why no response to my cin input ?

Anonymous_Banned275

Here is my FIRST usage of cout / cin using QT console.

My code :

  char i;
    std::cout << " Hello...\n";
    std::cout << "Enter password: ";
    std::cin >> i;
    std::cout << "Password entered is " << i;

and its output

Hello...
Enter password:q

no response AFTER "q and enter key is pushed" - using debug console .

What simple thing / setting am I missing ?

There is a "Enter" key on keyboard I am pushing....

two things:

insert std::flush after your "Enter Password" prompt
make i an std::string

As for now seeing output, you should see output only after flushing cout.

@AnneRanch
Actually, after std::cout << "Enter password: "; is not where you need your std::flush() or std::endl. Because that is followed by a std::cin >> i; it auto-flushes, as you see in the output you show. You need it after your std::cout << "Password entered is " << i;, e.g.

std::cout << "Password entered is " << i << std::endl;

What exactly do you mean with "Qt console"? I assume that you are using Qt Creator here. Is that right? Do you mean the integrated output pane of Qt Creator? Do you set Qt Creator to run the app in a separate terminal? What operating system are you using? Windows 10?

In addition to the answers so far, this might play a role if @JonB's answer does not help so far.

You must tick run in terminal if you create CMake project with C++
