Urgent Programming C++ help please!

[Tds123]

ok so i am a new programmer to the 1396 team because our old programmer has recently graduated. He has taught me some things but i still do not understand how to use the C++ language to program. Especially since we have the new laptop/ driver station this year this puts a lot of pressure on me as to figure all this out and i am becoming very nervous about how i am going to get this robot to function this year ... whats on the electronics board of this robot is

4 jaguars because we are using 2 motors per gearbox this year

4 spikes... because we have 2 motors for a wench, 1 motor for a manipulator, and another motor for a dumper for the soccer balls..

I also do not how to assign the motors to a button on the control stick like how to turn the motors on and off using the spikes.. so if someone can help with that also that would be much appreciated... Please help someone
