Exercise 6.39

Explain the effect of the second declaration in each of the following sets of declarations. Indicate which, if any, are legal.

(a)

int calc(int, int);
int calc(const int, const int);

(b)

int get();
double get();

(c)

int *reset(int *);
double *reset(double *);

Solution

(a) declares the same function twice, legally. (b)'s second definition will be in error as only the return types differ. (c) will acceptably declare both functions, legally.
