Thread: Using sputbackc () in C++

I started learning C++ language and want to create project in it. I know functions and use of them in C++. But, I didn’t have any idea about sputbackc () function. So please provide me some information about this function. Any help will be appreciated.

The sputbackc () function utilized to put character back. The get pointer shifted back to point that to character right earlier than its place when last character got, d, that becomes available again as character that read at that position by next input operation. This function is member function of streambuf class.

This function puts char_type in particular stream and returns character or failure. General form of sputbackc () function is shown below:

Code:

int sputbackc ( char d );
