Press any key to continue

Hi guys! Could you please help me? how i am going to search after the visuals? It must be looks like:

1.Visual
2.(in a certain position)Press any key to continue...
3.Enter the atomic number:
4.output

204,205,206 is not working.

i combined the function and visuals that i make. But it gives me an error after i combined and try to fixed it the message are:

Compiling COMBINE.CPP:
Warning COMBINE.CPP 202: Function should return a value

#define r rectangle
#define a outtextxy
#define b settextstyle
#define c setfillstyle
#define d floodfill

This is crazy.

You've got more than one main function in the same program. That's illegal.

i'll already fix and it's working now. Yea, i thought it works if i do that hehe. Btw, do you know sir @repeater, how to return into search bar which is in the 215? like, after i search i could back to search again or press a certain key to exit. Do you know how sir?

Repeater (3046)

You're asking "what is a loop?" http://www.cplusplus.com/doc/tutorial/control/

I recommend the while loop for your case.

while (true)
{

   // everything that should happen repeatedly here

  if ( time_to_break_out_of_loop)
  {
    break;
  }
}

daryledevs (42)

I tried the for loop, while loop and do while loop. But it doesn't work. Well, tbh, it's really hard for me to understand the looping. I tried that too the "while(true)" and it doesn't work in turbo c++. What should i do?

Repeater (3046)

Show us the code you tried.

in turbo c++. What should i do?

Not related to this question specifically, but stop using Turbo C++. It's from THIRTY years ago. It doesn't support correct C++. It makes 16 bit programs. It's a terrible choice in this world of numerous free, modern and correct C++ compilers and IDEs.

it only gives me an error message and it says "do statement must have while". I'd like to go back it from the start (visual) but i don't know how to. I can't fix it.

the concept must be :

1.visual
2.search
3. ask (13)
4.visual again
5. search again.

char p;

 do
 { 
  //visual
  

  //enter an atomic number

  // switch/case
  
   default:printf("\n invalid choice");
   printf("\n Press 'O' or 'o' to continue... or any key to exit...");
   scanf("%s",&p);
   }
   while(p=='o'||p=='O');
   }
   getch();
   return 0;
  }

Repeater (3046)

You've tried to use a do-while loop. Use a simple while loop.

while(true)
{
  // ALL THE CODE YOU WANT TO BE LOOPED HERE

  cout << "\n Press 'O' or 'o' to continue... or any key to exit...");
  char input;
  cin >> input;

  if (input == 'O'  || input == 'o')
  {
    break;
  }
}

As it is, I think this is too advanced for you. You need to go back to the basics and learn how to write loops first.

daryledevs (42)

doesn't work too it gives me an error first before crash and it says, unidentified true blah blah. it crash. Any other way?

Seems you are missing a closing brace before while.
You should really learn to format you code properly.

do
{
  //visual

  //enter an atomic number

  // switch/case
  switch(number)
  {
    case 1:
      // some code
      break;
    default:
      printf("\n invalid choice");
      printf("\n Press 'O' or 'o' to continue... or any key to exit...");
      scanf("%s", &p);
  }

}while (p == 'o' || p == 'O');

When i instert an invalid number it will appear the press... but when i input "O" it just close the window. What should i do? Btw someone suggest me to use exit function because it will return from the start but he doesn't want to teach me. Do you know how to use it?

jonnin (11436)

exit stops the program RIGHT THERE for good, program ends, destructors and such not called. terminate() does the same, except it calls the destructors and cleanups on its way out.

neither is appropriate for 'normal' behavior IMHO. If your program detects a catastrophic failure that cannot be recovered from and can cause real damage if it continues to execute, you use these types of functions. They are often abused by new programmers to quit a program but the correct way to do that is to return in main(). Return (in main) exits the program 'normally' when the program is done doing things and is the correct path to take when behaving 'normally'.

bottom line: do not use exit as a quick and easy way to end your program. Follow the normal flow of the code back home and return gracefully.

----------
what is happening with the provided code is that pressing 'o' stops the press a key code block from executing. in the while loop, it reads in. is it 'o'? yes. Break (loop stops). This puts you back to your main and ends the program without any further stopping (add another cout and cin statement pair at the end of main to see this) and the switch is similar.

you need to add the cout << "this is the end of main, press a key to exit\n" cin >> input; to your main right before return(0).

JLBorges (13770)

std::exit() ends the program after performing all clean up operations, except that destructors of objects with automatic storage duration are not called.
https://en.cppreference.com/w/cpp/utility/program/exit

std::terminate() calls the terminate handler; the default terminate handler calls std::abort() which abnormally terminates the program without performing any cleanup.
https://en.cppreference.com/w/cpp/utility/program/abort

jonnin (11436)

I should have looked them up, apologies on the misinfo.
