Hello, Can someone please tell me what the difference is between the following 2 examples:


ex1:

typedef struct // what does the typedef do for the struct?
{
    int x;
    int y;
} placeName;

ex2:

struct placeName
{
    int x;
    int y;
};

Thanks for any help.

typedef struct is a reminant of C. Assuming you're using C++, they're syntatically equivalent.

In C, you can NOT simply say
placeName variable;
using the 2nd example. C requires
struct placeName variable;
Now if you use the typedef version (ex1), you can say
placeName variable;
and expect it to compile in C.

Using C++, the examples are virtually the same.
