How to give a file path instead of file name c++?

This code part is from a simple md5 hash generator.But here i can only give a file name to generate the md5.

LPCWSTR NameOfTheFile = L"Test.txt"; //Name of the file that user is scanning

But i want to give a file path here instead of the file name..Is there any way to do that.?

#include <iostream>
#include <windows.h> 
#include <fstream>
#include <string>

#define BUFSIZE 1024
#define MD5LEN  16


using namespace std;


DWORD main()
{

    MaximizeOutputWindow();

    DWORD cryptStatus = 0;

    BOOL hashResult = FALSE;

    BYTE fileSizeToHash[BUFSIZE];

    HCRYPTPROV cryptProv = 0;

    HCRYPTHASH hash = 0;

    HANDLE file = 0;

    DWORD hashNumbCount = 0;

    DWORD hashRead = 0;

    BYTE getHashValue[MD5LEN];

    CHAR numberConvert[] = "0123456789abcdef"; //hex decimal conversion

    LPCWSTR NameOfTheFile = L"Test.txt"; //Name of the file that user is scanning


    // Logic to check usage goes here.
    file = CreateFile(NameOfTheFile, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_FLAG_SEQUENTIAL_SCAN, NULL);
