Please find the java program to convert decimal number into modern roman equivalent :
DecimalToModernRoman.java :
import java.io.*;
class DecimalToModernRoman
{
public static void main(String args[]) throws IOException
{
BufferedReader br=new BufferedReader(new
InputStreamReader(System.in));
System.out.print("Input a Decimal Number : ");
int n=Integer.parseInt(br.readLine()); //Input the decimal
number
if(n>0 && n<4000) //Enter the number in range
1-3999
{
//Decimal numbers equivalent to roman numbers
String thousands[]={"","M","MM","MMM"};
String
hundreds[]={"","C","CC","CCC","CD","D","DC","DCC","DCCC","CM"};
String
tens[]={"","X","XX","XXX","XL","L","LX","LXX","LXXX","XC"};
String
units[]={"","I","II","III","IV","V","VI","VII","VIII","IX"};
int ts=n/1000;
int h=(n/100)%10;
int t=(n/10)%10;
int u=n%10;
// Print the roman equivalent
System.out.println("The modern roman equivalent of decimal number "
+n );
System.out.println("is - "
+thousands[ts]+hundreds[h]+tens[t]+units[u]);
}
//Error message
else
System.out.println("Entered number is out of Range.Enter in range
of 1-3999");
}
}

Write up a detailed solution to the problem: Design a program to convert a Roman numeral to a decimal number. The program should read a Roman numeral. You may read it as a string or one character at a time. Do the conversion and then output the decimal number. Here are the “letters” you need to know: Symbol = Value I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M =...
(c++) Write a program that converts a positive integer into the Roman number system.(c++) Roman numbers. Write a program that converts a positive integer into the Roman number system. The Roman number system has digits I 1 V 5 X 10 L 50 C 100 D 500 M 1,000 Numbers are formed according to the following rules. (1) Only numbers up to 3,999 are represented. (2) As in the decimal system, the thousands, hundreds, tens, and ones are expressed separately....
Write and test a function toDecimal() that converts a roman number such as MCMLXXVII to its decimal number representation. Write a main program to test the function. Your function should have two arguments - the roman number as a string, and an error processing function. Write a helper function that will return the numeric value of each of the letters used in roman numbers. Then convert the string argument as follows look at the first two characters. If the first...
How do i write a program to read muliple files? i can read one but i need to read 10: 0.txt - 9.txt Here is the code for reading one but i need to read 10 text files and print the frequencies of all the letters a - z, upper and lowercase, in one take. here is the output i should get #include <stdio.h> #include <stdlib.h> #include <string.h> #include <omp.h> int main() { double start_time = omp_get_wtime(); char str[1000); int...

Write a Java program to convert octal (integer) numbers into their decimal number equivalents (exactly the opposite of what you have done in Assignment 4). Make sure that you create a new Project and Java class file for this assignment. Your file should be named “Main.java”. You can read about octal-to-decimal number conversions on wikepedia Assignment 4 is at the bottom Objective Your program should prompt the user to enter a number of no greater than 8 digits. If the...
1 Overview For this assignment you are required to write a Java program that plays (n, k)-tic-tac-toe; (n, k)-tic- tac-toe is played on a board of size n x n and to win the game a player needs to put k symbols on adjacent positions of the same row, column, or diagonal. The program will play against a human opponent. You will be given code for displaying the gameboard on the screen. 2 The Algorithm for Playing (n, k)-Tic-Tac-Toe The...
Assignment Λ You shall write a Java program that accepts 5 command-line arguments and generates an image of a Sierpinski triangle, as a 24- bit RGB PNG image file. Specifications The command-line arguments shall consist of the following 1. The width (in pixels) of the image, as a positive decimal integer 2. The height (in pixels) of the image, as a positive decimal integer 3. The minimum area (in pixels) that a triangle must have in order to be drawn,...
