C++ program to Convert Decimal to Hexadecimal



C++ program to Convert Decimal to Hexadecimal

Decimal number have base 10 and Hexadecimal number have base 16.

#include<iostream.h>
#include<conio.h>

void main()
{
int num,rem[20],hex=0,i=0,j;
clrscr();
cout<<"Enter any Number: ";
cin>>num;
while(num>0)
  {
    rem[i] = num % 16;
    num = num / 16;
    i++;
  }
cout<<"Hexadecimal number : ";
for(j = i - 1 ; j > = 0 ; j--)
  {
    switch(rem[j])
    {
      case 10:
	  cout<<"A";
	  break;
      case 11:
	  cout<<"B";
	  break;
      case 12:
	  cout<<"C";
	  break;
      case 13:
	  cout<<"D";
	  break;
      case 14:
	  cout<<"E";
	  break;
      case 15:
	  cout<<"F";
	  break;
      default :
	 cout<<rem[j];
    }
  }
