Difference between a struct and a class

• Longstructs can implement interfaces and can have the same kinds of members as classes.
• structs are value types rather than reference types,
• Inheritance is not supported for structs.
• Struct values are stored on the stack or in-line.
• Careful programmers can sometimes enhance performance through judicious use of structs. For example, the use of a struct rather than a class for a Point can make a large difference in the number of memory allocations performed at runtime.
