Question

I have this matlab program, and need to turn it into a C++ program. Can anyone help me with this?

% Prompt the user for the values x and y

x = input ('Enter the x coefficient: ');

y = input ('Enter the y coefficient: ');

% Calculate the function f(x,y) based upon

% the signs of x and y.

if x >= 0

   if y >= 0

       fun = x + y;

   else

       fun = x + y^2;

   end

else

  if y >= 0

      fun = x^2 + y;

  else

      fun = x^2 + y^2;

  end

end

% Write the value of the function.

disp (['The value of the function is ' num2str(fun)]);

Answer 1

#include <iostream>
using namespace std;

int fun(int x,int y)
{
int func_value;
if(x>=0)
{
if(y>=0)
func_value= x + y;
else
func_value= x + y*y;
}
else
{
if(y>=0)
func_value= x*x + y;
else
func_value= x*x + y*y;
}
return func_value;
}

int main()
{
int x,y,returnValue;
cout<<"Enter the x coefficient : ";
cin>>x;
cout<<"Enter the y coefficient : ";
cin>>y;
  
returnValue=fun(x,y);
  
cout<<"The value of the function is : "<<returnValue;
return 0;
}
