my c++ code is giving error syntax declaration

all the sed function have been declared.the error is on '{'

You appear to be defining a function (m2) inside a function (hang).

I think it would be better if the function prototypes (lines 6,7,8) appeared before any functions.

Oh, and when you make a comment in code, use //, not \

It allso helps if functions aren't nested inside one another. A modern IDE, like CodeBlocks, NetBeans, or Visual Studio, which can all be used for free, helps with gettting these kinds of syntax issues straightened out.
