Although C doesn't have the notion of class as in object-oriented languages, it does have the structure, which allows you to define a new data type representing a conglomeration of data. The primary distinction between a class and a structure is that a class can have both variables and ...
These are the pointers that point to the address of a structure, a user-defined data type. With the help of structure pointers, complexdata structureslike linked lists, trees, graphs, etc., are created. The syntax of a structure pointer in C is as follows: struct struct_name *ptr; The ...

We should Note that the hash stored in the hash pointer is the hash of the whole data of the previous block, which also includes the hash pointer to the block before that one. This makes it’s impossible to tamper a block in the blockchain without letting others know. ...
s capabilities – the address of a particular memory location must be assigned to the pointer.It is possible to assign address of single variable or that of an array or the address of a structure etc to a pointer variable.This capability makes pointers the most powerful tool in C programming...
You can use the fixed keyword to create a buffer with a fixed-size array in a data structure. Fixed-size buffers are useful when you write methods that interoperate with data sources from other languages or platforms. The fixed-size buffer can take any attributes or modifiers that are ...
an array of pointers is a data structure in which the elements of the array are pointers. instead of holding data directly, each element in the array holds the memory address (pointer) of another data element. this allows for the creation of an array where each element can point to a ...
I ran into a clever trick while reading the solutions here https://codeforces.com/blog/entry/133382 (look at problem 2006C, "Implementation — Two Pointers") The problem is: let's say there's an array aa and an associative operation ∗∗ and we are interested in computing f(l,r):...
