What is the primary entry point in a C++ program?

Header files compile.

Global variables load.

A constructor initializes.

The main function executes first.

How does variable scope affect program structure?

Local variables limit accessibility.

Scope prevents code reuse.

Global variables persist forever.

Variables share memory always.

What role does a loop play in basic programs?

Repeats code blocks efficiently.

Declares new variables.

Executes code once only.

Halts program execution.

In what order are functions typically structured?

Prototypes before definitions.

Only in main function.

Definitions before prototypes.

Random order works fine.

Why use include directives in programs?

To import header files.

To declare main function.

To end program execution.

To initialize variables.
