There is a .h file that needs to work with these other two. Or, if one of those is the .h then I needs another .cpp file to fill the requirments of the lab. Thanks in advance.

STEP 2: Required Class Members

Explanation / Answer

he function main() should display the new, modified values of the resistor object, including the new min and max in-tolerance resistance values. cout
