Question

C++

Have the user type in 10 numbers. Then, using STL STACKs print a table showing each number followed by the next large number. For example, if the user types the following

7 5 12 25

The output should be this:

Element       Next Greater Number
   5      -->   7
   7      -->   12
   12     -->   25
   25     -->   -1

You can use this functor to sort the vector:

#include<iostream>
#include<vector>
#include<algorithm>
using namespace std;

struct greater
{
template<class T>
bool operator()(T const &a, T const &b) const { return a > b; }
};

int main()
{
vector <int> v = { 1,4,2,6 };
sort(v.begin(), v.end(), greater());
return 0;
}
