Input-output function –In C programming, an input-output function is one that either takes user input or sends data to the user. These capabilities allow programmers to interface with users as well as receive or provide information. Printf(), scanf(), getchar(), and putchar() are examples...
The putchar function which in analogus to getchar function can be used for writing characters one at a time to the output terminal. The general form is putchar (variable name); Where variable is a valid C type variable that has already been declared Ex: Putchar ( ); Displays the value...
we might encapsulate it into a function we could call, perhaps called “flushline” or something. Or, recognizing that “read characters up to a newline” is precisely what the Standard functionsgetsandfgetsalready do, we might simply interpose calls togetsorfgets, reading into ...

You can write a function that does map, then join. This function is called bind, or flatMap, or (>>=), or (=<<). This is normally how a monad instance is given in Haskell. A monad has to satisfy certain laws, namely that join must be associative. This means that if you have ...
