Clrscr() and Getch() in C++
May 31, 2016 Hari ini saya akan berbagi pengetahuan tentang fungsi sungsi gets, getchar, getch dan juga getche. Untuk mempersingkat waktu langsung saja berikut ini sedikit penjelasannya. Fungsi gets Fungsi ini memiliki kegunaan sebagai input data pada program, namun fungsi ini hanya dapat melakukan input data yang berbasis karakter sehingga data. C getchar The getchar function in C reads the next character from stdin. Most of the program is ending with getch, and so we think that getch is used to display the output.but it is wrong.It is used to get a single character from the console. Just see the behaviors of various single character input functions in c. Getchar, getche, getch.
clrscr() and getch() both are predefined function in 'conio.h' (console input output header file).
- A simple typewriter. Every sentence is echoed once ENTER has been pressed until a dot (.) is included in the text. See also getc Get character from stream (function ) putchar.
- Getche This is a nonstandard function that gets a character from the keyboard, echoes to screen. Use getchar if you want it to work on all compilers. Use getch or getche on a system that supports it when you want keyboard input without pressing Enter. And note that the return value of all three is int! You need this to properly check for EOF.
Clrscr()
It is a predefined function in 'conio.h' (console input output header file) used to clear the console screen.It is a predefined function, by using this function we can clear the data from console (Monitor). Using of clrscr() is always optional but it should be place after variable or function declaration only.
Output
Getch()
It is a predefined function in 'conio.h' (console input output header file) will tell to the console wait for some time until a key is hit given after running of program.
By using this function we can read a character directly from the keyboard. Generally getch() are placing at end of the program after printing the output on screen. Traktor pro for mac download.
