Firstly, initialize the decimal_num variable with the value 0, add the binary number in the bin_num variable, and initialize rem. cout << The decimal conversion of << num << is << dec; These C++ programming codes are some of the elementary programs taught in the introduction sections of programming courses. Therefore, arr[2] = 0. The same step 2 is repeated until there will be no digit left. Suppose n = 13. The below diagram explains how to convert ( 1010 ) to equivalent decimal value: Below is the implementation of the above idea : Note: The program works only with binary numbers in the range of integers. Step 3: Repeat the above two steps until the number is greater than zero. Step 1: Divide the number by 2 through % (modulus operator) and store the remainder in array. 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. Step 3: Repeat the step 2 until the number is greater than zero. By this way, we can do binary to decimal conversion. When the computer performs calculations within its system, the binary number thus calculated needs to be displayed to the user through a decimal number.
