How do i write these in a flowchart:

ConverterMenu1 cm1 = new ConverterMenu1();
CurrencyConverter cc = new CurrencyConverter();
MeasurementConverter mc = new MeasurementConverter();

Please help me quick!

Hmm... Do you know what flowchart is? What in the flowchart you are asking to do is the step-by-step of the flow starting from calling a method until it ends or returns.

By the way, no one would be able to guess what ConverterMenu1 class looks like but you. And I believe no one would just do it for you. You are supposed to do it, and we may help you to correct or direct you to the right way...

There is nothing to flowchart.
You have posted three assignment statements.
