Chapter 3, Problem 1.7AYK

Question: State whether the following are valid switch statements. If not, explain why. Assume that n and digit are int variables. a) switch (n <= 2) { case 0: cout << "Draw." << endl; break; case 1: cout << "Win." << endl; break; case 2: cout << "Lose." << endl; break; }   b) switch (digit / 4) { case 0, case 1: cout << "low." << endl; break; case 1, case 2: cout << "middle." << endl; break; case 3: cout << "high." << endl; }   c) switch (n % 6) { case 1: case 2: case 3: case 4: case 5: cout << n; break; case 0: cout << end1; break; }   d) switch (n % 10) { case 2: case 4: case 6: case 8: cout << "Even"; break; case 1: case 3: case 5: case 7: cout << "Odd"; break; }

Orders for a stock trading system are coded as follows from left to right:1. The first character is 'B' for a "buy" order, 'S' for a "sell" order2. The number of shares to buy or sell3. The stock ticker symbol in all uppercase letters for a "buy" order or all lowercase letters for a "sell" order4. If the order is a "limit" order with a specific buy/sell price, the requested price is in pennies, otherwise the price should be omitted and the order will be a market order at the current asking price for the stock5. If the order is a "limit" order with an expiration time, the character 'T' followed by the number of minutes until the order expires should no longer be executedNote that the order code may only contain letters and numbers. (No comma, hyphen, etc)What would the code be to sell 8000 shares of Veteran Technology Solutions stock (ticker symbol: VTS) at the current market price?

v2 Question 6 What situation calls for a switch statement? Group of answer choices Use a switch statement when the switch statement is inside the main program. Use a switch statement when a for statement can not be used. Use a switch statement when a selection is in a repitition statement. Use a switch statement when a single control value determines which of several possible actions is to be taken. Use a switch statement when a selection is outside of repitition statement.

Write a single C statement corresponding to each of the following tasks: Declare x and y as float variables with the values of 8 and 20 respectively. Print the value for variable volume in two floating point. Define a constant called POINT with a value of 17. Print the message STAY SAFE!! on the terminal screen starting on a new line. Declare and initialize a double variable named salary.

THIS PROGRAM MUST BE WRITTEN IN C++! Your customer needs an automated system to patrol the highways. The job of the system is to collect the following information on vehicles traveling down a certain stretch of highway: license plate number, current speed, and speed limit. A program is required to determine if a speeding ticket is needed for each set of data. Ticket will only be issued when number of miles per hours (mph) over the speed limit is at least 5 mph. Ticket prices are calculated as follow: base + fee * <number of mph over the speed limit>. The base is always $150 and the fee per mph over the speed limit is varied according to number of mph over the speed limit. The fee per mph over the speed limit is $5 when number of mph over the speed limit is no more than 20 mph. However, the fee per mph over the speed limit is $10 when number of mph over the speed limit is between 20 mph and 50 mph. In addition, a ticket of $1000 is automatically given to vehicle when number of mph…

CHALLENGE ACTIVITY 4.4.5: Multi-branch if-else statements: Print century.   Write an if-else statement with multiple branches.If year is 2101 or later, print "Distant future" (without quotes). Otherwise, if year is 2001 or greater, print "21st century". Otherwise, if year is 1901 or greater, print "20th century". Else (1900 or earlier), print "Long ago".Sample output with input: 1776 Long ago

2a - Determine the weakest precondition for the following sequence of expressions. Pleaseprovide all your work including calculations, logic implications if any applies, and final answer.(10 points){ ? } a = 4 * (3 * b - a); b = 4 * a - 6; { b > 10 }2b - Determine the strongest precondition for the following if-else statement. Please provide allyour work including calculations, logic implications if any applies, and final answer. (15 points){ ? } if (x > y) then y = 2 * x - 1 else y = 3 * x + 1; {y>7}

Below are two basic blocks of code. Variables used include w, x, y, and z. For each block, determine which variables local to the block are live and which are dead as the statements execute (this is not global liveness analysis). 1.        x = 3;        y = 4;        z = 5;   2.         x = y + z;        y = x * z;

Consider the following four expressions: (a < 10) & (a > 10) not(a == 10) (a < 10) | (a >= 11) (a < 10) | (a > 10) Assume that a is an integer type variable. Three of these expressions are equivalent to each other, meaning that they will produce the same logical TRUE or FALSE result regardless of the value of a.  One out of four will not produce the same result as the other three. Which one is it?       (a < 10) | (a > 10)     (a < 10) & (a > 10)     (a < 10) | (a >= 11)     not(a == 10)
