Free Response Section (write the correct C++ source code for each situation. 25 points)

26-28. (3 pts.)Write a statement to declare a variable as an int .

29-31. (3 pts.) Using the same variable in question 26, use the assignment operator to set itsinitial value to 0.

32-34. (3 pts.) Write a statement that will add 1 to the value of the variable in question #29.

35-38. (4 pts.) Write an if statement and other necessary line(s) to check to see if the value in question #32 is equal

to 5. And if so, assign that variable to 0.

39-44. (6 pts.) This problem is independent of all others in the Free Response Questions.

Write several lines of C++ to give discount price on a ticket basedon the age of the senior.

45-50. (6 pts.) This problem is independent of all others in the Free Response Questions.

Write only the function that returns a bool to determine a situation. For example:

the sum of two angles is complimentary if they total 90 degrees. (a similar code problem on final exam)

If so, return true, otherwise, return false. Don’t forget to return the values. Use this given signature:

bool isComplementary(int angle1, int angle2)

{
