He said "because of getch ". But when I run the program it is totally working. What I have tried: I haven't tried anything yet because my friend is kinda far away. We only see during school days and right now we are on a holiday break.

We can't answer that; or even begin to - we can't see the code, we can't see your screen, we can't see your friend's screen, we can't access your HDD, and we can't read either of your minds! You and your friend need to learn how to report a problem, and how to ask a question: at the moment, you have broken down in the middle of nowhere, called the garage us and said "It don't work.

My friend says it the bit which goes round" and put the phone down. How long do you think it will be until the garage arrives with the right parts to fix your car? Try reading here: Tips for asking technical questions that result in fast, useful solutions Opensource. What symptoms did it show?

Do you allow the user to make …. I'm sure it works just fine on your compiler, but because it's non-standard, that means it's not guaranteed to work on …. I recommend you resist that temptation next time.

Posers should know their limits. It's a library function. If you want to split hairs with terminology, it's a library extension. If you're rude to me, don't expect me to be nice to you. Not only am I quite familiar with the rules, I'm in the unique position …. For what purpose were you intending to use getch? The most common by far is keeping a console window from closing when you run the program from a Windows IDE:.

That's not a recommended solution, and most experienced programmers will recommend that you use cin. Okay, I have to say that i often use getch not just to halt the console window. I used getch along with kbhit [to get the key if pressed any]--very important use of getch. And there are times when I have given the user to choose from a number of options menu items and used getch to get the choice. I know the latter can be done with any input functions but getch makes it simpler-- scanfcin and cin.

On the otherhand it's very common for scanfcin and cin. I hope some one here will suggest how to work that out without using getchsince according to "Narue" its a compiler extension and not a C function. Now we dont to code using something that is not part of the language. Do you allow the user to make a typing mistake?

Then handle the backspace. Then you can't have immediate response because you need an "enter" for a 'final' answer. Then you're back where you started with the standard way. The reason it may 'work well' might be because other issues have been overlooked.

Using the getch() function in C/C++

It seems a more reasonable approach is to use standard functions that have already taken such issues into account and move forward.

Yet this opinion is revisited thousands of times every year by programmers. Their first goal seems to be clearing the screen.Join Stack Overflow to learn, share knowledge, and build your career. Connect and share knowledge within a single location that is structured and easy to search. I'm making a small C program that asks for a key and executes some code in a switch statement.

Some background: conio. It was originally just a wrapper around MS-DOS functions, so you didn't have to write your own assembly creating an int 21h to call them. The exact API of conio. I assume you're using a compiler targeting Windows, these typically still provide some variation of conio. But as you can see, there's no guarantee what's really available and works as you would expect. Nowadays, you'd even have to ask what is a screen?

The content of your console window? But what if your controlling terminal is e. And even different console window implementations will differ in features and how you control them. For actually controlling the "screen", Windows provides the Console APIyou could use that directly, but then your program is "hard-wired" to Windows only.

Windows starting with Windows 10 has optional support for them as well. But there's a wide variety of terminals understanding different codes and different subsets of themso using them directly isn't a good idea either. Most notably, ncurses is available for many systems, even including Windows, but for Windows, you also have pdcurses.

There's even an extended pdcurses for Windows that implements its own console window, so you can use features the native Windows console doesn't have.

Of course, you won't need this for just "clearing the screen" and reading some input from the keyboard. Here's a tiny example program:.

As you can imagine, I am constantly writing new articles on What Acca. Making a selection is really simple, thanks to the super user-friendly interface that bet365 are currently rocking. You can use the left hand side panel to select the sport you want to bet on, before then being able to choose from a breakdown of leagues, tournaments, competitions or just stand alone matches. This will vary from sport to sport, but just taking football (soccer) as our example, we can see that there is a plethora of options to choose from.

After then going into the competition you are looking for, a list of matches will be on offer with the results market initially shown. Next to each selection you will be able to choose additional markets for you to customise even further.

Your bet slip will always be apparent on the far right hand side of the screen. To place a selection into your bet slip you simply click the yellow odds taken from the market you have selected.

Often you will find that when faced with choosing selections, especially for football markets, you will be greeted with three selection boxes listed as 1, X and 2.
