We know range of signed char -128 to 127. But in the given code answer is 1200. So, here we should get an overflow.Integer Promotion occurs which prevents to cause it overflow. How ... d = (a * b) / c; printf ("%d ", d); return 0; }

Since in a machine we always store numbers in binary then why can't we directly print the binary number itself using any inbuilt function, why do we have to write a separate code for it every time?
