Removing parts of a string...

How do i remove a character from a string by using it's position?

In my encryption algorithm it has to pad the data if it is not a factor of the 128-bit block size. I want to remove the padding in the decryption but it will not let me do this:

Code:

---

...
string.at(i) = "";
...

---

I know there's an .erase() function but i dont know if that's the way to do it.


Thanks for the help!

I believe erase takes an iterator. If so, and you only have a position, just add the position to the begin() iterator:

Code:

---

str.erase(str.begin() + i);

---

There might be better options if you are erasing multiple characters or erasing from the end of the string.

Dankeschon!

Works grrrreaaaaaaattttttt!
