in c$++$ Unary operator overloading

Create $$ProblemSolution$$ class which demonstrate unary operator overloading.

The class must have following characteristics.

Integer member variable N$.$

A constructor to initialize the value of N$.$

Overload $++$ operator which increments the value of N by $1.$

Input

$12$

Output

$13$

Assume:

N is an integer within the range $[-2,000,000,000$ to $2,000,000,000].$

#include

using namespace std;

class ProblemSolution

$\{$

private:

int N;

$//$write your code here

void Display$()\{$

cout$<<$ N;

$\}$

$\}$;

int main$()$

$\{$ int N ;

cin$>>$N;

ProblemSolution problemSolution$($N$)$;

$++$problemSolution;

problemSolution.Display$()$;

return $0$;

$\}$
