Expand your thoughts upon this:
#define INFINITY ((1 << (8*sizeof (int) - 6)) - 4)
Is expanded?
Why not
numeric_limits<float>::infinity()
or
numeric_limits<double>::infinity()
?
Use numeric_limits from <limits> header file, as
numeric_limits<float>::infinity()

I want to have a linkedlist for each key in the map in C++.
Yes, std::map<int, std::list<SomeType>> is possible in C++.
Have a look at ideone, which is useful for testing simple things such as this.

I make some calculation of float numbers in my application. In some cases I got such numbers as -1.#J and 1.#R. What does this mean?
-1.#J is either NaN or inf: What does floating point error -1.#J mean?
1.#R is underflow (exponent too small): http://www.windows-api.com/microsoft/VC-Language/31121018/1r-result-from-floating-point-arithmetic.aspx

INT32_MAX was not declared in this scope
What is the solution for this (error occurred in C++) ?
INT32_MAX is defined in <stdint.h>. You need:
#include <stdint.h>
in the offending source file.

For example, I just want it to work in the 1-10 lines, how to do it. A rookie, thanks for help.
You can use narrow-mode, and it will display only the first 10 lines, hiding the rest.

Looking for some opinions on this as it's unclear in reading the C++ 11 documentation.
Absolutely. This takes care of the rule of three for you.
