain code and improve readability. These do not affect program execution. You can use comments in C to clarify code and describe algorithms. There are two types of comments in C: single-line (//) commnets and multi-line (/* */) comments. 1. Single-line comments start with “//” and end at the end of the… Read More »
Prerequisite – C Language Introduction The C programming language has various versions: C89/C90, C99, C11, and C18. C89/C90: Released in 1989/1990. It introduced key language features. C99: This brought new features like variable-length arrays and complex numbers. C11: This added _Generic, static_assert, and library updates. C18: It is latest standard, with clarifications and updates. Advantages: 1. Efficiency: C… Read More »
C is a programming language developed by Dennis Ritchie in 1972. It has a significant historical impact. It was originally created at Bell Laboratories of AT&T Labs for building the UNIX operating system. Key Features of C C is a versatile and general-purpose programming language. It is portable across different systems and platforms. So it suitable for various… Read More »
The string.h header defines one variable type, one macro, and various functions for manipulating arrays of characters. Functions provided by string.h The string.h header file declares a set of functions to work strings. To perform operations like comparison, concatenation, and copying, this string.h library is widely used. This header file defines several functions to manipulate C strings and… Read More »
math.h is a header file in the C Standard Library, which is commonly used in C programming. It is designed for basic mathematical operations. This header file defines a set of functions and macros that provide mathematical functions capabilities for C programs. Some of the most commonly used functions in math.h are sqrt, log, sin, cos, tan, exp,… Read More »
In C programming language, a string is a sequence of characters that are stored in an array of characters. The string is terminated with a null character (‘\0’) which marks the end of the string. In C, strings are stored as arrays of characters, and each character in the array represents a character in the string. For example,… Read More »
In the C programming language, a literal is a value that appears directly in the source code. There are several types of literals in C, including: Integer literals – An integer literal is a whole number without a fractional component, such as 42 or -17. int a = 42; long b = -17; unsigned int c = 123456;… Read More »
C is a high-level programming language that was developed in the 1970s and is still widely used today. It is used to develop a wide range of applications, including system software, games, and desktop and mobile applications. Here are some of the most commonly used C commands: printf: This function is used to display output on the screen.… Read More »
Variables in C In C, a variable is a storage location that has a name and holds a value. A variable must be declared before it is used in a program. The syntax for declaring a variable in C is: where data_type is the type of the data that the variable will store, and variable_name is the name… Read More »
Here are some of the best C compilers: GCC (GNU Compiler Collection): GCC is one of the most popular and widely used compilers for C and other programming languages. It is an open-source compiler and supports multiple platforms including Windows, Linux, and macOS. Clang: Clang is an open-source compiler that is developed by the LLVM project. It is… Read More »
