  3. while(aWord[i])
  4. 	{
  5. 	if(isalpha(aWord[i]))printf ("character %c is alphabetic\n",aWord[i]);
  6. 	else
  7. 		delete[i]aWord;
  8.     i++;
  9.   }
Use the replace function from string:

http://www.cplusplus.com/reference/s...g/replace.html

C++ Syntax (Toggle Plain Text) 
  1. string aWord = "abcdef";
  2. aWord.replace (3, 1, "");

aWord now contains "abcef";

Edit: Or just use erase:
C++ Syntax (Toggle Plain Text) 
  1. aWord.erase (3, 1);

Has the same effect.
