QT creator 15.0 run in terminal for proper cout and cin functionality

Question

I want to make cin>> work in QT, so it's needed to use the external terminal, not the application output.

I followed all the instructions given in the previous answers about cin>> not working, but I can't make it work on QT creator 15:

I set: "run in terminal"
I de-select "show in application output when running"
I added the cmd.exe path in edit->preferences->environment->patch command

The terminal opens, but the only thing that is output is: Press to close this window...

My simple code:

#include <iostream> using namespace std; int main() { string a; cout <<"enter any string" << endl; cin >> a; cout << endl; cout << "I understood: " << a << endl; return 0; }

This isn't expected. Use your debugger to see what is happening. Set a breakpoint after the first cout and see what happens. — drescherjm

I added one breakpoint at every step from the first cout. The terminal is empty until the return 0 command when the message describes avive is output. Also creator application output remains with "debugging...." Line until "has finished with exit code exit code 0" comes at the return 0 command — Walter Balzarotti

I found the problem, you need to create a console project. A widget project is not allowed to output to the external terminal. — Walter Balzarotti

2 Steps are required to make Creator not redirect the console output to its internal console:

a) Go to the Build & Run Settings of your project, select Run, in the Run Section, select "Run in terminal"

b) Go to the Application Output Pane. There is a wheel indicating the settings for the Aplication Output. Press it and select the "Terminal" section. There disable "Use internal terminal".

That's all. Pretty unintuitive:-)
