These are the steps you should do for the C++ Program: 1.- Modify the code so that the variables  and  are entered by the user on the keyboard. Move the code of lines 16 and 17 to a function called fEnterData (....) that returns v0x and v0y. 2.- Move the code of lines 18 to 26 inclusive to a function called fShowInitials (....). 3.- Move the code of lines 28 to 40 inclusive to a function called fComputeTrajectory (....). 4.- Move the code of lines 46 to 110 inclusive to a function called fGenerateGraphic (....).
