substract character from string?

Is there a function to substract certain charakters from a string?

My string contains masses of ';' between various characters that I want to process.

Thanx.

So you want everything in the string besides the ';'?
Sounds like a job for strtok. Google found me this: http://www.opengroup.org/onlinepubs/...sh/strtok.html

Here's a program :

Code:

---

#include <string>
#include <iostream>
using std::string;

string strremove(const string& str, char rm)
{
  string strnew;
  for (string::size_type p = 0;p < str.length(); ++p)
    if (str[p] != rm)
      strnew += str[p];
  return strnew;
}

int main()
{
  string foo = ";;;;sang-;;;drax;;";
  std::cout << strremove(foo,';');
}

---

I already tried strtok. It had Problems returning tokens like ' - + / '. Any Idea, why?

Code:

---

lkv_Pointer = strtok (lkv_String, ";");
while (lkv_Pointer != NULL)
{
        cout << lkv_Pointer << endl;
        lkv_Pointer = strtok (NULL, ";");
}

---

My lkv_String looks something like this:

Code:

---

;;;;;;;;;;;;-20;;;;;;+60;;;;;;;;-30;;;;;;;;

Sorry! Ignore my last post - found mistake.
Thanks for all replies!

you're using string classes, right? if you search google i think there's a list of member functions for that, some which may help you here.
