changing a part of a string
-
hello everybody! I'm having trouble in changing a certain string. if I have have that string: strNum = 1234&567; the thing is that I want to change the "&" sign to the "and" so my string will be 1234and567. can anyone help me with that somehow??? :confused: Thanks!
Does CString have a Replace function ? I don't think that std::string does. Either way, either you or a wrapper needs to allocate new memory and construct a new string ( char * ), because you want to replace one character with 3.

you should tokenize the string with a delimiter of your choice, then append the tokens back into your string. // code for tokenizing, taken from http://oopweb.com/CPP/Documents/CPPHOWTO/Volume/C++Programming-HOWTO-7.html[^] void Tokenize(const string& str, vector& tokens, const string& delimiters = " ") { // Skip delimiters at beginning. string::size_type lastPos = str.find_first_not_of(delimiters, 0); // Find first "non-delimiter". string::size_type pos = str.find_first_of(delimiters, lastPos); while (string::npos != pos || string::npos != lastPos) { // Found a token, add it to the vector. tokens.push_back(str.substr(lastPos, pos - lastPos)); // Skip delimiters. Note the "not_of" lastPos = str.find_first_not_of(delimiters, pos); // Find next "non-delimiter" pos = str.find_first_of(delimiters, lastPos); } }

Thanks! :-) understood!

If this String is Object of CString then you simply use this Function CString strNum = "1234&567";
strNum.Replace("&","and");

visit me at http://www.thisisalok.tk "I Think Believe this Will Help"yeah I know, but I was looking for string, not CString. but, I don't quite understand the difference between the two. I know that CString is microsoft's string class, and it has more functionality, but what are the disadvantages of CString comparing to string?

Cstring is MFC dependent class whereas STL string as no such dependency!

visit me at http://www.thisisalok.tk "I Think Believe this Will Help"i've checked the string class, and it also contains a replace member function, so essentially you can do the same thing that alok said for the CString class. anyway here's more definitions for the string class: http://www.cppreference.com/cppstring/[^]
