There are tools available that will convert *some* Mathematica
code to C++ code or C code. But I emphasize some. If the
Mathematica code involves specialized Mathematica functions,
they will not be converted to C++ nor is it reasonable to expect this.

Any compiled code that is appropriately optimized and debugged
with optimal algorithms can be expected to run faster than
Mathematica. But converting Mathematica code to something that
is optimal and can be compiled is far from a trivial task. If
you've no experience with C++, it is quite unlikely you will be
able to achieve the improvement you desire. It is far more
likely, in the time it takes you to get the code sufficiently
well optimized, debugged and compiled in C++, Mathematica could
have solved the original problem.
