how do i write a program that ask user to enter a number, and then checks weather the number is prime or not.it should use a QInputDialog to get number from the user and QMessage to display the result.

i have created my projects, below is my main.cpp:

#include<QApplication>
#include<QMessageBox>
#include<QInputDialog>

int main( int argc, char **argv )
{
QApplication app(argc, argv);



return 0;
}


and below is .pro

Question1.cpp

Come on, stop posting your question in each thread! Instead of doing this try to read Qt Assistant or read books about Qt!
