I have a very simple example
#include <iostream>
int main() {
std::cout << "Hello World!" << std::endl;
return 0;
}
If I compile this with Visual Studio Compiler on Visual Studio Community 2019, then it works as expected.
However, when I change the compiler to Intel C++, installed with Intel Parallel Studio 2019, it returns an error

If I comment out the #include <iostream> and std::cout ~~, which is basically an empty program, then it compiles successfully and runs without error.

I had a similar compiling erro:

It appears to be a VS 2017 issue related to

This program meant to read number of lines then lines, and then output the number of times each word has been repeated in start of lines
for example with this input:
3
Spain Donna Elvira
England Jane Doe
Spain Donna Anna
I expect :
England 1
Spain 2
but I receive :
Spain 3
and I'm sure the the variable name is what it should be each time but something is wrong with the map.

char* are compared as pointers, not as strings. Use std::string instead.
And as P0W mentioned,scanf, printf, gets are C-style. Maps and iterators are C++-style. Don't mix them. Use std::cin, std::cout, std::getline for IO in C++.
If you map with a char* as a key, you're really mapping the with the address of the string, not the string itself as a key. Since your buffer is identically allocated on the stack every time, it will most likely end up at the same address and map to the same value, no matter the content.
Mapping from std::string, the C++ alternative to C strings, will instead automatically use the content of the string as a key.

Any STL includes in your MFC project should be included prior to the definition of DEBUG_NEW. This was a problem in the past (no longer seems to be, as I cannot reproduce it in VS 2010).
// myfile.cpp
#ifdef _DEBUG
#define new DEBUG_NEW
#endif
// This will cause the error
#include <vector>
Whereas
// myfile.cpp
// will work OK
#include <vector>
#ifdef _DEBUG
#define new DEBUG_NEW
#endif
DEBUG_NEW is a microsoft specific extension that helps to find memory leaks in debug versions of the application. It can be very useful in certain cases.
It's defined in afx.h as:
void* AFX_CDECL operator new(size_t nSize, LPCSTR lpszFileName, int nLine);
#define DEBUG_NEW new(THIS_FILE, __LINE__)`
It's helps to provide tracking of memory allocated and when a leak is detected will give you the file and line number where the allocation took place.

please help
You have to look at each complier error and fix them one at a time. We can't take a file of code and fix each error. Learning to live and even on occasion love the abusive spouse that is your complier is part of the process.
All your errors seem related to the fact that you're not passing the right template arguments to hash_multimap. Take a look at hash_multimap's documentation. The last parameter, Èqual` should be the allocator, not a function object, check out the 1st error:
c:\program files\microsoft visual studio 10.0\vc\include\hash_map(26): error C2903: 'rebind' : symbol is neither a class template nor a function template
c:\program files\microsoft visual studio 10.0\vc\include\xhash(170) : see reference to class template instantiation 'std::_Hmap_traits<_Kty,_Ty,_Tr,_Alloc,_Mfl>' being compiled
with
[
_Kty=const char *,
_Ty=int,
_Tr=std::hash,
_Alloc=Equal,
_Mfl=true
]
Edit:
If you've looked at SGI's hash_multimap documentation, you'll notice that the hash_map and hash_multimap classes are different between vendors because they are not standard. The next version of the standard comprises standard hashed containers. In the mean time, well, you'll have to write non portable code!
