Whats this? I can't read doubles any more!

Code:

---

#include <stdio.h>

int main()
{
    double b;
   
    scanf("%f", &b);
    printf("%f\n", b);
   
    system("pause");
    return 0;
}

I feel so weird, I have been programming for years and I'm having such a simple problem, when I input a number, the printed number is garbage.

I tried this code in a different computer and in a diferent compiler and it still won't work! if I use a float instead of a double it does work WTF.

Have a walked into the twilight zone or something?

That's because %f is for reading floats and not doubles.

Code:

---

scanf( "%lf", &b );

Quzah.

I can't beleive this, I have been programming for 4 years and I learn this until know? >_<

In my defense I bearly ever use C >_>

Thanks man, you have made it possible for me to sleep tonight.

Yes it's quite annoying having the *printf and *scanf functions use similar, but different, format specifiers.

Another reason to use gcc with say -Wall, which will tell you when your *scanf and *printf conversion strings don't match the parameters.
