I wrote two programs, this one:
#include<iostream>
using namespace std;
main()
{
char rom,invalid;
double tot;
tot=0;
cout<<"Please enter Roman numerals ending with a period."<<endl;
while (rom != '.')
{
cin.get(rom);
if(rom=='M' || rom=='m')
{
tot=tot+1000;
}
else if(rom=='D' || rom=='D')
{
tot=tot+500;
}
else if(rom=='C' || rom=='C')
{
tot=tot+100;
}
else if(rom=='L' || rom=='l')
{
tot=tot+50;
}
else if(rom=='X' || rom=='x')
{
tot=tot+10;
}
else if(rom=='V' || rom=='v')
{
tot=tot+5;
}
else if(rom=='I' || rom=='i')
{
tot=tot+1;
}
else
{
invalid;
}
}
cout<<"The value in Roman numerals is "<<tot<<endl;
system("PAUSE");
return EXIT_SUCCESS;
}and this one:
#include <iostream>
using namespace std;
int main()
{
char repeat='y';
while (repeat=='y' || repeat=='Y')
{
cout << "Enter a number to convert to Roman numerals ";
int num;
cin >> num;
while (num >=1000) {
cout <<"M";
num = num - 1000;
}
while (num ==900) {
cout <<"CM";
num = num - 900;
}
while (num >=500) {
cout <<"D";
num = num - 500;
}
while (num ==400) {
cout <<"CD";
num = num - 400;
}
while (num >=100) {
cout <<"C";
num = num - 100;
}
while (num >=90 && num<=99) {
cout <<"XC";
num = num - 90;
}
while (num >=50) {
cout <<"L";
num = num - 50;
}
while (num ==40) {
cout <<"XL";
num = num - 40;
}
while (num >=10) {
cout <<"X";
num = num - 10;
}
while (num ==9) {
cout <<"IX";
num = num - 9;
}
while (num >=5) {
cout <<"V";
num = num - 5;
}
while (num ==4) {
cout <<"IV";
num = num - 4;
}
while (num >=1) {
cout <<"I";
num = num - 1;
}
cout<<endl;
cout<<endl;
cout<<endl;
cout<<"\nWould you like to repeat this program? (y or n)"<<endl;
cin>>repeat;
system("cls");
}
cout<<"Thank you for using this program\n";
system("PAUSE");
return EXIT_SUCCESS;
}I want the first program to be like the second, so that When I type IV it prints out 4 instead of 6... i know the cin.get command reads each character by itself, so i cant put something like
if(rom=='IV' || rom=='iv')
{
tot=tot+4;
}so is there a way to make it check the next character in line when it enters the if statement?? and if false, to exit that statement, and go on to the next?
