Programming Fundamentals

Function overloading in programming allows multiple functions with the same name to operate on different data types by using distinct parameter signatures.

The ternary operator (?:) is a built-in operator in C++ and cannot be overloaded.

In C++, if a function definition appears in the source file before any calls to that function, a separate function prototype declaration is not strictly required.

To access a member of a structure using a pointer, the arrow operator (->) is used. However, if you have a direct structure variable, you use the dot operator (.) to access its members.

Destructors are called automatically when an object goes out of scope and they do not accept any parameters, nor do they return any value.

Constructors are special functions that initialize objects and are defined without any return type, not even void.

Relocation bits, which indicate which parts of an object code need address adjustment during loading, are generated and provided by the assembler or translator when converting source code to machine code.

If the test condition fails, the do-while loop will enter the loop body once.

Instance variables are given default if not initialised

The 'FOR-DO' construct (or a standard 'do-while' loop in many languages) is designed to execute the loop body at least once before checking the condition.

A WHILE-DO loop checks the condition before executing the loop body. If the condition is false initially, the loop body executes zero times.

Macros are expanded during program execution. A macro is a group of instructions that perform tasks.

In the OSI model, each layer is designed to perform a specific, well-defined function.
