How can I store the content of a pointer into a variable?

Question

I was just wondering how I should go about storing the content of a pointer into a variable, particularly something along the lines of:

somethingpoint = getenv(somethingsomething);

This pointer would refer to a string .

Answer 1

You need to declare a pointer variable, and then assign to it. You can do this all in one line of code, like this:

const char *value = getenv(name);

I'm using const here because getenv returns a pointer to a string whose contents must not be modified by the program. Using const lets the compiler help us honour that contract.

Answer 2

const char* test = getenv(pointerName);
