What is main topics in c language?

Answer 1

C, the most popular programming language, is created by Dennis Ritchie. This language is mostly used in embedded systems and applications requiring strong interfaces This is a procedure-oriented programming language being easy, simple, efficient and helpful in debugging. The dynamic memory allocation concept, i.e. malloc, calloc, free and realloc makes C one of the most demanding languages.

Some of the main topics in C include:

Features of C language - efficient, fast, portable, modular, statically typed.

Variables and datatypes - Variables are the named location used to store the value during the execution of the program. Datatypes define the types of variables These are generally of two types - basic data types and derived data types. Basic data types include integer, float and character. Derived data types include arrays, pointers, structures and enums.

Operators - to perform any operations, we use operators. The values on which operations are done are referred to as operands. Some of the important operators include the assignment operator, arithmetic operator, logical operator, bitwise operator, comparison operator, etc.

Expressions and Identifiers - identifiers are the user-defined name given to variables, functions, etc. Expressions are operators and operands combined together.

Conditional Statements - These statements decide which statements are to be executed based on the different conditions given in the code. Basically, there are three conditional statements in C language. They are - if statement, if-else statement and nested if-else statement.

Loops - These statements are used for code reusability. Loops help repeat the same code block until the required condition is met. Three types of loops are present in C. They are: for loop, while loop and do-while loop.

Break and Continue - The break statement is used to terminate the loop, and the continue statement is used to skip the current iteration.

Functions in C - functions are the block of code designed to perform a particular task and can be called each time the task has to be done. There are two types of functions: library function and user-defined function.

Call by Value - Actual value is passed to the function in the Call by value method.

Pointers - a variable containing the address of another variable is referred to as a pointer.

Call by Reference - In Call by reference address of the variable is passed.

Array - Arrays are derived data types used to store multiple variables of the same data type in a single variable. Arrays are followed by square brackets [].

Strings - strings are generally referred to as sequences of characters which are then terminated by a null character. They are stored in double inverted commas. These are of character data type.

Structures - structures contain collections of different data types.

File Handling - it includes the details of how files are created, stored, read, operated and manipulated.

Storage Classes - auto, extern, register and static- are C's four storage classes.
