"You can define a function inside another function”

Question

In C++ challenges, there is a question "You can define a function inside another function”, of which the right answer would be false. However what about the lambda expressions? They are both definable and callable inside functions.

Answer 1

I'm guessing that quiz was based on pre C++11 standards.

And perhaps the quiz poster was strictly referring to actual function definition.

Though by definition your statement that lambda expressions are definable and callable was correct.

Answer 2

Perhaps they should have described they are strictly referring to the normal function definition instead of making the people confused.

Answer 3

yes you can define function inside another function which is also called nested function
