2’s Complement – C Program

PHLeave a comment

We can obtain 2’s complement in atleast two ways through a C program. If n is a number then -n will give the result. The next approach is to first flip all the bits (1’s complement) and then add 1. The bits can be flipped using ~ operator. The program below demonstrates both the approaches.

The day stands ahead. That day, where it would be difficult to judge on who deceived us. Was it a machine or a man? Was it a machine who said it was a man and deceived us OR was it a man who behaved like a machine and deceived us? The line is thin. The… Continue reading That Day of Machines

Check if Number is Odd Using Bitwise – C

PH1 Comment

An odd number always has the LSB set to 1. If we AND the given number with 1, the even number will always turn out to be zero. We can using this to check if the number is odd or even. Examples: 1) n = 4 100     (4) 001     (1) ———– AND 000… Continue reading Check if Number is Odd Using Bitwise – C

Case Conversion using Bitwise – C

PH1 Comment

We generally use the functions strlwr() and strupr() available under string.h to toggle between the cases. This can also be achieved using bitwise operations. Before that, lets understand the ASCII table. ASCII of A is 65 (1000001) ASCII of a is 97 (1100001) Similarly, ASCII of Z is 97   (1011010) ASCII of z is 122 (1111010)… Continue reading Case Conversion using Bitwise – C

This note covers various types of pointers to be aware of and a few notations used with pointers. Types of Pointers Pointer: Pointer is a variable which holds the address of another variable NULL Pointer: A null pointer has a value reserved for indicating that the pointer does not refer to a valid object. It… Continue reading Pointer and Types – C
