Reading a character in C

readchar.c

char firstCh, secondCh;

printf("Enter first character: ");
scanf(" %c", &firstCh); // Note: a space before %c
printf("Enter second character: ");
scanf(" %c", &secondCh);

// The following WON'T work as the newline entered as part of the first scanf would be consumed by the next scanf call:
printf("Enter first character: ");
scanf("%c", &firstCh); // Will not work correctly!
printf("Enter second character: ");
scanf("%c", &secondCh);
