constutor in struct c++ code example
Example 1: constructor c++ struct
struct Rectangle {
int width; // member variable
int height; // member variable
// C++ constructors
Rectangle()
{
width = 1;
height = 1;
}
Rectangle( int width_ )
{
width = width_;
height = width_ ;
}
Rectangle( int width_ , int height_ )
{
width = width_;
height = height_;
}
// ...
};
Example 2: function in struct c++
struct foo {
int bar;
foo() : bar(3) {} //look, a constructor
int getBar()
{
return bar;
}
};
foo f;
int y = f.getBar(); // y is 3
