What can I use instead of getch?

What can I use instead of getch?

There isn’t a direct replacement in standard C++. For getch(), int ch = std::cin. get(); is probably the closest equivalent — but bear in mind that this will read from buffered standard input, whereas I think the conio. h getch does an unbuffered read.

How do you use getch without conio H?

There are many alternatives for this :

1. Use clrscr() included in conio. h.
2. If working with iostream is compulsory then go for.
3. You can even write cin>>var; and ask user to press Enter.
4. If you’re a Windows user system(“pause”) is a command you can try.

Is Getch necessary?

In Turbo C++ it is necessary for to define getch(); so as to be able to see the output screen If it is not present then the output will be produced within few second but the output screen doesn’t pauses…. While coding C program in Dev Cpp getch(); is NOT needed…

What is the function of getch ()?

We use a getch() function in a C/ C++ program to hold the output screen for some time until the user passes a key from the keyboard to exit the console screen. Using getch() function, we can hide the input character provided by the users in the ATM PIN, password, etc. Syntax: int getch(void);

What is the C++ equivalent of the conio get() function?

The conio.h functions are compiler extensions to the language, not part of C or C++. There isn’t a direct replacement in standard C++. For getch(), int ch = std::cin.get(); is probably the closest equivalent — but bear in mind that this will read from buffered standard input, whereas I think the conio.h getch does an unbuffered read.

What is the C++ equivalent of getch()?

What is the replacement for getch() in Java?

Enjoy productive Java with IntelliJ IDEA. Discover instant and clever code completion, on-the-fly code analysis, and reliable refactoring tools. Looks like we don’t have any exact replacement for getch (). None of the similar fxns can handle both the requirements. getche () is the closest thing but it is again under conio.h and hence useless.

Is there a portable way to make a getch() function?

There’s no portable way to do this. The closest you can come is some sort of third party library that handles the portability issues for you. Curses probably comes the closest to doing that. Otherwise you have to write your own clear(), kbhit(), and getch() functions, with separate versions of each for each operating system.
