What is the use of getch(), putch(), getchar(), putchar()? Can't we write a program without using these in C language?
I was wondering about the use of getch(), putch(), getchar(), and putchar() functions in C language. Can we write a program without using them?
The getch(), putch(), getchar(), and putchar() functions are used for input and output operations in C language. While it is possible to write a program without using these functions, it would not be able to handle character-based input and output.
