 cout<<“Enter value of a:”; 56 is greatest.
 cin>>a;
 cout<<“ Enter value of b:”;
 cin>>b;
 c=a>b?a:b; //using conditional operator, c stores the
biggest of two values.
 cout<<a<<“ is greatest”;
 getch();
}

5.Program to find greatest of two values using conditional
operator.
 class comparison
 {
 public:
 int a1,b1,max;
 int greatest (int a1,int b1)
 {
 max=a1>b1?a1:b1; //using conditional(ternary operator) to compare a and b, storing result in max.
 return max;
 }
 };
 void main()
 {
 int a, b;
 clrscr(); OUTPUT
 cout<<"enter a:";
 cin>>a;
