Few rules about C pointers 1) A pointer variable does not store value directly just like int, float variables. A pointer store only reference (memory address) of another variable.Consider the following codeint x=100; int *ptr; ptr = &x; Here x is a simple int variable, the current ...
The definition for "object type" is: 6.2.5.1: Types are partitioned into object types (types that fully describe objects) , function types (types that describe functions), and incomplete types (types that describe objects but lack information needed to determine their sizes). And the standard ...
An example of definition could be : const int* ptr; Lets take a small code to illustrate a pointer to a constant : #include<stdio.h> int main(void) { int var1 = 0; const int* ptr = &var1; *ptr = 1; printf("%d\n", *ptr); ...
So, the question here is whether void* is a pointer to an "object type", or equivalently, whether void is an "object type". The definition for "object type" is: 6.2.5.1: Types are partitioned into object types (types that fully describe objects) , function types (types that describe ...
