I think in this case e1.name is initialized by garbage values, e1.age/salary initialized by 0.
So, we can not modify any one of them, but by using strcpy function we can modify e1.name indirectly by using a pointer and this is valid.
strcpy function :
char* strcpy(char* destination, const char* source);
