string help

[michaelkrauklis]

I have a static function that accepts a string(char[]). now is there any way to copy a portion of this string dynamicly into another string? I know I could make both of the arrays the same size and then just copy over what I need, but this seems terribly wasteful. Any help would be greatly appreaciated. MYenigmaSELF

nevermind, I got it.
I'm actually tokenizing a delimited string pulled from a database. Here's the code if you're interested(it might need some tweaking, not totally finished with it):

Row* Row:rocessString(CString *string){
Row *row = new Row();

char *str_val=string->GetBuffer(0);

//cout<<str_val;

if(string->GetLength()>0){
char *pointer = str_val;
bool break_flag=false;

for(int i=0;!break_flag;i++){
if(*(pointer+i)=='&quot;'){
int z=0;
i++;
char *add=(char*)(calloc(1,8));
add[0]=NULL;
while(*(pointer+i)!='&quot;'){
z++;
add=(char*)realloc(add,z+1);
add[z-1]=*(pointer+i);
add[z]=NULL;
i++;
}
row->addNode(new CString(add));
cout<<add<<endl;
i++;
if(*(pointer+i)!=','){
break_flag=true;
}
}
else{
break_flag=true;
}
}
}

delete string;

return row;
}

fun!
thanks anyway MYenigmaSELF
