C++ file not working?

Hey I just made a little c++ file and when i debug and build and stuff it works perfectly fine. But then i tried using the exe from the project's folder and it just shows the console but closes when i try to type in my cin part of the code. does anyone kno why?

try putting in cin.get(); more than once right after each other because sometimes that's what happens.

LOL I just started learning so i just made a celsius to fahrenheit converting program.
#include <iostream>

int main()
{
using namespace std;
int Celsius;
int Celsiuss;

cout << "Please enter a Celsius value: ";
cin >> Celsius;
Celsiuss = 1.8 * Celsius + 32;
cout << Celsius << " degrees Celsius is " << Celsiuss << " degrees Fahrenheit." << endl;
return 0;
}

like it works if i debug from microsoft visual but from like project's folder the exe doesn't work. it just shows the console and first line. When i type in the number and press enter it just closes.
