"Why is Function overloading not possible with different return types?

Function overloading comes under the compile-time polymorphism. During compilation, the function signature is checked. So, functions can be overloaded, if the signatures are not the same. The return type of a function has no effect on function overloading, therefore the same function signature with different return type will not be overloaded."
