Can return type alone tell them apart?

Short answer. No.

Which area does area(4, 6) call?

The two-parameter rectangle version.

Remember

Same name, different parameters
Return type alone is not enough

Can two functions share one name? In C plus plus, yes. Both are named area. One argument calls the square version. Two call the rectangle one. This prints twenty five. Same name, different parameters. Return type alone is not enough.

This clip is from the full lesson: Functions in C++: Overloading, Default Arguments and Inline — 7 minutes, with the tables, the quick answers and the whole lesson in text.

Useful for: CBSE Class 9 Information Technology (402), GSEB Std 12 Computer Studies, NIOS Secondary Data Entry Operations (229), NIOS Senior Secondary Computer Science (330)
