Very short code tt never work...please help

The code looks like this (got this from dev++ C tutorial):

Code:

---

#include <stdio.h>

main ()
{
int num1, num2;

printf("\nEnter first number ");
scanf("%d",&num1);

printf("\nEnter second number ");
scanf("%d",&num2);

if (num2 ==0) printf("\n\nCannot devide by zero\n\n");
else printf("\n\nAnswer is %d\n\n",num1/num2);

}

---

The problem is after the prog prompt me for the second no, and after I enter and hit the 'Enter' key, the whole program disappears - failing to print either the statements, "Cannot devide by zero" or "Answer is...".

Tried different compiler like Borland and also replacing scanf with getchar - and still get the same thing. Wat is wrong???

Thanks a zillion for your help.

Try this:

Code:

---

#include <stdio.h>

int main ()
{
int num1, num2;

printf("\nEnter first number ");
scanf("%d",&num1);

printf("\nEnter second number ");
scanf("%d",&num2);

if (num2 ==0) printf("\n\nCannot devide by zero\n\n");
else printf("\n\nAnswer is %d\n\n",num1/num2);

system("PAUSE");
return 0;
}

[EDIT]

Dammit, I always forget that the FAQ knows all.

try this.

Code:

---

#include <stdio.h>
#include <conio.h>

main ()
{
int num1, num2;

printf("\nEnter first number ");
scanf("%d",&num1);

printf("\nEnter second number ");
scanf("%d",&num2);

if (num2 ==0) printf("\n\nCannot devide by zero\n\n");
else printf("\n\nAnswer is %d\n\n",num1/num2);

getch();
}

I think that your console is not visible because you are not returning nothing to os.

this code works fine in turbo c++ 4.5 without any problem.

Wow. People, the only time the program pauses really is for input. So PLEASE use a standard function for input like getchar(). Then your program pauses and you don't even need to include an extra library.

>Dammit, I always forget that the FAQ knows all.
The FAQ even knows to include stdlib.h for the system function. ;)

Not everyone has Turbo C++ v.old as dirt. In fact, you shouldn't either unless you're working with legacy code that requires it.

You need a buffer flush and then call getchar:

Code:

---

#include <stdio.h>

int main ()
{
int num1, num2, ch;

printf("\nEnter first number ");
scanf("%d",&num1);

printf("\nEnter second number ");
scanf("%d",&num2);

if (num2 ==0) printf("\n\nCannot devide by zero\n\n");
else printf("\n\nAnswer is %d\n\n",num1/num2);

while ((ch = getchar()) != '\n' && ch != EOF);
getchar();
return 0;
}
