  4. Basic input/output function • Output • printf (“format”,arg1,arg2,…) • putch (char) • puts (string) • Input • scanf (“format”,&arg1,&arg2,..) • ch = getch () • gets (string);

  5. Printf (“The result is %f calculated by %f and %f \n, answer, width, height); • putch (a); // a – declared as a character • puts (s); // s – declare as a pointer of character

  6. Scanf (“Enter 3 input value %d%d%d”, &width, &length, &height); • ch = getch() ; // get one character • char *s; // declare s as a pointer of char • gets(s) ; // get string
