Write a program in C++ to print numbers in descending order using recursion. Example call: Reverse(5) Output: 5 4 3 2 1

Write a C++ program using classes and recursion functions to convert a number in a given base (the user enters the base - from 2 to 9) to a decimal number. The algorithm states that each successive digit in the number is multiplied by the base raised to the power corresponding to its position in the number. The low-order digit is in position 0. We sum together all of these products to get the decimal value. For example, in binary – base 2, if we have the binary number 111001, we convert it to decimal as follows: 1x 25+1x 24+1x23+0x2²+0x 21+1x 2º=57 For a base 5 number, 14230: 1x54+4x53+2x52+3x51+0 x 50=1190 Validate your input. You should check for invalid digits and provide an informative error message to the user. This program requires you to use a recursive function for the conversion to decimal. Failure to do that will result in no points awarded.

In C++ Consider the following recursive function (Chapter 17, #9, modified)   void recFun(int x) {       if (x > 10)       {            recFun(x / 10);            cout<< x % 10;       }       else            cout<< x; }   How can the code be modified so that the sum of all digits is printed?
