How to Make a Full-Out Calculator

First start with

#include <cstdlib>
#include <iostream>
#include <math.h>

using namespace std;

//Basic Functions
double basfunc(double x, double y)
{
   double sum, dif, pro, quo ; //add, subtract, multiply, divide
   sum=x+y ;
   dif=x-y ;
   pro=x*y ;
   quo=x/y ;
   int operb ;
   cout<<"Enter an operation. 1-add, 2-subtract, 3-multiply, 4-divide." <<endl ;
   cin>> operb ; //operation basic
   switch (operb)
   {
      case 1:
         cout<<sum <<endl ;
         break ;
      case 2:
         cout<<dif <<endl ;
         break ;
      case 3:
         cout<<pro <<endl ;
         break ;
      case 4:
         cout<<quo <<endl ;
         break ;
   }
}
//we will add int main() later

Next we will make the "Next" functions

//Next Functions
double nextfunc(double x_2, double y_2)
{
   double sqrx=x_2*x_2 ; //x squared
   double sqrtx=sqrt(x_2) ; //square root of x
   double cubx=sqrx*x_2 ; //x cubed
   //got to go this is where we will do cube roots
}
