Output of the Program
What will be the output of the program if value 25 given to scanf()? The scanf function returns the number of input is given. printf("%dn", scanf("%d", &i)); The scanf function returns the value 1(one). Therefore, the output of the program is ‘1’.
Fflush System Call

Use of fpurge()
Rispetto a questo,, how do you use fpurge()? The function fpurge() clears the buffers of the given stream. For output streams this discards any unwritten output.

Buffer Size in C
Riguardo a questo,, what is a buffer size in c? Using C code, user can access each and every bit of memory on computer system. So when you declare a buffer of 10 bytes(char buffer[10]), OS will set aside that much bytes to be used by your program only. You can use up to 10 bytes in whatever manner you want.
