"i made mistak"
I trust that one's on your list.
You also made the mistake of not reading and/or not following the clear instructions on how to post source code - there's another.
And you made the further mistake of not previewing your code before you posted it - there's another.
So there you go - 3 more guaranteed fully professional items for your list!
Two more for your list:
Writing programs in one languages as it it were another (eg, you seem to be trying to write a BASIC program in 'C'...)
Unconsidered, liberal use of 'goto' is usually a whole nest of bugs just waiting to happen...
