Program Plan Intro
Exception:
- • An exception is an error that occurs during a
program execution. - • The program execution stops abruptly when an exception occurs in the program.
- • To handle exceptions in the Python programs, the “try/except” statements are used.

PARTICIPATION
ACTIVITY
Arrange the following lines to make a program that determines when the number of people in a restaurant equals or exceeds 10
occupants. The program continually gets the number of people entering or leaving the restaurant. Ex: 2 means two people
entered, and -3 means three people left. After each input, the program outputs the number of people in the restaurant. Once the
number of people in the restaurant equals or exceeds 10, the program exits.
If an Input MismatchException exception occurs, the program should get and discard a single string from input. Ex: The input "2
abc 8" should result in 10 occupants. Not all lines are used in the solution.

- PROGRAMMING LANGUAGE: C++ TASK 1. You are required to create a simulation of an elevator system. There are 7 floors in a building. A user may enter the elevator and press the button of the destined floor. The simulation should display appropriate messages while moving towards the destined floor. Task 2. Write a program that takes +,-,*, and / operators and performs the required operation. the program will continue to execute until ESC key is pressed. Also, the usage of post-test loop and switch statement is mandatory.arrow_forwardC++ Programming: Instructions The program in Example 5-6 implements the Number Guessing Game. However, in that program, the user is given as many tries as needed to guess the correct number. Rewrite the program so that the user has no more than five tries to guess the correct number. Your program should print an appropriate message, such as “You win!” or “You lose!”. Code Given: //Flag-controlled while loop. //Number guessing game. #include <iostream> #include <cstdlib> #include <ctime> using namespace std; int main() { int num; //variable to store the random number int guess; //variable to store the number guessed by the user bool isGuessed; //boolean variable to control the loop srand(time(0)); num = rand() % 100; isGuessed = false; while (!isGuessed) { cout << "Enter an integer greater" <<" than or equal to 0 and " <<"less than 100: "; cin >> guess; cout << endl; if (guess == num) { cout << "You win!
