php code - Bekijk de code zonder highlighting - Klap code in 
  1. #include <iostream>
  2. #include <string>
  3. using namespace std;
  4.  
  5. int main ()
  6. {
  7.   int i;
  8.   cout << "Please enter an integer value: ";
  9.   cin >> i;
  10.   cout << "The value you entered is " << i;
  11.   cout << " and its double is " << i*2 << ".\n";
  12.   cin.get();
  13. }

yoo sima-leden, ik ben begonnen met c++ en het lukt me aardig om wat basis stuff uit te werken
maar ik loop vast als ik dit execute, ik geef een nummer in en het schermpje sluit, nochtans probeer ik dit te voorkomen met cin.get();
bij andere scriptjes werkte dat perfect, maar hier niet; met of zonder is er geen verschil

Is er iemand die weet hoe ik kan voorkomen dat het (dos-)schermpje sluit?

Avatar van MothZone PHP ver gevorderde opnieuw cin.get() doen

als je geen "cin >>" doet is 1x cin.get() genoeg, anders 2x

Avatar van Voldemort PHP ver gevorderde Gewoon aan het einde (van je main functie) doen:

return 0;

Dat werkt hier ook, je programma eindigt, maar de output blijft (hier onder Linux toch). Nu er toch een topic over C++ is:

ik heb geen windows.h bestand op Linux. Ik zocht en ik lijk er 1 te hebben in:

/usr/include/directfb-internal/core/

Dus zorg ik dat ie daar dat windows.h uithaalt, maar dan krijg ik (g++):
