COSC 1415 Practice Test #2
conditions, while loops, for loops

Using the variable declarations below, what will the following conditions evaluate to?

int Apple = 5, Pear = 8, Grape = -4;

1. (Apple > Grape)

2. (Pear > Grape && Apple < Pear)

3. (Grape != 3 || Pear != 8)

4. (!(Apple >= Apple) && !(Grape == (Pear - 12)))

5. (Pear = Grape)

How many iterations will the following for loops execute?

6.  for (int X=1; X<=3; X++)    

7.  for (int X=5; X>=0; X--)    

8.  for (int G=0; G<8; G++)    

9.  for (int Yellow=1; Yellow<=20; Yellow=Yellow+2)    

10.  for (int X=5; X>8; X++)    

11. What C++ statement will allow your program to show the calendar for 2008? 

What will the following assignment statements evaluate to assuming the variable declarations below?

int J = 1, K = 0, L = -1, M = 4, N = 3;

Assignment Statement Resulting Value of the Variable Q
Q = 8 % M + 15; 12.
Q = 2 + 2 * M / 2 - 2; 13.
Q = N * 2 + M * 4 - J / J; 14.
Q = (N * 8) % 5 - L; 15.

Here's some more difficult problems to really test your skill:

float A = 1, B = 10;
while (A < 10)
{
   if (A == B) cout << A;
   A++;
   B = B - 0.5;
} 

16. What will this output?


for (int X=99; X>1; X--)
{
   if (X==4 || X == 3) cout << X * 2;
} 

17. What will this code output?


for (int X=1; X<100; X=X*2)
{
   if (X == 10) cout << "yes";
   if (X == 20) cout << "no";
}

18. What will this code output?


for (int Y=1; Y<5; Y=Y+2)
{ 
   cout << Y-1;
}

19. What will this code output? 


int Apple=5, Pear=0;
while (Pear != Apple)
{
  cout << Pear;
  Apple = Apple - (Pear + 1);
  Pear = Pear + 1;
}

20. What does this code output? 


bool G = true;
short int F = 0;
while (G)
{
  cout << F + 1;
  if (F > 5)
    G = false;
  F++;
}
cout << F + 1;

21. What will this output?


float J = 1.5;
if (J > 2)
  cout << "J";
  cout << "K";

22. What will this output?
