Design patterns in C++ are reusable solutions to common problems in software design.

• Design patterns help in creating flexible, maintainable, and scalable code.

• Examples of design patterns in C++ include Singleton, Factory, Observer, and Strategy.

• Each design pattern has its own purpose and can be applied in different scenarios.

• Understanding design patterns can improve code quality and efficiency.

Structure is a collection of variables of different data types while union is a collection of variables of same data type.

• Structure allocates memory for all its variables while union allocates memory for only one variable at a time.

• Structure is used when we want to store different types of data while union is used when we want to store only one type of data.

• Structure is accessed using dot operator while union is access...read more

Dangling pointers can be avoided by setting them to NULL after freeing the memory they point to.

• Always initialize pointers to NULL.

• Set pointers to NULL after freeing the memory they point to.

• Avoid accessing memory through a pointer after it has been freed.

• Use smart pointers or garbage collection to automate memory management.

A program to print Fibonacci series using recursion.

• Define a recursive function that takes an integer n as input

• Base case: if n is 0 or 1, return n

• Recursive case: return the sum of the previous two Fibonacci numbers

• Call the recursive function with the desired number of terms and print the result

Embedded C is a subset of the C programming language, specifically designed for programming embedded systems.

• Embedded C is optimized for resource-constrained systems with limited memory and processing power.

• It includes additional keywords and features for controlling hardware directly.

• Embedded C often involves working with microcontrollers, sensors, and other hardware components.

• Regular C can be used for general-purpos
