C++ struct initialization assertion fails

Question

#include <cassert>
#include <string>
struct AStruct 
{ 
    int x; 
    char* y; 
    int z; 
};
int main()
{ 
    AStruct structu = {4, "Hello World"};
    assert(structu.z == ???);
}

What should I write in place of ??? to have a successful assertion?
I used assert(structu.z == 0); but unfortunately got the error
int main(): Assertion 'structu.z == 0 failed.Aborted'

Answer 1

You want:

 assert(structu.z == 0);

Your code assigns to the z member instead of testing it. And if you did get the message your edited question says you did, your compiler is broken. Which one is it?
