String character removal

[joewbarber]

Hi,

I know how to remove certain characters from a string by using something like this

  string str ("Hello world!");
  erase (0, 6);

That's great if I want to do that manually, but say if someone entered a string, how would I automatically remove every other character they entered? Sorry if this is a poor explanation, but I hope someone can help me.

Off the top of my head.

Use a for loop get the length of the string and then erase.

Let me know if you have any questions.

string str;
getline(cin, str);

int i = 0;
while( ++i < str.length() )
    str.erase( i, 1 );
