I think it's worth mentioning how powerful the cast operator can be. And
the
fact that it can be used for ANY data type.
Let's look at an example.
Let's say you've got 2 structures:
struct struct1 {
char player_name[20];
float score;
};
struct struct2 {
char character_name[20];
int strength;
int wisdom;
};
Then, in your code, you can perform tests on pointers to memory by just
using the cast operator.
...
int wis;
wis = ((struct struct2)ptr)->wisdom;
...
or something like that, anyway.
