Is it possible to overload operators in C?

C does not support overloading of operators or functions. There's no way you can redefine <, <=, >, >=, ==, or != to compare struct types directly.

No, it is not possible. C does not support operator overloading by the developer.

If by overload, you mean user defined operator overloads, then the answer is no. However, some of the predefined operators such as *, + etc. are overloaded (if you think about it) for arithmetic types. The * is special since it also has an overload for de-referencing pointers.
