By setting the file attributes to type "HIDDEN"...

Thanks in advance

memcpy is used to copy a specified number of bytes to a destination and not for comparison and strcpy is used to copy a string to another location ie source to destination.

sorry... i wrongly mentioned mmcpy and strcpy those should be mmcmp and strcmp...........
can you please re answer my question

strcmp- compare data between two strings. you don't have the advantage of specifying the number of bytes that you want to compare. It's always the complete string that is compared.

It's memcmp by the way
memcmp provides you the flexibility of comparing bytes in the string by mentioning the count

Thanks alot ....
one more question
which one should be prefered for
1.Two constant string
2.One const. and one veriable string..
is it strcmp and memcmp respectively for above ..

It depends, whether you want to compare the complete strings or only a few bytes. You should be better off using strcmp in either of the cases if you compare the complete strings

I'm currently using 2-dimensional dynamic array as a function parameter to store value of double. My problem is my program sometimes having a runtime error. I've try a m=3200 x n=58 array size, it only run for a wait before aborting the program. When I reduced the size of the array it works. Here is my declaration of the array:
double* precomp=new double[(_CANVAS_WIDTH /_TILE_WIDTH)*(_CANVAS_HEIGHT /_TILE_HEIGHT)*_TILE_COUNT];
int i,j;
for( i = 0; i < (_CANVAS_WIDTH /_TILE_WIDTH) * (_CANVAS_HEIGHT /_TILE_HEIGHT); i++)
for(j=0; j< _TILE_COUNT;j++)
*(precomp + i* _TILE_COUNT+j) = 0.0;
calculate(TheList, Target, precomp);Here is the function implementation :
void calculate(double* param1, double TargetValue, double* precomp)
{
double _tile;
for (unsigned int y=0; y<list_index;> {
for (unsigned int j=0; j<num_of_tiles;> {
_tile = param1[j];
cout<<"Pre-calculating value for location"<<y<<":tile "<<j<<endl;
*(precomp_fitness + i*num_of_tiles + j) = abs(TargetValue - _tile);
}
}
}
If anyone could help me understand what was happening, it is very appreciated. Thanks.

You probably cannot get meaningful help because:
- Your scenario + code don't give enough info (you state
m=3200 x n=58) but in your code there are just other constants (such as _CANVAS_WIDTH), that are, for us, of undefined value. - Your code is not properly formatted, see wrong syntax in
for iterations inside calculate function. - Your code gives incomplete info (for instance, how are defined the parameters of the
calculate function? - You don't provide any debug info (for instance what is the offending line?). You are strongly advised using the debugger, that is the king of the programmer's tools
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

These are the contents of the csv file

Where would you like to see the contents ? In a edit control, list control, ... ?
Anyway, you have to split the problem in two parts: first is to read the data from the file. For this you can look at std::ifstream. And second part is to display your data. The way you do it is totally dependent on how you want to display it.
So please provide more information (as somebody already suggested).
