/*Hello friends I am giving you the most important key points that you should never forget as a C++ programmer*/
Important points based on data types,variables & Expressions:-
- Every programming language has two fundamental elements, viz., data types and variables.
- In C++, the data types are classified as three main categories (1) Built-in data types (2) User-defined data types (3) Derived data types.
- The variables are the named space to hold values of certain data type.
- There are five fundamental data types in C++: char, int, float, double and void.
- C++ compiler allocates specific memory space for each and every data handled according to the compiler’s standards. Variables are user-defined rames assigned to a memory location in which the values are stored.
- Declaration is a process to instruct the compiler to allocate memory as per the type specified along with the variable name.
- Manipulators are used to format output of any Ct+ program. Manipulators are functions specifically designed to use with the insertion (<<) and extraction(>>) operators.
- An expression is a combination of operators, constants and variables arranged as per the rules of C++.
- The process of converting fundamental data type into another is called as “Type Conversion? C++ provides two types of conversions (1) Implicit type conversion and (2) Explicit type conversion.
