[Solved] How can I double a time value in C++ [closed]

Question

Use ONE of the file-handling routines in C++ or C. Mixing FILE and ifstream is certain to cause problems.

ifstream input;
input.open("time.in");
input>> hrs;
input.get();
...

should do the trick.
If you want to be picky:

if (input.get() != ':') ... complain about bad input ...
