What is the use of #include conio.h in c programming. The C programming language’s conio.h header file contains routines for console input/output. clrscr, getch, getche, kbhit, and other functions are among the most widely utilised. They can be used to clear the screen, change the text and background colour, reposition text, check if a key is hit, and execute other operations.
Clearing the console screen is a predefined function in the “conio. h” (console input output header file). It is a predefined function that can be used to clear the data from the console. To clear the console screen, use clrscr(). To use this function, we must include the #includeconio. h> header file. The clrscr() function is used to clean the console window in the C programming language.
The delline function deletes the line on which the cursor is now located and shifts any lines below it one line up. The C programming language’s conio.h header file contains routines for console input/output.
In a C application, the getch function requests the user to press a character. It isn’t visible on the screen. It is declared in the header file “conio.h.” The function isn’t included in the C standard library. This application only exits when you press a character when you execute it.
The getche function asks the user to press a character, which is then displayed on the screen. The getche() function in the C programming language waits for any character input from the keyboard before echoing the character to the output screen. The description and syntax for the aforesaid file handling function may be found below.
The gotoxy function moves the cursor to a specific location on the screen, allowing us to alter cursor position. The gotoxy() function in the C language is used to move the control cursor to a certain location on the console screen. The gotoxy() function can take two inputs, one for the X coordinate and the other for the Y coordinate.
The C function kbhit is used to determine whether or not a key has been pushed. You must include the header file “conio.h” in order to utilize it in a program. If a key is pushed, it returns a value that is not zero; otherwise, it returns zero.
In the C programming language, the wherex() function returns the x coordinate of the cursor in the current output screen. And there’s the wherey() function, which returns the cursor’s y coordinate in the current output screen.
The wherey() function returns the cursor’s y coordinate in the current output screen. Both functions are defined in the header file conio.h. The wherey() function returns the cursor’s y coordinate in the current output screen. Both functions are defined in the header file conio.h.
In-text mode, the function text background is used to modify the current background colour. The colour is a variable with an integer value. For example, 0 denotes BLACK, 1 denotes BLUE, 2 denotes GREEN, and so on. Instead of using integer, you can use write appropriate colour.
