First steps in C++

• All data types (except arrays)
  • Passing by Value: default

    
    void SomeFunc(float x)
    {
    ...
    }
    

  • Passing by Reference: Put an ampersand (&) after the name of the data type

    
    void SomeFunc(float& A)
    {
    ...
    }
    

• ARRAYS:
  • Passing by value is NOT possible. To prevent the function from modifying the caller's array begin the formal parameter declaration with the keyword const

    void SomeFunc(const float vec[])
    {
    ...
    }
    

  • Passing by reference: Default

    void SomeFunc(float vec[])
    {
    ...
    }
