Basic Syntax Rules
- Case Sensitivity – C++ is case-sensitive, meaning Variable and variable are different identifiers.
- Semicolons (;) – Statements must end with a semicolon.
- Curly Braces ({}) – Used to define blocks of code, like functions or loops.
- Header Files (#include) – Used to include standard or user-defined libraries at the beginning of a program.
- Main Function (main()) – Every C++ program must have a main() function, which serves as the entry point.
In C++, std::string name; declares a variable named name of type std::string. This means name can store a sequence of characters, effectively functioning as a string.
In C++, a struct (short for structure) is a user-defined data type that groups together multiple variables of different types under a single name. It's similar to a class, but by default, its members are public instead of private.
