C++ Program

3. Input an integer containing only 0s and 1s (i.e., a "binary" integer) and print its decimal equivalent. Use the modulus and division operators to pick off the "binary" number's digits one at a time from right to left. 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 which is 13. You can find if the least significant digit is O or 1 by using modulo 10 and looking at the remainder. You can get rid of the least significant digit (making 1101 into 110) by dividing the number by 10
