Chapter 5, Problem 16SA

(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs increment the counter variable that's keeping count of the 1s that occur; and so on. finally display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.

in the following program please use string data types and string functions. use enum types. for loops with enum types, etc. Thank you.  Write a C++ program that takes a date in the following format: December 24th, 2021 and extracts the day, month, and year as 3 integers. Your program should have and use at least the following functions: (a) Write a function getDate that prompts a user to enter a date as a string and returns it. (b) Write a function extract that takes as its parameter a date and returns the day, month, and year as 3 integers. (Hint: you can use the function isdigit(c) that returns true if c is a digit character and false otherwise.) (c) Write a function convertDigits that takes as its parameter a string of digits and converts it to an int. (Hint: to convert a digit character to a digit number use static cast (’d’) - static cast(’0’) where d is 0, 1, ..., 9) (d) Write a function convertMonths that takes as its parameter a month as a string and returns a corresponding…

The language we are using here is in Racket.  Please enter the following code: (cond ((equal? 16 3) (+ 3 8))       ((equal? 16 8) 12)       (else (* 6 3))) Write the return value for the above code. If replacing all of the 16's in the above code with 8, what is the return value?  What about replacing the 16’s with 3? What does the cond function do?

Consider the following recursive function:    void exercise(int x)    {        if (x > 0 && x < 10)        {            cout << x << " ";            exercise(x + 1);        }    }        What is the output of the following statements?        a. exercise(0);        b. exercise(5);        c. exercise(10);        d. exercise(-5);

Description   F(x) = x + 1 G(x, y) = x + y Please write a program to calculate the value of composite of F and G   Input   Input will be the composite of F and G. The parameter of F and G are integer only.   Output   An integer represent the value of function.   Sample Input 1  F(G(1,F(3))) Sample Output 1 6

The correct prototype for the following function heading is void F1(int &p1, double &p2, bool &p3)

Suppose you want to select a random number from the following sequence:0, 5, 10, 15, 20, 25, 30What library function would you use?

PROBLEM: Write a program that prompts the user to input coefficients A, B, and C of a quadratic equation in general form (Ax^2 + Bx + C = 0) to determine the nature of the roots of the quadratic equation. SPECIFICATIONS: - You may only use the codes that we studied under our lectures - All lines of codes should have a comment. - Save your cpp file as Surname - PE (Example: Pangaliman - PE.cpp) TEST CASES: If a user inputs the three coefficients of a quadratic equation: Enter A: 1 Enter B: 7 Enter C: 12 Result: The roots are real and distinct. If a user inputs the three coefficients of a quadratic equation: Enter A: 2 Enter B: 2 Enter C: 3 Result: The roots are complex and distinct.

What is the output of following code segment?
