"Internal pointer" sounds interesting. Can you share a link to where you read about it the first time?

Okay, I saw it. But I'm sorry I can't quite explain it cause she speaks rather fast, and I didn't really catch what she meant by saying internal pointer. Don't worry though, someone will light your way eventually ...

Pointer variable is a one kind of variable that points another variable. It points another variable by storing address location of that variable. To declare pointer, you need to use * sign followed by meaningful variable name. Suppose, int a = 10; // variable declaration int *p; // pointer declaration p = &a; // p store the address of a *p = 10 // *p equals to 10, means *p indirectly access a variable value by storing address location of a. In C by default array name acts as a pointer to first element of the array. That may be called as internal pointer.
