So lambda functions are mostly used for doing simple things (like additions) without having to define a new function "add_numbers"? Also taking into account that i wont repeatedly use the same lambda function.

I really do not understand the "property" and the "setter". The "property" makes the attribute read-only, but the "setter" makes the attribute mutable. So if we want to use "property", why we need to introduce the "setter".

In the example, even if the order was salary and name, which is different from the way it is arranged in table, the code was executed. So here, if we interchange age and name, why is it showing incorrect!?

When dealing with propagation, if you set a <div> element to true, meaning it will use capturing, but set a child element, say <p>, to false so it uses bubbling, which event will take place first?

just asking. in C++, why do we need to define signed & unsigned integer? why don't we always use signed? it's better. we can freely assign plus and minus. so what's the catch of using unsigned?

While prototyping friend functions in a class is it necessary to always pass the address of the object as parameter?If so why is it that we have to pass address as parameter..In programs involving compositions we never used addresses...Why is the need for address of the objects while using friend?

How can I add an item at the end of the array? The most easy way (arr [5]=8) returns "out of range", and I suppose it's because first I instantiate it as "int [] arr=new int[5]", so it's out of the range. Can I amplify that range?
