Technicans a says the engine camshaft converts reciprocating motion of the piston into rotary montion for power output. technician b disagrees and says the crankshaft performs this function who is right?

It doesn't say what Technician B thinks, but I can tell you what the camshaft does and then you can decide who is right on your own. The camshaft is little metal rounded triangles above the piston that times when the intake and exhaust valve open and close.

Technician A is very wrong, the camshaft doesn't do that.

a variable of array type holds a reference of object

it stores 1st quantity value in index value 0 and this process will same till index value 9.
