int main(){ char a[10]; char b; printf("enter a\n"); scanf("%s",a); printf("enter b\n"); scanf("%c",&b); printf("%s %c",a,b); return 0; }

After I enter the first line of input which is stored in a, the program exits and doesn't let me take an input for b unless I clear the input buffer by using fflush(stidn). This works fine however if b were an array and I read one string after another without flushing the input buffer. Why the difference between a string input and a character input?

scanf(" %c",&b);

Note the space there.

#

That space "eats" all whitespace that remains in the buffer ahead of your input.
So you don't need to flush the buffers.

short steeple ```c scanf(" %c",&b); ``` Note the space there.

Or you can use getchar(); as well following scanf().
