Question

Can anyone help me in the following question please?

Define a macro which has the following prototype:

F(A, B, C, D)

After using this macro as F(name, float, a, b), you should be able to use the variables name.a and name.b. Make sure that your implementation is reusable, i.e you can use F more than once in the same block.

Also, extend it so that a predefined prefix is added to the variable. That is, if the predefined prefix is pt, then after using this macro, you should be able to use
pt_name.a, and pt_name.b.

Here:

#define F(name, type, var1, var2) struct {\
                                     type var1 ;\
                                     type var2 ;\
                                  } name

That should work.
