Write a C++ Program to find the distance between two points

This program calculates the distance from intial point (X1,Y1) to Final Point(X2,Y2)

#include<iostream>
#include<math.h>
using namespace std;


class dist
{
    int a,b,c,d;
public:
    void get()
{
    cout<<"\n Enter the  value of (X1,X2) and (Y1,Y2):";
    cin>>a>>b>>c>>d;
}
    void calc()

{    int k;
    float l;
    k=( pow(c-a,2)  +   pow(d-b,2)  );
    l=pow(k,0.5);   
    cout<<"\n Distance between point(X1,Y1) and (X2,Y2) is: "<<l << "\n\n";
}
};


int main()
{
   
    dist m;
    m.get();
    m.calc();

return 0;
}

Output:
