Q5. Datatype in C++,range and size, Real life example of of Embedded system.
Ans. 
In C++, datatypes have specific ranges and sizes. Embedded systems are real-life examples of using datatypes effectively.
• Datatypes in C++ have specific ranges and sizes to store different types of data efficiently.

• For example, 'int' datatype in C++ typically has a range of -2,147,483,648 to 2,147,483,647.

• Embedded systems use datatypes like 'uint8_t' to efficiently store data in limited memory space.

• Real-life example of...read more

Q7. Write program for number is prime or not prime
Ans. 
Program to determine if a number is prime or not prime
• Create a function to check if a number is prime or not

• Iterate from 2 to the square root of the number and check for divisibility

• If the number is divisible by any number other than 1 and itself, it is not prime

• Return true if the number is prime, false otherwise

Q8. Write code for fibonacci series
Ans. 
Code to generate Fibonacci series using iterative approach
• Initialize an array to store the Fibonacci series

• Start with the first two numbers in the series (0 and 1)

Q9. What is constructor, destructor, polymorphism, Static function, volatile keyword
Ans. 
Constructor initializes an object, destructor cleans up resources. Polymorphism allows objects to be treated as instances of their parent class. Static function belongs to the class, not instances. Volatile keyword indicates a variable may be changed unexpectedly.
• Constructor initializes an object when it is created. Example: 'Car c = new Car();'

• Destructor cleans up resources when an object is destroyed. Example: 'delet...read more
