1) Is the following a header or a prototype and what information does it convay?
  int fxxx(void)

Answer: Header for function fxxx: takes nothing, returns an int.
        Has not semicolon at the end.

2) Correct the following header and fefinition:
Bad header                          Fixed header
void fyy(void);                     int fyy(void)
                                    {
  printf("Welcome to class.\n");      printf("Welcome to class.\n"); 
  return (0);                         return (0);
                                    }

3) What are each of the following and what information does each convay?
a) float fabc(int, int, float); // proto:takes 2 ints, 1 float, returns flaot
b) int fmno(int ii, int dd, float rr) // header: takes 2 ints & assign to ii and dd, 
                                      // takes 1 float asigned to rr, 
                                      // returns int
c) return(tt*dd*rr); // multipy tt dd and rr
                     // returns result to calling function

4) The following lines are in main of a program:
    aa=6;
    bb=7;
    cc=fxyz(aa,bb); 
  The following lines are in the body of the funciton fxyz;
    {
      return (mm-nn);
    } 
a) What is the prototype for function fxyz?
  int fxyz(int, int);
b) What is the header for function fxyz?
  int fxyc(int mm, int nn)
