Pointers in C - GeeksforGeeks
A void pointer can point to variables of any data type but must be typecast before dereferencing. It is commonly used in generic functions and memory management routines where the data type is not known in advance. ... The wild pointer is a pointer that has been declared but not initialized with a valid memory address. Using a wild pointer results in undefined behavior. Dereferencing a wild pointer can cause program ...

ELI5: C pointers: how to use them, and why
They're also very useful to manipulate arrays. In c, if you say int a[], a is a pointer.
So if you do
int a[] = {0,3,2};
printf ("a[1]: %d", *(a+1));
You'll get "a[1]: 3" as the output. Very useful in many cases when trying to optimize for speed.

November 17, 2016ELI5: What are pointers in C? They are really confusing!
Pointers literally point to a location in memory. For comparison: Imagine variables as a box. When you assign to them, like a = 5; you are putting the value of 5 in the box. Similarly, when you use them, like printf("%d", a); you are just looking in the box to see what is inside. Pointers, instead, are like mailbox numbers. They don't store values like integers or characters or strings themselves, they just tell you where to look to find the container that actually stores the value. This is useful because sometimes multiple different locations in code want to modify the same number. So what you do is you pass around the pointer (the thing that points to the box to use), and everyone can edit whatever is at the pointer, and everyone else sees that change. More on reddit.com

Pointers can be declared like any other variables, but two special operators are used to manipulate memory addresses. Using * before a pointer means "the value store at" whereas using & on any variable means "the address of" as is demonstrated in the following example: In line 01 we declare an integer pointer named p, this is only a declaration and this pointer is not "pointing" at any specific area of memory.
