c++ introduction

C++ is a cross-platform language that can be used to create high-performance applications.

C++ was developed by Bjarne Stroustrup, as an extension to the C language.

C++ was developed as an extension of  C language

C++ is a middle-level, general-purpose programming language designed for system and application programming. 

It was developed by Bjarne Stroustrup at Bell Labs in 1983 as an extension of the C programming language. 

C++ is object-oriented as well as supports procedural-oriented programming styles.

One of the key features of C++ is its ability to support low-level, system-level programming, making it suitable for developing operating systems, device drivers, and other system software. 

At the same time, C++ also provides a rich set of libraries and features for high-level application programming, making it a popular choice for developing desktop applications, video games, and other complex applications.

• basic syntax of C++ program

Primitve Data types in c++

Data Types  Memory Size      Range

• int          4     -2,147,483,648 to 2,147,483,647
• float          4     -3.4×10^38 to 3.4×10^38
• char          1     -128 to 127

there are also other data types also:

boolean: boolean data type has two values true or false

              if you get 0, so it is false 

              if you get 1, so it is true

void :valueless

variables

variables are like containers that are used to store data on a temporary basis.

syntax:

data_type var_name=value;

example:

int age=16;

float height=4.5;

char gender='m';
