2. The scope of a variable
A) defines how long the variable exists during program execution
B) defines the distance from the variable to the end of the program
C) defines the way in which the variable can be used in the program
D) defines the part of the program that can see and use the variable
3. The storage class of a variable
A) defines how long the variable exists during program execution
B) defines the distance from the variable to the end of the program
C) defines the way in which the variable can be used in the program
D) defines the part of the program that can see and use the variable
4. Which of the following is not a storage class?
A) register
B) extern
C) default
D) static
5. Which of the following is the best choice for structured programming?

6. Write a recursive function to calculate the value of the function f given the definition below for the function. Assume that you receive one integer input x and return a long value. {16}
f(x-1) + x2 for x > 1
f(x) = 1 for x = 1
0 for x ≤ 0
7. Use the following code fragment to answer the questions below:
enum done toaster;
toaster = black;
switch (toaster) {
case burnt: printf(“ Burnt!”);
case black: printf(“ Oh, yuck!”);
case done: printf(“ Someone made “);
case light: printf(“ Toast?”);
case default: printf(“ Jam?”);
}
A) Write an enumerated type named done that would properly define the values for the variable toaster given the switch statement above. {6}
B) Give the result of executing the code fragment above assuming it compiles correctly. {8}
C) Using the syntax given below, write the remainder of the case for a value not such that the switch will print out the message “Broken?” when the value of toaster is not. {7}
switch (toaster) {
case not:
case burnt: printf(“ Burnt!”);
…
8. Define a structure type named donation that contains the following information: a unique 8-digit code, a blood type (A,B,O, or AB), an rH factor (+ or -), the date in dd/mm/yyyy form, and a location code (up to 20 characters). Also declare two variables of this new type. {11}
9.Write the interpretation of the declaration below in words. {10}
long (* fun1)(double, char *[]);
The variable fun1 is
10. Write the correct syntax for the prototype declaration of a function with an integer input and a string input which returns a pointer to a function with a float input and a void return value. {10}
11. Write a switch statement to print the astrological sign for a given date. Use the table below to write the cases. The switch must use both month and date information to correctly work. {12}
January 21 – February 19 Aquarius
February 20 – March 20 Pisces
March 21 – April 20 Aries
April 21 – May 21 Taurus
May 22 – June 21 Gemini

August 24 – September 23 Virgo
September 24 – October 23 Libra
October 24 – November 22 Scorpio
November 23 – December 21 Sagittarius
December 22 – January 20 Capricorn
