How to remove certain characters from a string in C++?

Question

For example I have a user input a phone number.

cout << "Enter phone number: "; INPUT: (555) 555-5555 cin >> phone; 

I want to remove the "(", ")", and "-" characters from the string. I've looked at the string remove, find and replace functions however I only see that they operate based on position.

Is there a string function that I can use to pass a character, "(" for example, and have it remove all instances within a string?

Answer 1

   string str("(555) 555-5555");     char chars[] = "()-";     for (unsigned int i = 0; i < strlen(chars); ++i)    {       // you need include <algorithm> to use general algorithms like std::remove()       str.erase (std::remove(str.begin(), str.end(), chars[i]), str.end());    }     // output: 555 5555555    cout << str << endl; 

To use as function:

void removeCharsFromString( string &str, char* charsToRemove ) {    for ( unsigned int i = 0; i < strlen(charsToRemove); ++i ) {       str.erase( remove(str.begin(), str.end(), charsToRemove[i]), str.end() );    } } //example of usage: removeCharsFromString( str, "()-" );
