stupid chars
Author
ok i have something like this
char* Master_Enemy_Files[] = {"Enemy_One.txt"};
but i want that whole thing to be one element i could do a multidemntional array but thats a PAIN im using c++ and i just want a way to make a const char* {"blabla"}; to be one SINGE entity is there any way to do this
You mean like this?
std::string Master_Enemy_Files[10];Master_Enemy_Files[0] = "Enemy_One.txt";Master_Enemy_Files[1] = "Enemy_Two.txt";Master_Enemy_Files[2] = "Enemy_Three.txt";...

yes thats exactly what i mean but unless you have a really good way to transfer those strings to chars i cant use em

just use the c_str() method in the string class to convert to chars.

its not that i dont like it in fact i love it but when inputting file names the function takes only chars
Hi,
I think it's because people usually get taught char arrays first, so they stick with what they've originally learned. Some people feel more comfortable using already defined data-types instead of user-defined classes.
I have seen some people post threads around the internet talking about how inefficient the string class is because it wastes memory (like when you concatenate). But when you look at the big picture the difference is negligible. It would obviously depend on it's application though.
Just my 2 cents,

what files must i include in order to use the c_str method because as of right now it says it dont exist here are the files i have so far
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <vector>
#include <stdlib.h> // Include this to use system()
#include <iostream> // Include our standard header
#include <string> // Include this to use strings
#include <fstream>
#include <libiberty.h>
#include "Ship.h"
#include "Enemy.h"
#include "Level.h"
#include "SDL.h"
#include "Input.h"
using namespace std;
or is this a member function like str1.c_str(char1)?
never mind figured it out its the later
#include <stdio.h>
#include <stdlib.h>

ok im having a little trouble here shouldnt this work?
Enemy_List[One->Enemy_Vector->ID].c_str(Enemy_List_C);
string Enemy_List[]= "Enemy_1.bmp";
char* Enemy_List_C= "";
i get this error
