Using threads for time-consuming background calculations in C++ in Qt Creator

Using C ++, the Qt library, and Qt Creator, create a program that will allow you to perform time-consuming background calculations.

The application must allow pause or complete cancellation of the performed calculation (the following calculation must not restrict the application). Both calculations can run at the same time!

The progress of the calculation will be indicated with progress bar.

Implemented algorithms:

- recursive / iterative calculation of factorial from (any large) integer

- sequential algorithm of the Sieve of Eratosthenes to search for prime numbers on a specified range of integers.
