void main()

int x,y,i;

int d,n=1;

int * r;

char h[16]={'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};

cout<<"Enter x : ";

cin>>x;

y=x;

while(x >= 10)

{

x/=10;

++n;

}

r=new int[n];

for(i=0 ; y >= 16 ; ++i)

{

r[i]=y%16;

y /= 16;

}

r[i++]=y;

cout<<"16 base = ";

for(i=(n-1) ; i>=0 ; --i)

{

cout<<h[r[i]];

}

cin.get();

}
