Hi, I am using gcc on Debian GNU/Linux, here is a program I wrote, #include<stdio.h> int main() { int d; char a; scanf("%d",&d); fflush(stdin); scanf("%c",&a); printf("%d%c",d,a); return 0; } But, fflush(stdin) was not as it should, it was not clearing buffer, so I was not able to read the character input from the user. So, is there any way to flush the buffer and read the character input from the user? Please help me out. Regards, cnu
