The following question is related to C programming (struct and function) Task-1: Suppose you and your friends go to have breakfast in a restaurant. Each of you orders Paratha, Vegetable, and Mineral Water. Treat each of the ordered items as structures and each of the structures will have two properties which are: quantity and unit price. Each property of the structure will be taken as input from the user. After taking all the inputs calculate what is the total bill and also, take input from the user on how many people are there in total. Lastly calculate how much each person will have to pay and print it (Note: This value will be a float). Sample Input: Quantity Of Paratha: 25 Unit Price: 10 Quantity Of Vegetables: 5 Unit Price: 20 Quantity Of Mineral Water: 20 Unit Price: 20 Number of People: 6 Sample Output: Individual people will pay: 125.00 tk
Write a C++ program that will use good object-oriented principles.You have been tasked to write an application that will allow a user to change their system password. The XYZ Corporation has the following rules for passwords: each password should have a minimum of 8 characters each password should have a minimum of 2 uppercase characters (A - Z) each password should have a minimum of 2 lowercase characters (a - z) each password should have a minimum of 2 digits (0 - 9) each password should have a minimum of 2 special characters of which the following characters are allowed: !, @, $, %, and & (in any combination) Once the user has created a new password that passes the above requirements, the user must then retype the password for the program to verify that the same password was entered by the user. If the user creates a password that does not meet the minimum requirements, be sure to let the user know the entered password does not meet the minimum requirements and allow the…
Consider the following program in C-like syntax:void f1();void f2();int main(){int x, y;...}int f1()int a, b, x;...}int f2(){int b, c, x, y;...} If the programming language uses dynamic scoping, what are the variables that arevisible in the last function in the following call sequences? Give not only the names ofthe variables, but also where they are declared.(a) main → f1 → f2(b) main → f2 → f1
Define a C++ language float literal using regular expression. A float literal in C language has an optional exponent part. If a float literal is written without exponent part, then it must have a decimal point which can appear at the start, at the end or in the middle of digits, as in following examples: 123.456 .456 456. If float literal is written with exponent, then decimal point in mantissa part is optional, and exponent is a whole number with optional sign, as in following examples: 123e78 123e+78 123e-78 123.456e78 .456e78 456.e78

Siyazama High School Grade Management The Siyazama High School principal approached you for your C++ Programming expertise. They want a software solution for their teachers who manage student marks. The teachers record the student’s name and surname, the continuous assessment mark out of a 100 and the final term mark out of a 100. They then always search for information such as the best or worst performer per mark (continuous or term) and sometimes they search for a particular student’s marks. Write a C++ program that will allow the teachers to do the following: Capture the student performance record in a sentinel-controlled loop and store the results in three parallel arrays. The information to be stored in the three arrays is the student’s full name, continuous assessment mark, and final mark. If the lecturer types the word ‘Done’ instead of a full name, the loop should immediately stop even before capturing any marks. Search the array for the student’s full name and then…

Define a struct fruitType to store the following data about a fruit: Fruit name (string), color (string), fat (int), sugar (int), and carbohydrate (int). Declare a variable of type fruitType to store the following data: Fruit name—banana, color—yellow, fat—1, sugar—15, carbohydrate—22. Write a C++ function, getFruitInput to get and store data into a variable of fruitType. Write a C++ function, printFruitInfo to output data stored into a variable of fruitType. Use appropriate labels to identify each component. Test your solution by calling all funtions.

A parameter in a C++ function is passed by reference. Which of following statement is true?I. The reference of the real parameter is passed to the formal parameter; II. Changing the value of the formal parameter in the function will not change the real parameter; III. Changing the value of the formal parameter in the function will change the real parameter as well.

Write a program in c++: Consider that a system has two entities, Employee and Department. The employee has the following properties: employee name, number, SSN and salary. Similarly, the department has the following properties: department name, department number and a set of employees who are working on that department. Implement the above system taking into account the following requirements: In department, the number of employees that are working on this department is decided at the time when instantiating the department. Assume that emp1 and emp2 are two objects of type Employee, write a code that enables you to write: if (emp1.isequal (emp2)). Where emp1, emp2 are employee objects. The statement is true if the objects have the same salary. In department, make sure no two employees have the same employee number. In department, write a method to increase the salary of an employee by a specific value.it should validate that value. Write a getEmpByEno method in class department that…
