WebApr 15, 2024 · To handle the negative integer, we use the abs function to obtain the absolute value of num. We then use integer division to obtain the first two digits of num by dividing the absolute value of num by 100. We store the result in an integer variable first_two_digits. WebApr 22, 2024 · Negative lowest number that can be stored is - (2 (k-1) -1)and positive largest number that can be stored is (2 (k-1) -1) .
