Some c++ coding doubts(string stream)?

can you please explain in detail what the followinf code does?


especially what does the fgets,sizeof,and sscanf do?





char buf[50];


int option;





fgets (buf, sizeof(buf), stdin);


sscanf (buf, "%i", %26amp;option);

Some c++ coding doubts(string stream)?
fgets-: reads a string from a file


sscanf-:reads formatted input from a string


sizeof :- u have to enter the no of bits u want too use
Reply:stdin is a buffer between either the terminal or the DOS prompt. fgets is just getting what ever is in the then sscanf is putting it in option. Its a round and about way of asking for user input
