When I compiled my code on Visual C++ 6, I don't have any errors,
but when I post my task to the jungle, I have:

You tried to solve problem 1030. Your solution on C++ was compiled
with
the following errors:

335461
335461.obj : error LNK2019: unresolved external symbol _fcvt
referenced in
function _main
temp/335461.exe : fatal error LNK1120: 1 unresolved externals

May be you know what is it? My mail: fmb2002@bk.ru
