My homework is to write a simple c program that converts numbers into roman numerals. The only functions that i am allowed to use are printf and scanf. I have written the code, however i don't know how to print out numbers such as \"25, 13, 93, 66\" etc. Any help would be appreciated! thank you! (below is the written code)

Here you will get program to convert decimal number to roman numeral in C and C++.How it Works?Divide the given number in the order 1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1 to find largest base value.Display the corresponding roman symbol of largest base value obtained by above method in output.Subtract the given number with largest base value to get new number.Repeat above process with the new number until it becomes 0.if(typeof ez_ad_units!='undefined')ez_ad_units.push([[728,90],'thecrazyprogrammer_com-medrectangle-3','ezslot_9',124,'0','0']);__ez_fad_position('div-gpt-ad-thecrazyprogrammer_com-medrectangle-3-0');Example:Decimal Number: 250if(typeof ez_ad_units!='undefined')ez_ad_units.push([[336,280],'thecrazyprogrammer_com-medrectangle-4','ezslot_8',125,'0','0']);__ez_fad_position('div-gpt-ad-thecrazyprogrammer_com-medrectangle-4-0');Divide it in order 1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1 to find largest base value. Here 250 is divided by 100. The corresponding roman symbol for 100 is C.Subtract 250 with 100 (largest base value in previous step) to get new number i.e. 150.Again divide 150 in the order mentioned earlier. It is divided by 100, so corresponding roman symbol is C.Subtract 150 with 100 to get new number i.e. 50.Divide 50 again in the order mentioned earlier. 50 is divided by 50, so corresponding roman symbol is L.Subtract 50 with 50. The new number obtained is 0 so we stop here.The final roman numeral is CCL.Below program implements above algorithm.Program to Convert Decimal Number to Roman Numeral in C

1. Take a decimal number as input.2. Check if the number is greater than 1000 or 900 or 500 or 400 or 100 or 90 or 50 or 40 or 10 or 9 or 5 or 4 or 1.3. If it is, then store its equivalent roman number in a array.4. Repeat the step 2-3 with the left over number.

My last few articles have given me a chance to relive my undergraduatecomputer science degree and code a Roman numeral to decimal converter.It's quite handy when you're watching old movies (when was MCMLVIIanyway?), andthe basic coding algorithm was reasonably straightforward. (See Dave's \"RomanNumerals and Bash\" and \"MoreRoman Numerals and Bash\".)

It is a problem frequently asked in interviews of top IT companies like Google, Amazon, TCS, and Accenture, etc. By solving the problem, one wants to check the logical ability, critical thinking, and problem-solving skill of the interviewee. So, in this section, we are going to discuss how to convert integer to roman in Java with different approaches and logic. Also, we will create Java programs for the same.

Roman numerals are the symbolic representation of numbers. These are usually used in watch faces, music theory, etc. There are seven letters used to represent roman numerals. The following table represent the roman numerals and corresponding decimal values.

It is usually written in highest to lowest from left to right, except some special cases (where the left character is less than the right character). For example, in roman numerals IV is equivalent to 4. It cannot be written as IIII.

An approach to convert integer to roman numeral is simple. First, create two arrays one for storing the values of roman numerals and second for storing the corresponding letters. Create an instance of the StringBuilder Class. Now compare the integer with roman numerals and do the following:

Roman numerals were used until the late Middle Ages (1500 CE), but in our modern world they still have their uses! You see roman numerals on clocks, paper currency, buildings, monuments, and even movie credits.

The above code defines exactly the same as the table in the previous section. Every decimal value has a roman numeral, such as C = 100. Both arrays have exactly the same amount of items, so we can use identical index numbers to look up numerals by decimals.

There is a common belief that any smaller digit placed to the left of a larger digit is subtracted from the total, and that by clever choices a long Roman numeral can be \"compressed\". The best known example of this is the ROMAN() function in Microsoft Excel, which can turn 499 into CDXCIX, LDVLIV, XDIX, VDIV, or ID depending on the \".mw-parser-output .monospacedfont-family:monospace,monospaceForm\" setting.[24] There is no indication this is anything other than an invention by the programmer, and the universal-subtraction belief may be a result of modern users trying to rationalize the syntax of Roman numerals.

Certain romance-speaking countries use Roman numerals to designate assemblies of their national legislatures. For instance, the composition of the Italian Parliament from 2018 to 2022 (elected in the 2018 Italian general election) is called the XVIII Legislature of the Italian Republic (or more commonly the \"XVIII Legislature\").

The Roman numerals chart can prove to be very helpful when converting a Roman numeral to an integer value or vice versa. The following Roman numerals list shows how the numbers are expressed in Roman numerals.

As mentioned above there are seven Latin letters that are used to represent Roman numerals. By changing the placement of these letters we can convert a natural number into a Roman numeral. Similarly, the converse operation can also be performed.

In addition to these basic conversions, there are a couple of rules that need to be remembered while converting Hindu-Arabic numbers to Roman numerals and vice versa. You can use the Roman Numerals Calculator to verify your answers.

Roman numerals worksheets can promote a better understanding of reading and writing Roman numerals. It consists of problems like converting numbers to Roman numerals and vice versa, word problems, etc. The following list shows a few pages of Roman numerals worksheets with downloadable pdfs.

To convert Hindu-Arabic numbers to Roman Numerals, we split the numbers into their least expandable form, write their respective Roman letter and add or subtract them. For example, 2021 in Roman numerals: 2021 = 1000 + 1000 + 10 + 10 + 1 = MMXXI

To convert Roman numerals to numbers, we split the Roman numerals into single letters, write their numerical values and add or subtract them, i.e., XII = X + I + I = 10 + 1 + 1 = 12. Here is a list of pages that express the Hindu-Arabic form of a few Roman numerals.

Roman numerals can be easily converted into numbers if we remember the basic rules of Roman numerals. However, a simple way to write the Roman numerals in Hindu-Arabic numbers is to expand the given Roman number and then add all of them together. For example, if we have XVII, we can expand and add them as, X + V + I + I = 10 + 5 + 1 + 1 = 27. We also need to remember the rules given below.

In order to write a date in Roman numerals, we use the following procedure. Let us convert the date 14 - 10 - 2021 to Roman numerals. So, 14 will be XIV, 10 will be X, and 2021 will be MMXI. Now, this will be together written as XIV - X - MMXI.

If you see boxes in the code below, those are supposed to be the Unicode combining overline (U+0305) and look like IVXLCDM. Or, if you see overstruck combinations of letters, that's a different font rendering problem. (If you need roman numerals > 3999 reliably, it might best to stick to chiseling them in stone...)

Explanation: R1000's definition contains rows representing each of 10 different digits in the 100s, 10s and 1s column (the first entry in each row is blank -- each entry is preceded by a space). R1000 itself represents the first 1000 roman numerals (the cartesian product of these three rows of roman numeral \"digits\" which is constructed so that they are in numeric order. And the first entry -- zero -- is just blank). To convert a number to its roman numeral representation, we will separate the number into the integer part after dividing by 1000 (that's the number of 'M's we need) and the remainder after dividing by 1000 (which will be an index into R1000).

The non-ceremonial work in this program starts at the function to_roman/1. Unusually for Mercury the function is semi-deterministic. This is because some of the helper functions it calls are also semi-deterministic and the determinism subsystem propagates the status upward. (There are ways to stop it from doing this, but it would distract from the actual Roman numeral conversion process so the semi-determinism has been left in.)

to_roman/1 is just a string of chained function calls. The number is passed in as a string (and the main/2 predicate ensures that it is *only* digits!) is converted into a list of characters. This list is then reversed and the Roman numeral version is built from it. This resulting character list is then converted back into a string and returned.

build_roman/1 takes the lead character off the list (reversed numerals) and then recursively calls itself. It uses the promote/2 predicate to multiply the ensuing Roman numerals (if any) by an order of magnitude and converts the single remaining digit to the appropriate list of Roman numerals. To clarify, if it's passed the number \"123\" (encoded by this point as ['3', '2', '1']) the following transpires:

R has a built-in function, as.roman, for conversion to Roman numerals. The implementation details are found in utils:::.
