The C programming language is a computer programming language that was developed to do system programming for the operating system UNIX and is an imperative programming language. The language itself has very few keywords, and most things are done using libraries, which are collections of code for them to be reused.
In computer programming, control flow or flow of control is the order function calls, instructions, and statements are executed or evaluated when a program is running.
Functions are nothing but the group of statements, which needs to be executed again and again for some repeated tasks.
Array is nothing, but collection of data items of similar kind of values, accessed using a common name.
A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before using it to store any variable address.
In C programming, a string is a sequence of characters terminated with a null character \0 . ... char c = "c string"; When the compiler encounters a sequence of characters enclosed in the double quotation marks, it appends a null character \0 at the end by default.
Structure & Union
Structure and union both are user defined data types which contains variables of different data types.
Files in C
A file is a space in a memory where data is stored. 'C' programming provides various functions to deal with a file. A mechanism of manipulating with the files is called as file management.
Here, we will be seeing some additional topics, which are going to make our coding part easier.
