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. Tamper Evident Pro...

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 ...
Why can't you just use an integer in the examples above instead of a pointer to an integer? Well, the above is clearly a contrived example. The real power of pointers is that, in conjunction with records, it makes dynamically-sized data structures possible. If you need to store many ...
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 ...

Two pointers which both refer to a single object are said to besharing. That two or more entities can cooperatively share a single memory structure is a key advantage of pointers in all computer languages. Pointer manipulation is just technique but the sharing itself is often one of the premie...

//printing the value of the structure pointer printf("ptr = %p\n", ptr);return 0;} Output: ptr = 0x7ffd316f46e4 Function Pointer These pointers point to functions rather than some data type like int, char, etc. We cannot allocate or deallocate memory in the case of function pointers...
