C Programming
C++ is a powerful general-purpose programming language. It can be used to develop operating systems, browsers, games, and so on. C++ supports different ways of programming like procedural, object-oriented, functional, and so on. This makes C++ powerful as well as flexible
Why Learn C++?
-C++ is used to develop games, desktop apps, operating systems, browsers, and so on because of its performance.
-After learning C++, it will be much easier to learn other programming languages like Java, Python, etc.
-C++ helps you to understand the internal architecture of a computer, how computer stores and retrieves information.
C Programming Data Types
You will learn about basic data types such as int, float, char etc. in C programming. In C programming, data types are declarations for variables. This determines the type and size of data associated with variables
In the C programming language, data types constitute the semantics and characteristics of storage of data elements. They are expressed in the language syntax in form of declarations for memory locations or variables. Data types also determine the types of operations or methods of processing of data elements.
Example
Int MyWebste
MyWebsite is a Variable of int(integer) Type. The Size of int 4byte.
Basic Types
Here's a table containing commonly used types in C programming for quick access.
| Type | Size(byte) | Format Specifiter |
|---|---|---|
| Int | at least 2, usually 4 | %d, %i |
| Char | 1 | %c |
| Float | 4 | %f |
| Double | 8 | %lf |
| Short int | 2 usually | %hd |
| Unsigned int | at least 2, usually 4 | %u |
| Long int | at least 4, usually 8 | %ld, %li |
| Long Long int | at least 8 | %lld, %lli |
| Unsigned Long int | at least 4 | %lu |
| Unsigned Long Long int | at least 8 | %llu |
| Singned char | 1 | %c |
| UnSingned char | 1 | %c |
| Long Double | at least 10, usually 12 or 16 | %Lf |
init
Integers are whole numbers that can have both zero, positive and negative values but no decimal values.
float and double
float and Double are used to hold real numbers.
char
Keyword Char is used for declaring character type variables.
short and long
If you need to use a large number, you can use a type specifier Long
Signed and unsigned
In C, Signed and UnSigned are type modifiers. You can alter the data storage of a data type by using them.
