Answer / guest
Name mangling is the rule according to which C++ changes
function's name into function signature before passing that
function to a linker. This is how the linker differentiates
between different functions with the same name.

Compilers need name mangling to support/implement function
overloading.

Answer / achal ubbott
It is by name mangling that a c++ compiler is able to
support function overloading.It is the way of
differentiating functions based on their name,number and
order and type of parameters. Unfortunately ISO has not set
any standard procedure for mangling names. So different c++
compiler vendors implement it in different ways.
