c-data type-format specifiers-use of %hhd

Question

i cant understand '%hhd' usage, please someone help

Answer 1

I know that's why i used short int just a indication of how many values you can use ,you can even use int
%d will refer to storage size of 2-4 bytes
%hd refers to storage size of 2 bytes
so obviously even if it isn't specified,
%hhd refers to storage size of 1 byte which is -128 to+127 as I have depicted in my example,you can do a little more search on net and you will find that %hhd stands for short short int

Answer 2

It stands for short short int ,so the value range for it is -128,+127
short int c=128;
printf("%hhd",c);
