Thread: Reading Blank Char

Code:

#include <stdio.h>
#include <conio.h>

main()
{
      char a,b;
      printf ("Enter the first character: ");
      scanf ("%c",&a);
      printf ("Enter the second character: ");
      scanf ("%c",&b);
      printf ("\n");
      if (a>b)
         printf ("a is larger than b");
      getch();
}

Hey,
{Java-programmer, new to C, read tutorials, Googled, FAQed)

Problem: Run the code, and the software automatically assigns blank character to b {i think ASCII = 10}.
It doesn't even give me the chance to insert a value to b!
Why?
Thank for helping.

You can also add a space in front of the %c for the second scanf to tell it to ignore leading whitespace.

Code:

printf ("Enter the second character: ");
scanf (" %c",&b);
