Thread: need help with simple while loop (newbie)

Code:

#include <stdio.h>
int main (void)
{
int it = 0;
char ch;

printf ("type a char");
scanf ("%c", &ch);

while ( ch != 'z' )
{

++it;
printf ("type the next char");
scanf ("%c", &ch);
}
printf ("%d", it);

return 0;
}

why does the it print type next char twice??????
