Coverting varibles

Oct 28th, 2005

I was wondering if there's a way to convert a CString or a char *x[10] to a int? I know I can convert int to CString, but can it go the other way?
Thanx,
Atrus

Sure, why not?

Old computers are getting to be a lost art. Here at Uncreative Labs, we still enjoy using the old computers. Sometimes we want to see how far a particular system can go, other times we use a stock system to remind ourselves of what we once had.

for CString (I assume you mean Microsoft MFC CString class)

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
// convert from CString to int just requires typcasting the CString
CString str = "123";
int n = atoi((LPCTSTR)str);
 
// convert from int to CString
str.Format("%d", n);
// convert from CString to int just requires typcasting the CString
CString str = "123";
int n = atoi((LPCTSTR)str);

// convert from int to CString
str.Format("%d", n);

ok so would the following statement work then?

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
char *str[5];
str[0] = "123";
int n = atoi((LPCTSTR)str[0]);
char *str[5];
str[0] = "123";
int n = atoi((LPCTSTR)str[0]);

and yes I meant MFC CStrings... Sorry I didn't mentionthat

you don't need to typecast character arrays -- that typecast is to convert a CString object to const char*.

char *str[5];
str[0] = "123";
int n = atoi(str[0]);
char *str[5];
str[0] = "123";
int n = atoi(str[0]);
