[Solved] Compare inline function in std::sort()

Read more about C++11 at least (or C++14 or C++17), e.g. some good C++ programming book (any standard older than C++11 is obsolete, and C++11 has evolved a lot since its predecessors, so you should almost consider C++11 as a new programming language). Look also some C++ reference site. [](const string &left, const string &right) … Read more

[Solved] I tried try and catch for double but it didn’t work [closed]

It’s because when you enter a number and press Enter key, scan.nextInt() consumes only the entered number, not the “end of line”. When scan.nextLine() executes, it consumes the “end of line” still in the buffer from the first input which you have provided during the execution of scan.nextInt() . Instead, use scan.nextLine() immediately after scan.nextInt(). … Read more

[Solved] C++ operator precedence

The effect is as you write, but it’s achieved using a slightly different sequence: The post-increment has highest precedence, so it’s evaluated first. However, its return value (which is processed by further operators) is the value of iter before the increment. Dereference is evaluated next, returning pointer to which the non-incremented value of iter was … Read more
