1] Each of the following blocks of code may or may not produce any output. Record any output to the right of the block of code. See Examples. If syntax corrections need to be made in order to make the code compile corretly, use a pen or different colored ink to make the corrections.!

If in doubt, plug it into the computer and test the block of code!

Assume the following declarations, at the top of main, for all.
int
   A = 10,
   B = 5,
   Temp;

Example 1
   A = 10,   <-- Correct , should be ;!
   B = 5;
cout << "Ex1: A = " << A << "     B = " << B << endl;
if (A <= B)
   B = A;
cout << "A = " << A << "     B = " << B << endl;

Ex1: A = 10 B = 5

A = 10 B = 5

Example 2
   A = 10;
   B = 5;
cout << "Ex2: A = " << A << "     B = " << B ;
cout << "     Temp = " << Temp << endl;
if (A > B)
   B = A;
else
   B = A - 5;
cout << "A = " << A << "     B = " << B << endl;

Ex2: A = 10 B = 5 Temp = ???

A = 10 B = 10

Example 3
   A = 10;
   B = 5;
cout << "Ex3: A = " << A << "     B = " << B << endl;
if (A > B)
   cout << "A > B\n";
else if (A == B);
   cout << "A = B\n";
else
   cout << "A < B\n";

Ex3: A = 10 B = 5
A > B

2] Anticipate the intended logic. Correct all of the errors in each of the following program fragments. Assume the following declarations, at the top of main, for all.
int
   A = 10,
   B = 5,
   Count,
   Sum;

if A = 10
cout << "A = " << A < < endl

A = 7;
if 3 < A < 10
   {
      A = A + 1;
      cout << "A = << A < < endl;
   }

Count = 0;
Sum = 0;
A = 50;
if (A < 0)
   Count = Count + 1
else if A = 0
   Count = Count - 1;
Sum = Sum + A;
cout << "A = << A << "   Count = << A << "Sum = << A << endl;

3] Those Labs labeled "Individual Assignment" are to be done separately by each individual. Using a pen, each individual is to print his/her name at the top of this document in the space provided and sign it. Those Labs labeled "Team Assignment" may be done as a team or individually. Using a pen, each individual on the team is to print print his/her name at the top of this document in the space provided and sign it. Submit only one copy of team assignments!
