fflush() is not working in Linux

Question

I used the fflush() in Linux GCC but it did not work. Are there any alternatives for that function? Here is my code:

#include
void main()
{
           


        

Answer 1

fflush() doesn't do much for input streams but since scanf() never returns this doesn't matter. scanf() blocks because the terminal window doesn't send anything to the C program until you press Enter

You have two options:

1. Type 10 Enter
2. Put the terminal into raw mode.

The second option has many drawbacls like you will lose editing capabilities, so I suggest to read the input line by line.
