When a string literal is used to initialize an array of char or wchar_t The following examples demonstrate the implicit conversion of array designators into pointers, using the conversion specification %p to print pointer values: #include <stdio.h> int *iPtr = 0; // A pointer to int, init...
The fourth way to initialize the pointer is to use the value zero. Zero is a special values used with pointers, as shown here: p = 0; or: p = NULL; What this does physically is to place a zero into p. The pointer p's address is zero. This is normally diagrammed as: ...

us to create an array whose size can be determined at runtime. We then initialize each struct individually. Finally, we free the allocated memory to prevent memory leaks. This method is particularly useful when dealing with larger datasets or when the number of elements isn’t known beforehand...
