Rust Programming Master Class from Beginner to Expert - Application Memory (Heap and Stack)

This tutorial explains why ownership is transferred in non-primitive types like strings and vectors in Rust. It covers memory management, including stack and heap memory, and how Rust handles memory safety through ownership. The tutorial provides a detailed look at memory segments, stack frames, and the heap's role in storing data with unknown sizes. It concludes with an understanding of Rust's approach to memory safety and ownership.

Why is ownership transferred for non-primitive types like strings in Rust?

• Because they are stored in the heap.

• Because they are global variables.

• Because they are stored in the stack.

• Because they are immutable.

Which memory segment stores the program instructions and code?

• Text segment

• Stack

• Global variables segment

• Heap

What is a stack frame?

• A section of memory for function calls and local variables.

• A section of memory for storing vectors.

• A section of memory for global variables.

• A section of memory for storing strings.

What happens when the stack grows beyond its reserved memory?

• Stack overflow

• Heap overflow

• Garbage collection

• Memory leak

Where must data with an unknown size at compile time be stored?

• Heap

• Global segment

• Text segment

• Stack

What is a common cause of stack overflow?

• Using too many string variables

• Allocating too much heap memory

• Using too many global variables

• Declaring variables in a loop

How does Rust ensure memory safety with heap allocations?

• By using global variables.

• By using ownership and borrowing.

• By using manual memory management.

• By using garbage collection.

What happens to a variable in Rust when it goes out of scope?

• It is moved to the heap.

• It is deallocated automatically.

• It is moved to the stack.

• It remains in memory until the program ends.

What is the role of the operating system in heap allocation?

• No involvement

• Significant involvement

• Minimal involvement

• Only during program start

What does Rust do to avoid memory leaks?

• Uses garbage collection

• Automatically deallocates memory

• Relies on manual memory management

• Uses global variables
