A program contains three functions named main, calcGross, and displayGross. Two of the functions—main and calcGross—declare a variable named pay. The pay variable name also appears in the displayGross function header. When the computer processes the statement pay = hours * rate; in the calcGross function, it multiplies the contents of the hours variable by the contents of the rate variable. It then stores the result in which function’s pay variable? 

a. CalcGross

b. DisplayGross 

c. Main 

d. None of the above because you can’t have more than one memory location with the same name
