Question

my question is a little bit strange, but how is it possible to read some string from keyboard char by char without using scanf() and getchar() only by using operator<<, for example I want to change every letter a which I read by * thanks in advance

Answer 1

char c;
std::string output;


while(std::cin >> c)
{
   if(c == 'a')
      c = '*';

   output += c;

}
