c++调用lua:

#include "stdafx.h"

extern "C"{
#include "lua.h"
#include "lualib.h"
#include "lauxlib.h" 
}

#pragma comment(lib, "lua5.1.lib") 

///lua 解释器指针
lua_State* L = nullptr;

int luaAdd(int x, int y)
{
    lua_getglobal(L, "add");
    int nTop = lua_gettop(L);

    lua_pushnumber(L, x);
    nTop = lua_gettop(L);

    lua_pushnumber(L, y);
    nTop = lua_gettop(L);

    lua_call(L, 2, 1);

    nTop = lua_gettop(L);

    int sum = (int)lua_tonumber(L, -1);
    nTop = lua_gettop(L);

    lua_pop(L, 1);

    return sum;
}

int _tmain(int argc, _TCHAR* argv[])
{
    L = lua_open();

    luaopen_base(L);
    luaL_openlibs(L);

    luaL_dofile(L, "add.lua");

    int sum = luaAdd(10, 15);
    printf("%d", sum);

    lua_close(L);


    system("pause");
    return 0;
}
