Command-line arguments in c Command-line arguments in C language give you access to pass arguments/parameters when executing the program from command line/command prompt. These program arguments/parameters provide program input data or options, making it more flexible and customizable for various programming purposes. Accessing command-line arguments in C. man function in C - It can accept…
Bitwise operators in c Bitwise operators in C language manipulate individual bits within an integer type in a storage location. Bitwise operators are commonly used in low-level computer programming, such as low-level computer programming, systems programming, embedded systems, computer hardware, and other applications. Types of Bitwise Operators in C Language. AND (&) OR (|) XOR…
Typedef in c typedef is a reserved keyword in C programming. The typedef keyword is used to create data type aliases for existing data types or to create new named data types. It can simplify program declaration of complex data types, make program code more readable, and make program data types abstract. Basic use of…
Enumerations in c In C programming, enumeration data type (enums) is a user defined data types variable combination element collection like structure. Enumerations contain special constant elements. Enumerations in C program provide different data types values according to user provided values. This makes the enumeration based data type source code more readable and maintainable. Defining…
File inclusion in c File inclusion in C programming means adding the source content of one file to another file. This is usually done using the #include preprocessor directive. Here file inclusion is mainly used to manage large program projects, in which the same program source code is divided into several files. This makes it…
Conditional compilation in c Conditional compilation in C allows you to add or remove features from macros or parts of program code based on certain conditions. This macros program is especially useful for computer platform-specific code, program debugging, and customizing code. Here are some preprocessor directives used for conditional compilation. These are some popular conditional…
Macros in c Macros are a programming art in C programming through the built-in preprocessor. Generally macros are used to define constant data types, program functions and code snippet elements in detail in C language, any macros code is defined and interpreted by the preprocessor in C language. If you want to use macros in…
Error handling In C Programming File Handling Error Management, particular file errors occurring during file operation in a C program are managed and controlled. Error management detects errors occurring during file operation. Many times, while opening a file, we can manage the errors of failures in file open, read, write, append operations. So let's understand…
Sequential and random file access In file handling operation in C programming, any file access can be divided into two types. Which includes sequential file access and random file access methods. So, let's know both sequential access and random file access methods in file handling in detail in the file program example below. Sequential Access…
File operations (opening, closing, reading, writing) File handling in C programming is used for various file operation tasks in C program. By file operation, you can perform file operation tasks like open, close, read, write, etc. in C program. Where you access the file operation function from standard input/output library I/O (stdio.h) header file in…
Union in c Union is a user defined data type member in C programming. Which specifically stores different data types program variables elements in the same memory storage location. In union C structure where each structure member has its own individual memory storage location. All variable members of the same union data type use the…
Structure pointers Using pointer operators for structure data type members allows you to efficiently manipulate structure data type members within the declared structure and to access structure members from memory address locations, especially when dynamic memory allocation is needed for a structure or passing a function to a structure. So let's use structure to pointer…
