CArray or user defined array??

do you want the size of the array in bytes, or the number of elements in the array? if you want the size in bytes, use the sizeof() like so;
int size_in_bytes;
int theArray[20];
size_in_bytes = sizeof(theArray);Hi, Dont use user defined array in this case. You better use CStringArray. Then you no need to calculate the size of the array. This class is having a member function int GetSize() to get the size of the array.

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

The
sizeof such array isint iSize = sizeof(store);
The
number of elementsof such array isint iCount = sizeof(store)/sizeof(store[0]);
or, more concisely,
100. :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

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
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.
On what line does the code assert? BTW your array is fixed-sized to
100elements, regardless if you assign or not any of them. :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

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
If you need an array that grows dynamically then have a look at
std::vector.MFChas theCArraycontainer 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;
}:)

Thanks for reply but it's not working i have a CString store[100];,CString File; and int cou=0;. And i use store[cou]=File. And i want to get Size of store[cou].Plz help me
store[cou].GetLength()
