Question 1

Consider the following program:

#include
#include
#include

using namespace std;

int main()

{
int num1;
int num2;

cout << fixed << showpoint << setprecision(2);

cout << “Enter two integers: “;
cin >> num1 >> num2; cout << endl;

if (num1 != 0 && num2 != 0)
cout << sqrt(abs(num1 + num2) + 0.5) << endl;
else if (num1 != 0)
cout << floor(num1 + 0.5) << endl;
else if (num2 != 0)
cout << ceil(num2 + 0.5) << endl;
else
cout << 0 << endl;

return 0;
}

a. What is the output if the input is -23 8?
b. What is the output if the input is 12 32?
c. What is the output if the input is 15 0?
d. What is the output if the input is 0 -36?
e. What is the output if the input is 0 0?

Question 2

Write the definition of a function that takes as input the three numbers. The function returns true if the first number to the power of the second number equals the third number; otherwise, it returns false. (Assume that the three numbers are of type double).

Question 3

Write C++ statements that do the following:

1. Define an enum type, birdType, with the values PEACOCK, SPARROW, CANARY, PARROT, PENGUIN, OSTRICH, EAGLE, CARDINAL, and HUMMINGBIRD.
2. Declare a variable bird of the type birdType.
3. Assign CANARY to the variable bird.
4. Advance bird to the next value in the list.
5. Decrement bird to the previous value in the list.
6. Output the value of the variable bird.
7. Input value in the variable bird.
   

Question 4

Write C++ statement(s) to do the following:

1. Declare an array alpha of 50 components of type int.
2. Initialize each component of alpha to -1.
3. Output the value of the first component of the array alpha.
4. Set the value of the twenty-fifth component of the array alpha to 62.
5. Set the value of the tenth component of alpha to three times the value of the fiftieth component of alpha plus 10.
6. Use a for loop to output the value of a component of alpha if its index is a multiple of 2 or 3.
7. Output the value of the last component of alpha.
8. Output the value of the alpha so that 15 components per line are printed.
9. Use a for loop to increment every other element (the even indexed elements).
10. Use a for loop to create a new array, diffAlpha, whose elements are the differences between consecutive elements in alpha.

Question 5

A car dealer has 10 salespersons. Each salesperson keeps track of the number of cars sold each month and reports it to the management at the end of the month. The management keeps the data in a file and assigns a number, 1 to 10, to each salesperson. The following statement declares an array, cars, of 10 components of type int to store the number of cars sold by each salesperson:

int cars[10];

Write the code to store the number of cars sold by each salesperson in the array cars, output the total numbers of cars sold at the end of each month, and output the salesperson number selling the maximum number of cars. (Assume that data is in the file cars.dat, and that this file has been opened using the ifstream variable inFile.)

Question 6

Suppose that you have the following definitions:

struct timeType { int hr; double min; int sec; };

struct tourType { string cityName; int distance; timeType travelTime; };

1. Declare the variable destination of type tourType.
2. Write C++ statements to store the following data in destination: cityName—Chicago, distance—550 miles, travelTime—9 hours and 30 minutes.
3. Write the definition of a function to output the data stored in a variable of type tourType.
4. Write the definition of a value-returning function that inputs data into a variable of type tourType.
5. Write the definition of a void function with a reference parameter of type tourType to input data in a variable of type tourType.
