C++, as basic as possible, dont use another function, just put everything inside int main

2) Decimal to Roman Numeral Conversion The ancient Roman numbering system employed a sequence of letters to represent numeric values. Values were obtained by summing individual letter values in a left-to-right fashion. The value of individual Roman numerals is provided in the following list: I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M = 1000 In Roman numbers, larger numeral values generally appear before smaller values, and no single numeral may be repeated more than 3 times in a row. There are a few numbers that cannot be represented with these restrictions, so an additional rule was provided to deal with these cases: if a higher value numeral is preceded by a single smaller numeral, the smaller value is subtracted from the larger one. This rule is only applied to a small number of cases: IV (4), IX (9), XL (40), XC (90), CD (400) and CM (900). Using these simple rules, we can construct a method to convert an integer (decimal) value to a Roman number as follows: Step 1: If the value of the number is in [900,999) output CM If the value is in (500,899) output D If the value is in [400,499) output "CD" If the value is in (100,399) output "C" If the value is in (90,99) output XC" If the value is in (50,89) output "L" If the value is in [40,49) output "XL" If the value is in (10,39) output X If the value is 9, output IX If the value is in (5,8) output V If the value is 4, output IV If the value is in (1,3), output I Step 2: Subtract the value of the 1 or 2 letter sequence that was just output from the integer number value, producing a 'remainder.' For example, if the original number was 93, the program would have printed XC in Step 1, and then, in this step, subtracted 90 to get a remainder of 3, and then continued with 3 as the number. Step 3: Repeat the process until the remainder value is zero. Using this method, write a program that does the following: Reads in an integer value from 1 to 999, inclusive. Checks to make sure the input value is > and
