What would be the output in Self-Test Exercise 15 if the first line were changed to the following?
int firstChoice = 3;
15. What output will be produced by the following code, when embedded in a complete
int firstChoice = 1;
switch (firstChoice + 1)
{
case 1:
cout << “Roast beef\n”;
break;
case 2:
cout << “Roast worms\n”;
break;
case 3:
cout << “Chocolate ice cream\n”;
case 4:
cout << “Onion ice cream\n”;
break;
default:
cout << “Bon appetit!\n”;
}

- What is output from the following code: TRACE FIRST: double *w; //Line 1 w =new double[5]; //Line 2 for (i = 0; i < 5; i++) //Line 3 { w[i] = pow(i, 2.0); //Line 4 cout << w[i] << " "; //Line 6 } cout << endl; //Linearrow_forwardLet's modify the program from this section so that the user can supply the interest rate. For very small interest rates, it may take a very long time for the balance to double. Assume the user can't wait for more than twenty years. Stop adding interest when the balance has doubled or twenty years have elapsed. 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 finaldoubleTARGET=2*INITIAL_BALANCE; doublebalance=INITIAL_BALANCE; intyear=0; Scannerin=newScanner(System.in); System.out.print("Interest rate in percent: "); doublerate=in.nextDouble(); // TODO: Count the years required for the investment to double // but no more than 20 years /* Your code goes here */ System.out.println("Year: "+year); System.out.printf("Balance: %.2f%n", balance); }arrow_forwardWrite a program that simulates flipping a coin to make decisions. The input is how many decisions are needed, and the output is either heads or tails. Assume the input is a value greater than 0. Ex: If the input is: 3 the output is: headstailsheads For reproducibility needed for auto-grading, seed the program with a value of 2. In a real program, you would seed with the current time. In that case, every program's output would be different, which is what is desired but can't be auto-graded. Note: A common student mistake is to call srand() before each call to rand(). But seeding should only be done once, at the start of the program, after which rand() can be called any number of times. Your program must define and call the following function that randomly picks 0 or 1 and returns "heads" or "tails". Assume the value 0 represents "heads" and 1 represents "tails".string HeadsOrTails() #include <iostream>#include <cstdlib>using namespace std; /* Define your function here */…arrow_forward

The player sorts her hand and says whether it includes the King of Hearts. Repeat 4 times so all the cards are dealt eventually. Internally, the player should return true or false without writing to the console. In response, the dealer should write on the console, "You won!" or "You loose again." Also create a unit test for the win and loose cases.arrow_forward
- hello, i am having problems with this hw question, Explain the problem with the following code: int a[] = {1, 2, 3, 4, 5}; a[5] = 10; cout << a[5] << endl;arrow_forwardThis is in JAVA. Which expressions for YYY and ZZZ correctly output the indicated ranges? Assume int x's value will be 0 or greater. Choices are in the form YYY / ZZZ. if(YYY){// Output "0-29"} else if (ZZZ) {// Output "30-39"}else {// Output "40+"} A. x < 29 / x >= 29 B. x < 30 / x >= 30 C. x < 30 / x < 40 D. x > 29 / x > 40arrow_forwardTHIS IS IN JAVA Given x = 1, y = 2, and z = 3, how is the expression evaluated? In the choices, items in parentheses are evaluated first. <pre><code>(x == 5) || (y == 2) && (z == 5)</code></pre> A. false OR (true AND false) --> false OR false --> false B. false OR (true AND false) --> false OR true --> true C. (false OR true) AND false --> true AND false --> false D. (false OR true) AND false --> true AND false --> truearrow_forward
