What does %d mean in scanf?
a decimal integer

How do I read a character in scanf?

How do I add a character to a scanf file?
Input individual characters using scanf() in C scanf (“%c%c%c”, &x, &y, &z); Now, if the input is “a b c”, then ‘a’ will be assigned to variable x, SPACE will be assigned to variable y and ‘b’ will be assigned to variable z. Thus, scanf() reads the characters as well as space, tab and new line character.
