typedef's have the advantage that they obey scope rules, that is they can be declared local to a function or a block whereas #define's always have a global effect.

For eg.,
{
typedef char c;
c c1;//c is char
{
typedef int c;
c d1;//c is int
}
}
But #define always has global scope till the end of the file.

#define function used in globally. We can access that data in the program any where.
