need help with conditional statements

[MikeLitoris344]

im kinda new with these
to cut to the chase basically im making a game, interactive fiction to be exact.

for example:

  char choice[5];

  if (choice == "START")
     {
      cout<<"blah blah blah";
     }

but i can't seem to make it work
it's showing nothing

but this works

  char choice;
  
  if (choice == 'Y')
     {
     cout<<"blah blah blah";
     }

i don't get it

and can i ask how to sort of delay the outputs?

for example:

*knock* (1 sec. delay)
*knock* (1 sec. delay)
*knock* (1 sec. delay)
*knock* (1 sec. delay)

Neither C nor C++ supports comparison of two character arrays. If you're going to use C style strings, you have to use the strcmp library function.

Change choice to type std::string and your comparison will work as coded.

i don't know what strcmp but im studying it now thanks

can you help about my second problem too?

output should be like this:

*knock*
(1 second delay)
*knock*
(1 second delay)
*knock*

C/C++ doesn't have any built-in function to delay. That's operating system specific.

If you're on Windows, look at Sleep().
