struct MyStruct {
    int age;
    char name[12];
};

 
int main(int argc, char* argv[])
{
    MyStruct tony;
    {
        memset(&tony, 0, sizeof(MyStruct));

        tony.age = 123;
        strcpy(tony.name, "tony");
    }


    MyStruct* pTony = &tony;
    showMemoryHex((void*)pTony, sizeof(MyStruct));
    getchar();
    return 0;
}
