Fast way to spell checking on C++.

If you define USE_SPARSEPP before the including header file, it will much more faster than before. But also you have to sparsepp include to your project if you use USE_SPARSEPP preprocessor. Project is based on SymSpell Version 6.1 and it is much more faster than previous versions.

#include <iostream>
#define USE_SPARSEPP // optional
#include "symspell6.h"
using namespace std;
int main(int argc, const char * argv[]) {
    symspell::SymSpell symSpell;
    symSpell.CreateDictionaryEntry("united kingdom", 1);
    symSpell.CreateDictionaryEntry("united state", 2);
    char* searchTerm = (char*)"united stta";
    vector< std::unique_ptr<symspell::SuggestItem>> items;
    symSpell.Lookup(searchTerm, symspell::Verbosity::Top, items);
    return 0;
}
