outfile.open("travel.txt");

Suppose you have the following code: ofstream outfile; double distance = 375; double speed = 58; double travelTime; What C++ statement would you have to include to open the file travel.txt using the variable outfile.

outfile << distance << speed << endl;

Suppose you have the following code: ofstream outfile; double distance = 375; double speed = 58; double travelTime; What C++ statement would you have to include to write out the values of the variables distance and speed into the output file.

False (only true for passing by value. When you pass by reference you must pass a variable)

The corresponding actual parameter in function call when you pass by reference or value can be an expression, a variable, or a constant value.
