Array Size

KarstenK

please read at first the docs about the used obejcts carefully. Often there are tiny little helper as .length or .GetLength to solve such problems. (And use the search box in top of this site a lot) :-\

What kind of array are you using? Could you please post array declaration? :)

CString store[100];,

CPallini

The size of such array is

int iSize = sizeof(store);

The number of elements of such array is

int iCount = sizeof(store)/sizeof(store[0]);

or, more concisely, 100. :)

Thanks for reply but it's not working.

CString store[100];
CString File;
and int cou=0;
store[cou]=File.

File name added at the run time.Plz help me

CPallini

What does it mean 'it's not working?' in such context? What are you trying to do? What happens instead? :)

store[cou]=File;

int iSize=sizeof(store);

AfxMessageBox(iSize);

Then i am geting Debug Assertion Fail Line number:163.

CPallini

On what line does the code assert? BTW your array is fixed-sized to 100 elements, regardless if you assign or not any of them. :)

Thank Now it is working.Your code is good.I make a mistake.SO thanks again.Ome more question how can i use dynamic array.Plz help me

CPallini

If you need an array that grows dynamically then have a look at std::vector. MFC has the CArray container but it's a crap (please don't tell this to Rajesh :rolleyes: ). very basic (and naive) vector usage sample follows:

#include <iostream>
#include <string>
#include <vector>

using namespace std;
void main()
{

vector < string > v;

v.push_back(string("hi,"));
v.push_back(string("how"));
v.push_back(string("do you do?"));
cout << "vector size = " << v.size() << endl;
for (int i=0; i<v.size(); i++)
{
cout << v[i] << " ";
}
cout << endl;
}
