2d Parity Check Program C - hatfasr. Mame 0.139 u1 full romset. Parity check of a word. C / C Forums on Bytes. The basics are that GxP^t 0 mod 2 (for even parity) or GxP^t 1 mod 2. (for odd parity). The notation '^t' denotes the transposed of a matrix. Given you can compute P^t and hence P. That is, the rows have been encoded using odd parity and the last row holds the parity bits of the columns which have also been encoded using odd parity. There are two possible interpretations of the corner parity bit in the last block – it can either check the row or column parity. In this example, it has been used to check the column parity.

In this tutorial, we are going to learn how to find parity of a number efficiently in C++. Here we will learn about the parity of a number, algorithm to find the parity of a number efficiently, and after that, we will see the C++ program for the same.

Parity of a number

Parity of a number is a term used to tell that the total number of set bits(1’s) in its binary representation is even or odd. It is of two types:-
1. Even Parity: If the total number of set bits (1’s) is even, then that number has even parity.
2. Odd Parity: If the total number of set bits (1’s) is odd, then that number has odd parity.
For example:-
12 has even parity because it has an even number of set bits in its binary representation i.e ‘1100’.
14 has odd parity because it has an odd number of set bits in its binary representation i.e ‘1110’.

Efficient Algorithm to find parity of a number

Oxford reading circle primer pdf. The most efficient way of finding the parity of a number is by using XOR and shifting operator as shown below.
b = n ^ (n >> 1);
b = b ^ (b >> 2);
b = b ^ (b >> 4);
b = b ^ (b >> 8);
b = b ^ (b >> 16);

In the above operations, we use XOR and left shift operator. We are shifting double bits of the previous operation. And taking the XOR with that number. We know that 0 XOR 1 or 1 XOR 0 is 1, otherwise 0. So when we divide the binary representation of a number into two equal halves by length & we do XOR between them, all different pairs of bits result into set bits in the result number i.e “b” here.

Now, after the above operations b contain the rightmost bit of b and represent the parity of n. If the rightmost bit is 1, then n will have odd parity and if it is 0 then n will have even parity.
We check the odd or even by using bitwise AND operator. If (b & 1) is true means odd else even. Download microsoft office 2007 free.
