Ritchie at the Bell Telephone Laboratories to develop the UNIX operating system.It keeps fluctuating at number one scale of popularity along with Java programming language, which is also equally popular and most widely used among modern software programmers.
C# File.Copy Code That RunsC was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language.This C tutorial will give you enough understanding on C programming language from where you can take yourself to higher level of expertise.A basic understanding of any of the programming languages will help you in understanding the C programming concepts and move fast on the learning track.

March 2015 ) ( Learn how and when to remove this template message ). Instead of performing on individual bits, byte-level operators perform on strings of eight bits (known as bytes) at a time. The reason for this is that a byte is normally the smallest unit of addressable memory (i.e. It is just a representation of AND which does its work on the bits of the operands rather than the truth value of the operands. Bitwise binary AND does the logical AND (as shown in the table above) of the bits in each position of a number in its binary form. Its result is a 1 if one of the either bits is 1 and zero only when both bits are 0. The result is zero only when we have two zeroes or two ones. Thus i i 1 when used in a loop toggles its values between 1 and 0. Thus we get the bits inverted, for every bit 1 the result is bit 0 and conversely for every bit 0 we have a bit 1. This operation should not be confused with logical negation. The number following the operator decides the number of places the bits are shifted (i.e. Thus by doing ch 3 all the bits will be shifted to the right by three places and so on. When performed on an unsigned type, the operation performed is a logical shift, causing the blanks to be filled by 0 s (zeros). When performed on a signed type, the result is technically undefined and compiler dependent, 5 however most compilers will perform an arithmetic shift, causing the blank to be filled with the sign bit of the left operand. It shifts each bit in its left-hand operand to the left by the number of positions indicated by the right-hand operand. Each of the compound bitwise assignment operators perform the appropriate binary operation and store the result in the left operand. However, logical operators treat each operand as having only one value, either true or false, rather than treating each bit of an operand as an independent value. Logical operators consider zero false and any nonzero value true. Another difference is that logical operators perform short-circuit evaluation. This is because a logical operator must treat any nonzero value the same. To be used as a logical operator requires that operands be normalized first. A logical not applied to both operands wont change the truth table that results but will ensure all nonzero values are converted to the same value before comparison.
