Basically i am really close (i think) and the numbers im getting when i run it are weird like for instance i should get back a one if i enter in I or i but instead im getting like 178976087.

#include "stdafx.h"

About exercise 7 of chapter 10 of PPP (page 372): changing the calculator to gives us the result of the roman numerals, like XXI + CIV = CXXV.
At *first* time there are two solutions for solving it in my mind.
First is, giving each roman number to a function like the one existing in exercise 6 and then get their integer numbers and then calculate them by the calculator of chapter 7 and finally make a function to convert the result to roman mode. (simpler)
Second is to change the calculator from chapter 7 to calculate roman numbers inside itself and gives the result again in roman mode. (harder)
As an important step of ‘solving the problems’/’programming’, how can I make decision to choose a solution for solving a problem.
I am writing a program that converts arabic numbers into roman numerals.
Quote Write a program that asks the user to enter a number within the range of 1 through 10. Use a switch statement to display the Roman numeral version of that number.
Input Validation: Do not accept a number less than 1 or greater than 10.
Prompts And Output Labels. Use the following prompt for input: "Enter a number (1 - 10): ". The output of the program should be of the form "The Roman numeral version of A is R" where A is the Arabic numeral entered (1,2,3,...) and R is the all-capitals form of a Roman numeral, such as VII.
how to convert integers -> Roman Numerals using both if & switch statement.
View 3 Replies View RelatedHere is the problem:"Write a program that converts a number entered in Roman numerals to a positive integer. Your program should consist of a class, say, romanType. An object of type romanType should do the following:
a. Store the number as a positive integer.
b. Convert and store the number as a positive integer.
c. Print the number as a Roman numeral or positive integer as requested by the user.
The integer values of the Roman numerals are:
M 1000
D 500
C 100
L 50
X 10
V 5
I 1
d. Test your program using the following Roman numerals: MCXIV, CCCLIX, MDCLXVI."I'm doing the best I can to understand the concept of the class. Here is what I have (which is not much thus far, and nowhere near correct I'm sure).
#include<iostream>
#include<iomanip>

Program to convert a date entered into roman numerals. I can only use one output prompt to get the date, so that makes it more difficult. Here is what i have, but how to go about the rest of it.

using namespace std;
int array_date[20];
char I; // one

#include "stdio.h"

I've Been working on a program that acts as a form of Roman numeral calculator, I input Roman Numeral Characters, and the program (is suppose to) output the corresponding digits. *Not allowed to use for loops or arrays.
Input:
MCCXXVI
LXVIIII
+
Output:
The First number is 1226
The second number is 69
Arithmetic operation is +
the sum of 1226 and 69 is MCCLXXXXV (1295)
However, when I run the program:
input:
MCCXXVI
LXVIIII
+
Output:
The first number is 77
The second number is 76
Arithmetic Operation is +
The sum of 77 and 76 is (infinite loop of I's) (153)
I noticed that when I input MCCXXVI, it only takes the first character (I thought cin.get() was suppose to stop this?), and returns the ASCII decimal value of that, instead of the integer value that I assigned to each letter. Why i get an infinite loop, and how to fix it.

So I am trying to write a program that converts roman numerals into decimal numbers. I so far have come up with:
Code:
#include <stdio.h>
#include <ctype.h> // importing the tolowerfunction
//variables
int decimal, total;
char numeral[];
[Code] .....
But each time I compile it, it times out as if it were hitting an infinite loop. I have a feeling that I am not passing an individual character to the roman_to_decimal function but am unsure why.
I have a fascination with Roman numerals and would like to create a C program that converts Roman numeral inputs to normal numbers.
I want to keep everything simple and only use the C library for the coding.
This program compiles, but has a bunch of logical errors. I know my problem is somewhere in the while loop that I have, but I can't figure out where. Here are some of the issues I am experiencing:
1. At the beginning of the program it asks you to enter a number, and when you do it does nothing while proceeding to the while loop where I have it asking the same question
Code:
"Please enter a number between 1 and 20 (Enter 0 to stop)
";
cin >> num;
cout << endl;
I want to be able to eliminate that first statement but if I only run this in the loop without the above statement the program will display nothing on the screen and proceeds to stop.
2. This code runs fine, except that if you make a mistake, it will prompt you to enter a valid number, however; it ignores your first response if the number you enter is valid and asks you to enter a valid number anyway. Once you enter it a second time, it will accept it and the program will continue on.
Code:
while(num != SENTINEL) {
cout << "Please enter a number between 1 and 20 (Enter 0 to stop) ";
cin >> num;
cout << endl;
Also if you type in 0 on your first response, it will prompt you that it is not a valid number and ask you to try again, instead of stopping the program like it is supposed to do. On your second response the program will accept your 0 and stop the program correctly.
//Write a program that displays the roman numeral equivalent of any decimal number between 1 and 20 that the user enters. The roman numerals should be stored in an array of strings and the decimal number that the user enters should be used to locate the array element holding the roman numeral equivalent. The program should have a loop that allows the user to continue entering numbers until an end sentinel of 0 is entered.
Input validation: Do not accept scores less than 0 or greater than 20
#include <iostream>
#include <string>
using namespace std;
int main() {
// Declare constants and variables
const int romanNum = 21; // Size of the elements in the array

this program is supposed to turn Arabic Numbers into Roman Numerals, but after making the program shown below I only am able to get some alt codes to show up (I got a green lantern symbol to show up)
How would I fix this program to show Roman numerals?

so my homework assignment is to make a program of which removes any notes in a program file.
for example, you run my program it will ask for a filename, when entered it opens the file, copies everything in it and removes any double forward slashes (//) and anything after that up to the new line character ( ) and anything between /* and */ including the /* and */.
i created the entire program and it removed the // and anything after that up to the new line character but will not remove anything after the first / when it finds a /*. This includes the */ at the end of the comment.
the section of code that removes the comments is
//this loop removes all notes
for(i=0;i<buf.st_size;i++) {
if((filecontent[i]=='/')&&(filecontent[i+1]=='/'))//removes notes using //
{
for(i=i;filecontent[i]!='
';i++)
filecontent[i]=' ';}
[Code]....
i know that the section that removes the multi line comments would not remove the final */ at the end if it did work, i was planning to fix that later once it removed the comment.

My program is ruuning perfectly only problem is that i must transform it to program uses class, class student . Am very beginer in using classes, so far i do very easy programs using classes.
so far i have this
#include "stdafx.h"
#include "student.h"
student::student(vector<STUDENT> studenti) {
vStudent=studenti;

I try to make it but its too difficult for me. in that student.h and student .cpp is 50 errors..
Here is my code

#include <string>
#include <vector>
#include <sstream>

I've been working on a small SDL program and decided I wanted to throw the program on to a disc so I could show some people what I'm working on. However, when I try to run the executable, the program crashes and under more details it says that the fault lies on SDL2_ttf.dll .
Why does this program work inside of VS2012e and not in windows?
What I did :
Set the program to release, hit f6, and then tried to run the executable from windows.
Additional information :
Compiler : Visual Studio 2012 express
O/S : Windows 7 64bit
SDL lib : 32 bit version
For instance Code: int counter;
counter =0;
FILE *pfile;
pfile= fopen("g:myprog.txt" "w");
while (counter >100)
{ fprintf (case counter{something})}; how do I do this?
Cannot divide the real output of the AVERAGE.:

#include<conio.h>

is there anyway to have a program where it ask for three numbers and you shows which which number is the largest and which is the smallest, e.g.
Enter 1st number: 30
Enter 2nd number: 10
Enter 3rd number: 30
Largest = 30
Smallest = 10
I am working on a program to compute the natural log of numbers using several different methods, but I am having a couple of issues. Firstly, when using Borchardt's Algorithm I almost always end up with nan as a result, even though I am pretty sure I got the formula correct. Also, in my lnDemo.c file It doesnt give me the correct answer and the second time around I get a segmentation fault.
Code:
//myLog.h-------------------------------------------------------
//These functions will compute or aproximate the natural log of a number
//This method will use a formula to compute it
int lnFormula(double x, int m,double *result);
