The video tutorial explains operator overloading in C, emphasizing that the basic behavior of operators should remain unchanged when overloaded. It highlights special cases like the 'new' and 'delete' operators, which are overloaded under specific circumstances. The tutorial outlines rules for overloading, such as requiring one operand to be a user-defined type and the need for global functions when the first argument is a primitive type. It also lists operators that cannot be overloaded due to potential confusion or disruption of basic features. Finally, it stresses the importance of maintaining conventional behavior to avoid user confusion.
