Hello, I miss some bases in c++ and a thing would help me is to be able to create operator to do some operation between custom variables.
For example:
struct quote
{
  float number;
  int coeff;
}
quote var1, var2;
...
quote result=var1+var2;

Open in new window

to have the "+" multiply the number and coeff before adding the to product.

Thanks
