Problem: Write a C++ program to convert a binary number (that may contain a fractional part) into its corresponding decimal value. The program should take two binary values as input, one representing the number before the radix point and the other representing the number after the radix point. The program should convert the binary values into their corresponding decimal values and print the resulting value rounded to two decimal places. The program should use functions to convert the integer and fractional binary parts into integer and double values, respectively, and add the integer and double values to obtain the final decimal value. The program should use the cout statement to print the resulting value with two digits after the decimal point.
