File I/O (Input/Output) in C Language refers to the ability to read from and write to files using C language. The standard I/O library in C provides a set of functions for file I/O operations. The following are some of the commonly used functions for file I/O in C: fopen() This function is used to …
Formatting Input/Output in C language refers to the ability to specify the format in which the data is read or written to the input/output devices. The standard I/O library in C provides a set of functions for formatting input/output operations. The following are some of the commonly used functions for formatting input/output in C: scanf() …
String Input/Output (I/O) in C language is used to read and write strings of characters to and from the input/output devices. The standard I/O library in C provides functions for performing string I/O operations. The following are some of the commonly used functions for string I/O in C: fgets() This function is used to read …
Character Input/Output (I/O) in C language is used to read and write single character data to and from the input/output devices. The standard I/O library in C provides functions for performing character I/O operations. The following are some of the commonly used functions for character I/O in C: getchar() This function is used to read …
In the C programming language, macros and pre-processor directives are powerful tools that allow you to perform certain actions before your code is compiled. They can be used to define constants, include header files, perform conditional compilation, and more. A macro is a fragment of code that is given a name and is replaced by …
In C language, you can use pointers to structures to access and manipulate the members of a structure dynamically, and to pass structures as arguments to functions. Here’s an example: In this example, we first define a struct called student, which contains three members: a character array for the student’s name, an integer for their …
In C language, you can define an array of structures, which is a collection of structures of the same type. This allows you to store and access multiple instances of the same structured data type in a contiguous block of memory. Here’s an example of how to define an array of structures: In this example, …
In C language, an enum is a user-defined data type that consists of a set of named integer constants. An enum declaration defines a new data type with a fixed set of possible values. Here’s an example of an enum declaration: In this example, we’ve defined a new enum type called Color with three possible …
In C language, typedef is a keyword used to give a new name to an existing data type, allowing you to create an alias for that type. This can be useful for making code more readable and for abstracting away implementation details. The syntax for a typedef declaration is: For example, you can create a …
In C language, a union is a user-defined data type that allows you to store different data types in the same memory location. Like structures, unions allow you to group variables of different types under a single name, but with a key difference: only one member of a union can be used at a time. …
In C language, a structure is a user-defined data type that groups together variables of different data types under a single name. A structure is similar to a record or a class in other programming languages. A structure declaration defines a blueprint for the structure, specifying the name of the structure and the member variables …
