WRITE THE PROGRAM IN C++ PLEASE WITH INLINE COMMENTS.

Write a function that returns a decimal number from a binary string. The function header is as follows: int bin2Dec (const string & binarystring) For example, binarystring 10001 is 17 (1 times 2^4 + 0 times 2^3 + 0 times 2^2 + 0 times 2^1 + 1 times 2^0 = 17). So, bin2Dec ("10001") returns 17. b. Write a function that parses a decimal number into a binary number as a string. The function header is as follows: string dec2Bin (int value) For example, dec2Bin (17) returns string "10001". c. Write a test program that prompts the user to enter a binary or decimal number and display its equivalent value in decimal or binary
