Quiz 3
Monday, October 28, 1996
This quiz is 20 total points. Please write legibly. If I can't read
it, I can't grade it. You have until 5 minutes after the class period
ends to finish.
Good luck.
- (5 points) Write the struct declaration for a
structure called ``Computer'' which has four member variables: an
integer disk_size, an integer monitor_size, a
character model_type, and a double total_price.
- (5 points) Rewrite the following function to use switch statement
instead of a nested if-else statement. Your code should have no if
statements.
int foo(int number, int value)
{
if (number == 1) {
value = value * 2;
} else if (number == 3) {
value = value + 10;
} else if ((number == 4) || (number == 6)) {
value = value * value;
} else {
value = 17;
}
return value;
}
- Over -
- (5 points) What does the following code display to the screen?
#include<iostream.h>
int bar(int number, int value)
{
if ((number == 1) && (value++ > 0)) {
return value + 10;
} else {
return value;
}
}
int main()
{
cout << bar(0, 0) << endl;
cout << bar(1, 0) << endl;
cout << bar(0, 1) << endl;
cout << bar(1, 1) << endl;
}
- (5 points) Rewrite the following function to use a while or
do-while loop instead of a for loop.
int factorial(int n)
{
int counter, fact = 1;
for(counter = 1; counter <= n; counter++) {
fact *= counter;
}
return fact;
}
