between the two.
2. What is the difference between system software and application software?
3. Why must programs written in a high-level language be translated into machine
language before they can be run?
4. In C++, to display data on your monitor you use the << operator. What do you call this
operator?
5. What is wrong with this program and how you fix it so it compiles?
int main()
}
// A crazy mixed up program
return 0;
#include <iostream>
cout << "In 1942 Columbus sailed the ocean blue.";
{
using namespace std;
6. A program has the following variable definitions.
long miles;
int feet;
float inches;
Write one cin statement that reads a value into each of these variables.
7. Write C++ statements using combined assignment operators to perform the following:
a) Add 6 to x
b) subtract 4 from amount
c) Multiply y by 4
d) divide total by 27
e) store in x the remainder of x divided by 7
8. Complete the following table by writing the value of each expression in the Value column
EXPRESSION VALUE
----------- -----
28/4 - 2
6 + 12 * 2 -8
4 + 8 * 2
6 + 17 % 3 - 2
2 + 22 * (9 - 7)
9. The following program ues an if/else if statement to assign a letter grade
(A,B,C,D, or F) to a numeric test score. THE PROGRAM HAS ERRORS. Find as
many as you can.
#include <iostream>
using namespace std;
int main() {
int testscore;
cout << "Enter your test score and I will tell you \n";
cout << "the letter grade you earned: ";
cin >> testscore;
if (testscore < 60)
cout << "your grade is F.\n";
else if (testscore < 70)
cout << "your grade is D.\n";
else if (testscore < 80)
cout << "your grade is C.\n";
else if (testscore < 90)
cout << "your grade is B.\n";
else
cout << "THAT IS NOT A VALID SCORE.\n");
else if (testscore <= 100)
cout << your grade is A.\n");
return 0;
}
10. Write a program that asks the user to enter two numbers. The program should use the
conditional operator to determine which number is the smaller and which is the larger.
11. Write a program that reports the contents of a compressed-gas cylinder based
on the first letter of the cylinder's color. The program input is a character
representing the observed color of the cylinder: 'Y' or 'y' for yellow, 'O'
or 'o' for orange, and so on. Cylinder colors and associated contents are as
follows:
Orange ammonia
Brown carbon monoxide
Yellow hydrogen
Green oxygen
Your program should respond to input of a letter other than the first letters
of the given colors with the message, "contents unknown."
12. Write a program that uses a "for" statement to calculate the average of
several integers. Assume that the last value read is the sentinel value
99999. For example, 10 8 7 13 9 9999 indicates that the program should
calculate the average of all the values preceding 9999
13. Assume "value" is an integer variable. If the user enters 3.14 in response to the following
programming statement, what will be stored in value?
int value;
cin >> value;
a) 3.14
b) 3
c) 0
14. You studied Type Casting in Chapter 3. Type casting allows you to perform manual data type
conversion.
Assume the following definitions:
int a = 5, b = 12;
double x = 3.4, z = 9.1;
What are the values of the following expressions?
a) b/a
b) x * a
c) static_cast<double>(b/a)
d) static_cast<double>(b) / a
e) b / static_cast<int>x;
15. cout object provides a way to format the data that is displayed on the screen. To format data,
you include the header file <iomanip>. To set the field width, you use the stream manipulator setw.
See Chapter 3. For example, if you like to display the number 15 in a field of width 5 spaces, you
would write
int number = 15;
cout << setw(5) << number;
This will display the number in a field 5 spaces wide, right-justified.
Write cout statement with stream manipulators that perform the following:
a) Display the number 34.789 in a field of 9 spaces with 2 decimal places of precision
b) Display the number 67 left justified in a field of 7 spaces.
16. Indicate whether the following statements about relational expressions are correct or incorrect.
a) x <= y is the same as y > x
b) x != y is the same as y >= x
c) x >= y is the same as y <= x
17. Rewrite the following code using a do-while statement with no decisions in the loop body:
sum = 0;
for (odd = 1; odd < n; odd = odd + 2)
sum = sum + odd;
18. What three things do you need to do to use a function in your program? Explain each one of them
giving examples.
