/*HEllo everybody. i would like to see your recommendations and your quotes.
how can i optimize this code?
what is wrong into the code?
what can it be improved?*/
/*4.28 (Printing the Decimal Equivalent of a Binary Number)
Input an integer containing only 0s and 1s (i.e., a “binary” integer)
and print its decimal equivalent. Use the remainder and division
operators to pick off the “binary” number’s digits one at a time from
right to left. Much as in the decimal number system, where the
rightmost digit has a positional value of 1, the next digit left has a
positional value of 10, then 100, then 1000, and so on, in the
binary number system the rightmost digit has a positional value of
1, the next digit left has a positional value of 2, then 4, then 8, and
so on. Thus the decimal number 234 can be interpreted as 2 * 100
+ 3 * 10 + 4 * 1. The decimal equivalent of binary 1101 is 1 * 1 + 0
* 2 + 1 * 4 + 1 * 8 or 1 + 0 + 4 + 8, or 13.*/
