deleting a character that was written at the command promt

  Strange question. How about cout << "bla bla" Or cout << "bla bla bla\b\b\b \b\b\b".

  I know the question sounds strange but I tried to make it mor simpler . here's the real problem : I want to cout a messege and after the user has pressed a key, a part of the messege should disapear .

  I tried this cout<<" wdjfnkjvnfkjvnkvdklvnfjkvfv";

  if(_gettch()) cout<<(char)8;

  it didn't delete anything

  backspace=8;

  sorry if my English is funy ( is't not my native language)

  You're close with cout << char(8) which is the same as cout << "\b". It puts the cursor back by one position. Now you need to output a space to overwrite the last character. And another "\b" to put the cursor back again. So every cout << "\b \b" erases one character at a time.

  You can't fix that problem with a simple "\b" trick. Start reading here for Windows API functions that work with the console.

  this should be sipmle string manipulation.
  look for the space and then do what u want to do

  thanks!

  it works .

  there stil is a probleme: if the messege is to long and it has to be written on 2

  or more lines , cout<<(char)8; and cout<<"\b"; won't work!!!!!!!!!!!

  ex : cout<<"fgfdjikgnfgkjnfskgsdfjhabfvhafbvfhvbfvjadbfjvhbfdvahdbfvhfadbvfdvfdv";

  cout<<"dfdsfhgbjfdfNVVOBMNIBOBIBFJVVHBFHBhjbdfvafignbmifsoivjbnb";

  cout<<"fbnkvjnkjnvkfjvnfkvjnjvfjvkvjkvvdfdfvfdkvfdlvjfdkvjfvkjfdvfvjkafjvvjfvnfjvnfv";

  // x=lenght_of_messege;

  for(int z=x ; z>0; z-- ) cout<<"\b";

  only deletes the last line

  how can I delete all lines
