C++ Syntax Basics

C++ syntax uses semicolons and curly braces with strong typing.

Introduction to C++ Syntax

C++ is a statically typed, compiled programming language that requires a specific syntax to function correctly. The syntax consists of a set of rules and symbols used to structure the code, allowing it to be compiled and executed efficiently. Two critical components of C++ syntax are the use of semicolons to terminate statements and curly braces to define the scope of code blocks.

Using Semicolons in C++

In C++, every statement must end with a semicolon (;). This tells the compiler that the statement is complete. Missing a semicolon where required will result in a compilation error.

Here is an example demonstrating the use of semicolons:

Curly Braces for Code Blocks

Curly braces ({}) are used in C++ to define the beginning and end of code blocks. These blocks can be functions, loops, conditional statements, or any other structure that requires grouping multiple statements.

Here is an example using curly braces to define a function and a loop:

Strong Typing in C++

C++ is a strongly typed language, meaning that every variable must have a declared type, and type conversions must be explicit. This ensures type safety and helps prevent errors.

Here is an example illustrating strong typing:

In the example above, both integerVariable and doubleVariable have explicitly defined types. The addition operation involves an implicit conversion from int to double, which is handled by the compiler.
