why does it compile but not run?

Expand Post »

Using Dev-cpp, a small program compiles but the resultant .exe file
does not run. From the DOS command, it runs. When I try from the
windows run command , it flashes but immediately goes away.

Re: why does it compile but not run?

C++ Syntax (Toggle Plain Text)
cin.ignore(); // this ignores one enter key
cin.ignore(); // this ignores one enter key

C++ Syntax (Toggle Plain Text)
system("pause"); 
// should use cin.ignore but you can use this
// it displays: "Press any key to continue..."
// and when you press any key, it continues...
system("pause"); 
// should use cin.ignore but you can use this
// it displays: "Press any key to continue..."
// and when you press any key, it continues...

or as veron was saying

C++ Syntax (Toggle Plain Text)
// Before using this make sure you have included: #include <windows.h>
Sleep(1000);
// the amount you put is in miliseconds, 1000 = 1 second
// this will wait the amount of time you put into before moving on.
// Before using this make sure you have included: #include <windows.h>
Sleep(1000);
// the amount you put is in miliseconds, 1000 = 1 second
// this will wait the amount of time you put into before moving on.

put that in, and you will press enter before the window closes..

atm it is running correctly but it doesent know you want it to wait till you want to end it, so you have to add that.

Re: why does it compile but not run?

Small programs usually run in command prompt...if you want it to have its own window, that's a different matter.

Re: why does it compile but not run?

C++ Syntax (Toggle Plain Text)
cin.ignore(cin.rd_buf()->in_avail());
cin.get();
cin.ignore(cin.rd_buf()->in_avail());
cin.get();

Slap that on the end of the code. This will do the following:
ignore all the available input from the cin (console) input buffer, then grabs a null terminated character (basically waits until you hit enter).
