(which includes the standard C++ libraries). Ubuntu provides the standard Gnu Compiler Collection in the repositories.

How do I know if gcc is installed on Ubuntu? * Read 1 character with echo getche() function definition.What is the difference between sudo apt and sudo apt-get? * Read 1 character without echo getch() function definition.

* Read 1 character - echo defines echo mode */ char getch_( int echo) * Restore old terminal i/o settings */ void resetTermios( void) Tcsetattr( 0, TCSANOW, & new) //apply terminal io settings Tcgetattr( 0, &old) //grab old terminal i/o settings new = old //make new settings same as old settings new.c_lflag &= ~ICANON //disable buffered i/o new.c_lflag &= echo ? ECHO : ~ECHO //set echo mode * Initialize new terminal i/o settings */ void initTermios( int echo) getche() is declared in conio.h header file.Ĭonsider the example: #include #include static struct termios old, new it displays the input character & it does not require key after input. Getche() function is used to get (read) single character from standard input device (keyboard) with echoing i.e. getch() is declared in conio.h header file. it does not display the input character & it does not require key after input. Getch() function is used to get (read) single character from standard input device (keyboard) without echoing i.e. clrscr() function definition void clrscr( void)Ĭonsider the example: #include // clrscr() function definition void clrscr( void) We can implement clrscr() by using clear command of the linux terminal, It is used to Clear Output Screen. Printf( 'Hello World!!!') //print message return 0 gotoxy() function definition void gotoxy( int x, int y)Ĭonsider the example: #include // gotoxy() function definition void gotoxy( int x, int y) Gotoxy() move the cursor at specified location in the output screen.

In TurboC compiler you can use that functions by including conio.h header file, but in Linux library these function are not available, so we are providing the function definitions for GCC linux just use them into your program and call where they needed. In this section you will learn how gotoxy(), getche(), getch() and clrscr() function can be used in GCC Linux. Gotoxy(), clrscr(), getche() and getch() in GCC Linux:
