Size of Pointers in C with code The size of the Pointers is not fixed and it is independent of data type. It depends on the size of the different factors such as CPU architecture and the word size of the processor. Determining the size of a pointer is required if you want to know ho...
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 ...
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 ...

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 ...

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. ...

They are often used in C/C++ data structure implementations to allow those data structures to store data of many different types without needing to change the underlying source code of the data structure for each type.In order to use a void pointer (e.g. one returned by a function), you...
