A Simple Question (I think)

Hey,
I'm learning C Programming at Uni and was given the following code to compile and try the program...

Code:

---

#include <stdio.h>                                                                       
main()                                                                                                                       
{                                                       

int pets;                                                       
int cats;       
int dogs;       

printf("\a How many pets do you have?\n");                               
scanf("%d", &pets);                                                       
printf("So, you have %d pets! How many of these are cats?\n", pets);        scanf("%d", &cats);       
printf("and how many dogs?\n", dogs);
scanf("%d", &dogs);       
printf("So, you have %d pets of which %d are cats and %d dogs!\n", pets, cats, dogs);

return 0;

}

Can someone explain why the window is closing before the final line is printed and how I stop this?

Thank you for your time,
Scott

I'd bet that it does print the final line, but it's so shortly before it closes the window that you don't see it.

From the FAQ:
Stop my Windows Console from disappearing everytime I run my program?

that makes sence, thank you very much for pointing out the article :)

so I'm guessing it would just be easiest to repeat

Code:

---

scanf("%d", &dogs);

---

after the last print so it thinks its waiting for another input?

thank you very much for your help, it's appreciated!

Yes, that would work - it's a bit excessive, but it'll do the job.

I'm so old that I'm used to running things from a command window rather than just clicking things in the IDE, so I usually just let the progra finish, but since I'm already in a command window, the text remains - I just get a C:\somedir> at the bottom of the screen.

ah great, just tried that, so no code changing needed, even better :D

thanks again for your help!

or you can put these at the end of your code right before the return command of the main function:

Code:

---

fflush(stdin);
getchar();

---

so the program waits for an additional ENTER at the end to close

In windows, system("PAUSE"); expects any key for the program to continue. This also automatically inserts the text (on a new line): Press any key to continue . . .

Never use fflush(stdin), its behavior is undefined.
