C API example for stack operations in Lua

This is an example of LUA programming, a simple record.

#include <stdio.h> #include <lua5.2/lua.h> #include <lua5.2/lauxlib.h>static void Stackdump (Lua_    State *l) {int i;    int top = lua_gettop (L);        for (i = 1; I <= top; i++) {int t = Lua_type (L, i);                Switch (t) {case lua_tstring:printf ("'%s '", lua_tostring (L, i));            Break Case lua_tboolean:printf (Lua_toboolean (L, i)?                "True": "false");            Break                Case lua_tnumber:printf ("%g", Lua_tonumber (L, i));            Break                default:printf ("%s", Lua_typename (L, t));        Break    } printf (""); } printf ("\ n");}    int main (void) {Lua_state *l = Lual_newstate ();    Lua_pushboolean (L, 1);    Lua_pushnumber (L, 10);    Lua_pushnil (L);    Lua_pushstring (L, "Vonzhou");    Stackdump (L);    Dump the Stack lua_pushvalue (L,-4);//Push the value of the index to the stack stackdump (l); Lua_replace (L, 3);  Pop a value and replace the index ' s stackdump (L);   Lua_settop (L, 6);    Set the top index, fill ' nil ' stackdump (L);   Lua_remove (L,-3);    Stackdump (L);    Lua_settop (L,-5);    Stackdump (L);    Lua_close (L); return 0;}
