4. Write a program in C++ that prints the factorial of the given number using : (a) for loop (b) while loop (c) do-while loop Make sure that the program correctly handles the exceptions such as the value of factorial zero and the value of factorial of a negative number.

5. Write a C++ program that checks whether a number entered by the user is a perfect number or not. (Note: A perfect number is the one whose all the divisors sum up the number itself. For example, number 28 is a perfect number as 1+2+4+7+14=28).

6. Write a program in C++ to read a set of 10 positive integers and display them all. If the number entered is zero, the program continues reading, but when the user input is a negative number, the program stops reading any further input and displays a message: “a negative number entered”.

    | |A program is usually not limited to a linear sequence of instructions. During its process it may bifurcate, repeat code or take decisions. For that purpose, C++ provides control structures that serve to specify what has to be done by our program, when and under which circumstances. With the introduction of control structures we are going to have to introduce a new concept: the compound-statement or block. A block is a group of statements which are separated by semicolons (;) like all C++ statements…
