Question

Rewrwrtie the following C++ code to be able to take any decimal number and convert it to vegesimal number(to be used with linked list) *I have gotten this to work with numbers up to 600 but I know that there must be a loop that you can use on it. Can someone please figure this out for me. This is what I have so far:

#include <iostream>
using namespace std;

void Yea(int num);

int main()
{
   char ch;
   char response;
   int num;

   cout << "Decimal Number: ";
   cin >> num;

   Yea(num);

   cout << "Run again?: ";
   cin >> response;
   cout << endl;

   while((response=='Y')||(response=='y'))
   {
       cout << "Decimal Number: ";
       cin >> num;
       Yea(num);
       cout << "Run again?: ";
       cin >> response;
       cout << endl;
   }

   system("PAUSE");
   return 0;
}

void Yea(int num)
{
   char ch;
   char ch2;
   char ch3;
   int div;
   int rem;
   int temp;
   bool i;

   i=false;

   div=num/20;
   rem=num%20;

   cout << "Vigesimal number is: ";

   if(div>19)
   {
       temp=(div/20);
       num=(num%200);
       ch3=(48+temp);
       cout << ch3;
       i=true;
      
   }

   else
       ;

   if(i==true)
   {
       div=num/20;
       rem=num%20;
   }

   else
       ;

   if((rem>9)&&(div<10))//Number out front(ch) & letter in back(ch2)
   {
       ch=(48+div);
       ch2=(55+rem);
   }

   else if((div>9)&&(rem<10))//Letter out front(ch) & number in back(ch2)
   {
       ch=(55+div);
       ch2=(48+rem);
   }

   else if((div>9)&&(rem>9))//Letter out front (ch) & letter in back(ch2)
   {
       ch=(55+div);
       ch2=(55+rem);
   }

   else //Number out front(ch) & number in back (ch2)
   {
       ch=(48+div);
       ch2=(48+rem);
   }
      
       cout << ch << ch2 << endl << endl;
}

Explanation / Answer

#include <iostream>
#include <stdlib.h>
using namespace std;

void Yea(int num);

int main()
{
char ch;
char response;
int num;

cout << "Decimal Number: ";
cin >> num;

Yea(num);

cout << "Run again?: ";
cin >> response;
cout << endl;

while((response=='Y')||(response=='y'))
{
cout << "Decimal Number: ";
cin >> num;
Yea(num);
cout << "Run again?: ";
cin >> response;
cout << endl;
}

system("PAUSE");
return 0;
}

void Yea(int num)
{
char ch;
char ch2;
char ch3;
int div;
int rem;
int temp;
bool i;
   string ans="";
i=false;

cout << "Vigesimal number is: ";
while(num>0){
    rem=num%20;
    if(rem>9)ans=ans+(char)(65+rem-10);
    else ans=ans+(char)(48+rem);
  
    num=num/20;
   
}
for(int i=ans.length()-1;i>=0;i--)cout<<ans[i];
cout<<endl;

}
