Write a function that returns a decimal number from an octal number. The function header is as follows: int octal2Dec(const int& octalNumber) For example, octalNumber 345 is 229 (3 * 82 + 4 * 81 + 5 * 80 = 229). So, octal2Dec("345") returns 229. Write a test program that prompts the user to enter an octal number and displays its decimal equivalent value.
