1. What are each of the following and what information do they convey?
   Code:                       // Answer:
a) float ccc(int xx, float yy) // header for function ccc: takes an int (assigns to xx), and a float (assigns to yy)
b) int xxx(void);               // prototype for function xxx: takes nothing, returns an int
c) void mmm( char, char, float, int; //  prototype for function mmm, takes 2 chars, float and int, and returns nothing

2. Which of the three fucntions in question 1 have return lines in their code bodies?
Answer: a and b

3. Correct the following that employs the same functions:
main                                                    int main(void)
{                                                       {
  float AA                                                 float AA;
  float BB = 9.43;                                         float BB = 9.43;
  float CC = 4.543;                                        float CC = 4.543;
  int   DD = 5;                                            int   DD = 5;
  char  EE = 'b';                                          char  EE = 'b';

  AA = ccc(BB);                                            AA = ccc(DD,BB);
  BB = xxx(DD);                                            BB = (float)xxx();
  CC = mmm(AA,BB,CC);                                      mmm(EE,EE,AA,DD); 
  printf("Values are: %d, %d, %d \n", AA, BB, CC);         printf("Values are: %d, %d \n", AA, BB); 
}

4. A variable bbb is declared before main as an int with value of 5.
   A variable bbb is declared in main as a float with value of 2.345.
   A function does not declare a variable bbb but performs a calculation and store it's result 7 in bbb.
   In main a printf statemnt outputs the value of bbb.
   What value is output and why?

Answer: The output is 7.000000.  Local declaration trumps global. Since funciton is called after the float
        declaration and assignment it reassigns the value, but the variable remains a float.

5. Create a new functions source file and header file containing neened informatino for 
   your user functions, and add two functions.  Write a program that employs the user
   functions in the new file.
