STL Container Size Limit Report

[kryton9]

I wrote this little test program to find the size limits of some of the Standard Template Library Containers. I would like to see what differences, if any, and which situations machine to machine, OS to OS or both.
It is a console app. You might need to scroll up to see the whole output. It will give your results first and then print my results for reference.

The code listing is just for reference. The attachment has the executable console app.


#include <iostream>
#include <stdlib.h>
#include <vector>
#include <list>
#include <map>

using namespace std;

int kvs = 1073741823;
int kvi = 1073741823;
int kls = 357913941;
int kli = 357913941;
int km = 178956970;

int main()
{
vector<string> vs;
vector<int> vi;

list<string> ls;
list<int> li;

map<int,string> m;

cout << endl << " Container Limits" << endl << endl ;

cout << " Your Results: "<< endl << endl;
cout << " Vector of strings: "<< vs.max_size() << endl;
cout << " Vector of integers: "<< vi.max_size() << endl << endl;

cout << " List of strings: "<< ls.max_size() << endl;
cout << " List of integers: "<< li.max_size() << endl << endl;

cout << "Map of ints and strings: "<< m.max_size() << endl << endl;
cout << "==================================================" << endl;
cout << " Kent's Results: "<< endl << endl;
cout << " Vector of strings: "<< kvs << endl;
cout << " Vector of integers: "<< kvi << endl << endl;

cout << " List of strings: "<< kls << endl;
cout << " List of integers: "<< kli << endl << endl;

cout << "Map of ints and strings: "<< km << endl << endl;
system("pause");
return 0;
}

Kent,


I am a novice c++ programmer so I use the latest Bcx. No {}; needed


Using MinGWTDM compiler on Win7 64.
Compiled as 32bit and 64bit app
32bit matches yours. Not sure on the 64bit results

Thanks James. I am sorry I forgot to mention the attachment had an executable. I just listed the code, for reference, as to what was in the executable.
You pointed out a major flaw in my test, not testing for 32 bit and 64 bit. Thanks for both listings. At least I know now that it can change.
