c++ programming..

Hi, can you help me make a flowchart for the code below?

{ Calculator calculator;

textcolor(2);

cout << "--------------------------" << endl; cout << "For special formula, type: " << endl; cout << " ohms law" << endl; cout << " power efficiency" << endl; cout << "To quit, type: " << endl; cout << " quit" << endl; cout << " exit" << endl; cout << "--------------------------" << endl;

while (true) { try { calculator.requestExpression(); } catch (...) { cout << "Error occurred." << endl; } cout << endl; }
