Textbook Question
Chapter 8, Problem 8.10HW
In this chapter, we have introduced some functions with, unsual call and return behaviors longjmp, execve, and fork. Match each function with one of the following behaviors:
- A. Called once, returns twice
- B. Called once, never returns
- C. Called once, returns-one or more times

Students have asked these similar questions
int p =5 , q =6;
void foo ( int b , int c ) {
b = 2 * c ;
p = p + c ;
c = 1 + p ;
q = q * 2;
print ( b + c );
}
main () {
foo (p , q );
print p , q ;
}
Explain and print the output of the above code when the parameters to the foo function are passed by value. Explain and print the output of the above code when the parameters to the foo function are passed by reference. Explain and print the output of the above code when the parameters to the foo function are passed by value result. Explain and print the output of the above code when the parameters to the foo function are passed by name.

Question P .Write the implementation (.cpp file) of the Acc2 class of the previous exercise. The full specification of the class is: An data member named sum of type integer. A constructor that accepts no parameters. THe constructor initializes the data member sum to 0. A function named getSum that accepts no parameters and returns an integer. getSum returns the value of sum .

- JS In this challenge, you must verify the equality of two different values given the parameters a and b. Both the value and type of the parameters need to be equal. The possible types of the given parameters are: What have you learned so far that will permit you to do two different checks (value and type) with a single statement? Implement a function that returns true if the parameters are equal, and false if they are not. Examples checkEquality(1, true) → false // A number and a boolean: the value and type are different. checkEquality(0, "0") → false // A number and a string: the type is different.arrow_forwardThe following program contains a simple class that is designed to allow a user to enter an integer value within a specific range. The code prompts the user with a message that explains the limits of the valid range of values, but it does not force the user to enter legal values. We have examined a number of approaches for dealing with this problem. One approach is to place an assert statement in the getValue function to terminate the program when an illegal input occurs. An alternative approach is to put a loop inside the getValue function that prompts the user repeatedly until a valid value is received. Neither of these approaches is satisfactory, because they force the user to adopt a specific approach to dealing with the error. If you compare the execution of a program with the operation of a business, you will notice that both consist of a hierarchy of classes and functions. In a business, we expect the people in the upper layers of the company (managers) to set policies and the…arrow_forwardWrite the definition of a void function that takes as input two parameters of type int, say sum and testScore the function updates the value of sum by adding the value of testScore. The new value of sum is reflected in the calling environment.arrow_forward

Perform the following steps: In main.cpp, update the program to use the Board class. Remove the call to boardClear; the default constructor will be called automatically when you declare a variable of the Board type. Change every call to a function in the Board module to use dot notation. Reminder: If your Board variable is named my_board, then using dot notation, you should call the print member function, which takes no parameters, as follows: my_board.print(); Add a new load command to a game from a data file. It should ask the user for a file name and then load the game board from a file with that name. Note: If you used the Assignment 2 solution provided, your program already has this. Hint: The relevant code will look something like this: else if(move_string == "load") { string filename; cout << "Enter the file name: ";…arrow_forwardSo form code should be established in a functional way and outcome also.arrow_forward

If i have 4 Student objects how can i print the information for the specific object given one parameter about the class, like the students Idnumber. What i came up with was making a checkId void function that takes the user input and runs an if else chain checking if the Id belongs to student 1-4 then printing the details of that classes object with the void function print. ideally i would want the if-else chain in the checkId function to call the print( student1-4) class object but im not sure how to properly do that. i dont think this is the best way to go about it, if you have any recommendations or alternatives please help me out.arrow_forwardDon't put up wrong answer.
