- Concept of OOPs. C is a very vast language, but it does not support the concept of OOPs (Inheritance, Polymorphism, Encapsulation, Abstraction, Data Hiding).
- Run-time checking.
- Concept of namespace.
- Lack of Exception Handling.
- Constructor or destructor.
- Low level of abstraction.
What is unique about C?
C is completely flexible when it comes to reading and writing arbitrary memory locations. This flexibility comes at a great cost, and has been the cause of many bugs across the software spectrum. Most notable and affecting the entire internet include such bugs in web servers, mail servers and ftp servers.
What is c and its features?
It was mainly developed as a system programming language to write an operating system. The main features of C language include low-level access to memory, a simple set of keywords, and a clean style, these features make C language suitable for system programmings like an operating system or compiler development.
What are keywords in C?
Keywords are predefined, reserved words in C language and each of which is associated with specific features. These words help us to use the functionality of C language. They have special meaning to the compilers. There are total 32 keywords in C.
What is the importance of keywords in C?
Keywords are the words whose meaning has already been explained to the C compiler and their meanings cannot be changed. Keywords serve as basic building blocks for program statements. Keywords can be used only for their intended purpose. Keywords cannot be used as user-defined variables.
What are the 32 keywords in C language?
A list of 32 Keywords in C++ Language which are also available in C language are given below.
| auto | break | const |
|---|---|---|
| double | else | float |
| int | long | short |
| struct | switch | unsigned |
What are functions C?
A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions. A function declaration tells the compiler about a function’s name, return type, and parameters.
What is the main function of C language?
main() function is the entry point of any C program. It is the point at which execution of program is started. When a C program is executed, the execution control goes directly to the main() function. Every C program have a main() function.
What are the categories of functions in C?
What are the different categories of functions in C Programming?

- Functions without arguments and with return values.
- Functions with arguments and without return values.
- Functions with arguments and with return values.
What are the 4 types of functions in C?
There can be 4 different types of user-defined functions, they are:
- Function with no arguments and no return value.
- Function with no arguments and a return value.
- Function with arguments and no return value.
- Function with arguments and a return value.
What are the two categories of function in C?
There are two types of function in C programming:
- Standard library functions.
- User-defined functions.
What are functions and its types in C language?
There are two types of functions in C programming: Library Functions: are the functions which are declared in the C header files such as scanf(), printf(), gets(), puts(), ceil(), floor() etc. User-defined functions: are the functions which are created by the C programmer, so that he/she can use it many times.
What are data types in C?
Data Types in C
| Types | Data Types |
|---|---|
| Basic Data Type | int, char, float, double |
| Derived Data Type | array, pointer, structure, union |
| Enumeration Data Type | enum |
| Void Data Type | void |
What is array in C?
An array is a collection of data items, all of the same type, accessed using a common name. A one-dimensional array is like a list; A two dimensional array is like a table; The C language places no limits on the number of dimensions in an array, though specific implementations may.
What is structure in C language?
Structure is a user-defined datatype in C language which allows us to combine data of different types together. Structure helps to construct a complex data type which is more meaningful. It is somewhat similar to an Array, but an array holds data of similar type only. In structure, data is stored in form of records.
What are the 2 main types of data structures?
There are two fundamental kinds of data structures: array of contiguous memory locations and linked structures.
What is C structure size?
A) C structure is always 128 bytes.
