Make sure a password has been set on the computer and make sure its one that you know is easy to memorize but hard for others to find out. firewall - software firewall is a program that is stored into the computer which protects the computer from unauthorized incoming and outgoing data. virus protection program - that helps stop or detect and fix virus problems from happening.
Define 'low level memory' first.
Yes, C++ has pointers, which are references to memory locations. which are variables that store memory addresses, or NULL (zero). If the pointer is non-NULL, the pointer is said to dereference the object (or variable) residing at the stored memory address, which permits indirect access to that object so long as the object remains in scope.
A pointer is a variable that stores the memory address of another variable, allowing for direct manipulation of memory. It enables efficient access and modification of data structures, such as arrays and linked lists, by referencing their locations in memory rather than their values. Pointers are commonly used in programming languages like C and C++ for dynamic memory management and to enhance performance.
Java does not have the concept of Reference Variables. We cannot access the memory location where the data is stored in Java.
Main Memory (RAM).

The address operator in C is denoted by the symbol "" and is used to retrieve the memory address of a variable. This allows programmers to access and manipulate the memory location of a variable directly, enabling more efficient and precise control over memory management in their programs.

Memory corruption in C refers to situations where a program unintentionally alters the contents of memory locations that it is not supposed to access or modify. This can lead to unexpected and potentially dangerous behavior, such as crashes, data corruption, or security vulnerabilities. Memory corruption in C is often a result of issues like buffer overflows, uninitialized variables, or improperly managed memory allocations.
C language is a middle level language, a middle language is one which somehow allows you to access your computer memory directly. Where as Java and C# are completely highlevel language as they dont allow you to directly access your computer memory, Assembly Language is said to be the low level language as it allow the the direct access of memory. you can read more on C language here: http://thetechnofreaks.com/2011/08/23/the-basics-welcome-to-the-world-of-programming/ Actually, there are no 'middle level languages', machine code and Assembly is low level, everything else is high level. And of course you cannot break out from your virtual memory space using C (or any other language). It is called 'protected mode' for a reason.

# Manual memory allocation/deallocation # (Semi-) direct access to registers
There is no memory management operator in C++ -- it is an unmanaged language. You use the C++ new operator to allocate memory, and use the C++ delete operator to release previously allocated memory.
