Thread: Passing structures to a function?

If you wouldn't mind I'd like to see an example.

You really should read a tutorial on classes to get an idea of cunstructors.

Code:

#include <iostream>

using namespace std;

class SpaceShip{
  public: 
    int XCoord;
    int YCoord;
    SpaceShip(int x, int y);
};

SpaceShip::SpaceShip(int x, int y){
  XCoord = x;
  YCoord = y;
}

int main(int argc, char* argv[])
{
  SpaceShip ThisSpaceShip(20, 30);
  cout<<"X Coordinate: "<<ThisSpaceShip.XCoord<<endl<<"Y Coordinate: "<<ThisSpaceShip.YCoord<<endl;
  return 0;
}

Regarding your question on std::array...
Click here if you don't know what std::array is (requires TR1 or C++11).

Code:

#include <array>
#include <iostream>

void foo(std::array<int, 5> arr)
{
	arr[0] = 5;
}

int main()
{
	std::array<int, 5> arr = { 1, 2, 3, 4, 5 }; // Requires C++11 initializer lists*
	foo(arr);
	std::cout << arr[0] << std::endl; // Prints 1 because a copy of arr was passed to foo.
}

Code:

#include <array>
#include <iostream>

void foo(std::array<int, 5>& arr)
{
	arr[0] = 5;
}

int main()
{
	std::array<int, 5> arr = { 1, 2, 3, 4, 5 }; // Requires C++11 initializer lists*
	foo(arr);
	std::cout << arr[0] << std::endl; // Prints 5 because a reference of arr was passed to foo.
}
