Programming in C

Pointers

A variable that points to an address in memory.

Basics

Pointers can be initialized outright or created for an existing variable.

char var1 = "Hello";
pointer1 = *var1;

char *pointer2 = "Hello"

Then, the following will print the same output:

printf("%s", var1);
printf("%s", pointer1);
printf("%s", pointer2);

Pointers in C++

Since memory is deleted at the end of an objects life, you need to be careful passing values to pointers in C++.
