Is conio deprecated?

Header file. conio. h header file isn’t used anymore. It was used in old Turbo C compiler which are 16-bit and all your programs run virtually on 8086 microprocessor.

What can I use instead of getch in 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 does PUTC do in C?

The putc() function converts c to unsigned char and then writes c to the output stream at the current position. The putchar() is equivalent to putc( c , stdout) . The putc() function can be defined as a macro so the argument can be evaluated multiple times.

What happens if I remove getch() statement from the example code?

Hence the user can view the output on the console until he presses any key on the keyboard. Now if we remove getch () statement from the example code, the program is compiled successfully. But the console turns off as soon as the program is executed completely which is, in general, a matter of milliseconds.
