The replace function allow to change a character from a string, with another. using: replace(s.begin(), s.end(), 'X', 'Y'); But it is possible to change 2 or more different characters with one? for example: In string "Tell us more about your question", I want to change all "o, i, u" with "x". So at output it will be: Tell xs abxxt yxxr qxuestixn

From another answer this should work:
void replaceAll(std::string& str, const std::string& from, const std::string& to) {
if(from.empty())
return;
size_t start_pos = 0;
while((start_pos = str.find(from, start_pos)) != std::string::npos) {
str.replace(start_pos, from.length(), to);
start_pos += to.length(); // In case 'to' contains 'from', like replacing 'x' with 'yx'
}
}

I know that answer, and I don't like it, that's why I'm asking, I don't need to replace a particular range. for example there is an answer, to change "bc" with "!!", my question is, if there it's another function like replace, to take many deiferent characters from a string and replace them with one character

@lidya_q In that case, the answer is no, there is no built in function to do what you're asking.
