Programming In C, 3rd Edition

Loop Control 187

Explanation:

A binary number is initialized in an array. The first element of the array is assigned to vari-

able ‘y’. The logic used here is to multiply by 2 the variable ‘y’ and add the next successive

bit. For this the equation y=y*2+x[i+1] is used. The number of iterations to be carried out

is equal to the number of binary bits minus 1. Here, five bits are initialized, hence the number

of iterations will be four.

6.43 Write a program to add a parity bit with four binary bits such that the total number of one’s

should be even.
