Re: [algogeeks] help with o/p why 0 comes???
The output of the below code is also zero ,
key reason is floating point number are stored as *mantissa, exponent. *
float dec=1.00;
printf("\n dec=%d , float =%f",dec,dec);

Hi Shubham,
This may be because your final data type you have chosen for your output
is float, n the one which you are trying to print is of int data type (i.e. %d).
Suggestion : Try changing %d to %f and see whether it works for you or not?
Thanks & Regards,

Re: [algogeeks] help with o/p why 0 comes???
Ya, its looking like the problem of 'i686-apple-darwin11-llvm-gcc-4.2'.
For me as well it shows different outputs.

any clues .. why ?

Re: [algogeeks] help with o/p why 0 comes???
yup , it is showing
0
0
on ideone as well . so my gcc compiler is i686-apple-darwin11-llvm-gcc-4.2.
that can be the reason . from here it appears 0 is just a coincidence and
it depends on compiler implementation . C doesn't define any such behavior.

1.00 is the result which when read as %d takes the decimal value of
stored in memory - it will not be 1.00 or 0.
Since float is not stored as direct binary in memory as integer is
stored, instead there's a separate procedure for storing float as binary in
memory

I think this is because of type mismatch. You are enforcing your program to
read a floating point number in the way of reading a integer. And they have
totally different format. If you have -Wall turned on, you should see a
warning.
