Class

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.

Question

Consider the following C++ code:
int n
= 1; // global
print1 (int x) {
cout << x + n;
}
plus_n () {
n = n + 2;
print1 (n);
}
main () {
int n;
n = 20;
print1 (5);
n = 40;
plus_n ();
cout << n;
What is the output of the program under?
c. Dynamic scoping rules

Illustrate your knowledge of C-Programming by implementing a ‘Game of Dice’.User will start with 3 lives and 100 initial points. Program will ask the user to roll three dices. If sum of three dices is more than or equal to 15, user will get 10 points. If sum is in the range 10 to 14, user will get 5 points. If sum is less than 10, user will get -10 points. If sum is 3, user will lose one life. For every increase of 50 points, user will get one new life and for every decrease of 50 points, user will lose one life. If at any point, user has 200 or more points, program will display message, ‘Congratulations, You Win!!!’ and end. If user has zero lives or zero points, program will display the message ‘Game Over. Sorry, You Lose.’ and end.Program will use the following user defined functions to implement the game Function ‘DisplayGameRules()’ will display the following message on screen.############################################## ROLL the DICE GAME…

Write a program in C++ that computes the equivalent resistance of a purely series and purely parallel electric circuit. The program will ask the user to choose whether to compute for the equivalent resistance of a series or parallel combination. The user will input three resistance values R1, R2, and R3 in ohms. The program will provide an output of equivalent resistance in series (RS) or parallel (RP). All lines of codes should have a comment. You can only input a number not letters/character should display this is not a number if you input letters Series Rs = R1 + R2+R3 Parallel 1/Rp = 1/R1 + 1/R2 + 1/ R3
