A prvalue of type“pointer to cv T,”whereT is an object type,can be converted to a prvalue of type“pointerto cvvoid”.Theresult of converting a non-null pointer value of a pointer to object type to a“pointer tocvvoid”represents the address of the same byte in memory as the ori...

Void pointeris a specific pointertype-void *- a pointer that points to some data location in storage, which doesn't have any specific type. So, once again,null pointeris avalue, whilevoid pointeris atype. These concepts are totally different and non-comparable....

Square brackets,[], are typically used for array, indexer, or pointer element access. Beginning with C# 12,[]encloses acollection expression. Array access The following example demonstrates how to access array elements: C# int[] fib =newint[10]; fib[0] = fib[1] =1;for(inti =2; i ...
