Given a binary number as input, we need to write a program to convert the given binary number into an equivalent decimal number. The stoi() function is relatively new, as it was only added to the language as of its latest revision (C++11) in 2011. The decimal numbers have a base of 10, as 10 possible digits are ranging from 0,1,2 9. Here is another way to convert decimal to binary numbers which is more intuitive and faster. Take Binary number as input. When we convert a binary number to a decimal number, we multiply each digit by (2n2^n2n). At every iteration we extract the last digit (or a character in case of string input), check if it is a 1, if it is then multiply by the power of 2(where the power depends on which bit we are currently on ) and add it to the decimal number( initially = 0 ) .If it is a 0, then we dont need to add anything to our decimal value since that bit is not contributing, so just increase the power and move to the next bit. In the same way, conversion of Binary to Decimal, Decimal to Octal and Octal to Decimal, Octal to Binary and Binary to Octal also can be done. Enter a binary number above in the input section. The idea is to extract the digits of a given binary number starting from the rightmost digit and keep a variable dec_value. Analysis of Algorithms.
