It is not considered an overload in the following cases:

1. Functions with different return values cannot be considered overloaded

2. Whether the return value is static cannot be considered overloaded

3. Arrays and pointers

int fun( int *ptr); int fun( int ptr[]); // redeclaration of fun(int *ptr) 4, functions, and function pointers void h( int ()); void h( int (*)()); // redeclaration of h(int()) 5, whether the parameter is const cannot be distinguished (but is possible for class member functions) Note: The const modifier pointer parameter or reference parameter can be used as an overloaded identity, so to understand, because the pointer or reference as a formal parameter can modify the argument itself, when the Const modifier refers to the content cannot be modified, so can be used as a distinguishing overload of the identity http:/ www.geeksforgeeks.org/function-overloading-and-const-functions/ 6, whether default parameters cannot be distinguished
