Scanf an integer - C

Hey.

Suppose I want to scanf an int - here it doesn't work if I just do:

Code:

---

int in;
scanf("%i", &in);

---

Why is it?
What's the difference between that and:

Code:

---

float f;
scanf("%f", &f);

---

Thanks in advance.

I'm not sure what you're getting at. Both of those seems to "work".

However, if you mean to only allow decimal input for the integer then it's better to use %d instead of %i since %i accepts inputs like 010 as octal (hence decimal 8, not 10), which is probably not what the user intended. Although %i is sometimes useful, especially for hex input in the for 0xab.

@John - we are now discussing this issue at the other thread.
Thank you!!!
