Go pointer to struct Pointers are often used with structures in Go. pstruct.go package main import "fmt" type User struct { name string occupation string } func modify(pu *User) { pu.name = "Robert Roe" pu.occupation = "driver" ...
Here, an incomplete struct is used as if it is a complete struct, which causes the compiler to throw the error. 1035906452/source.c: In function 'main':1035906452/source.c:6:5: error: dereferencing pointer to incomplete type 'struct round'*x;^~ ...

Comparison operatorsare defined for pointers to objects in some situations: two pointers that represent the same address compare equal, two null pointer values compare equal, pointers to elements of the same array compare the same as the array indices of those elements, and pointers to struct memb...
