Final conclusion: arithmetic on a void* is illegal in both C and C++. GCC allows it as an extension, seeArithmetic on void- and Function-Pointers(note that this section is part of the "C Extensions" chapter of the manual). Clang and ICC likely allow void* arithmetic for the purposes of...
Therefore void pointers must be first typecast to a known type before they can be involved in any pointer arithmetic. void *p = malloc(sizeof(char)*10); p++; //compiler does how many where to pint the pointer after this increment operation char * c = (char *)p; c++; // compiler ...
Arithmetic Operators in C: The Arithmetic Operators in C allow you to construct various formulas and mathematical equations. These are of two types- binary and unary. Visit to know more about Arithmetic Operators in C.
are pointers past the end of the last element of x if i + j is n. The expression P - J points to the i-jth element of x if i - j is in [0, n), and is a pointer past the end of the last element of x if i - j is n. Other j values result in undefined...

The return stack, however, holds any number of “pointers” which the Forth system uses to make its merry way through the maze of words that are executing other words. We’ll elaborate later on. You, the user, can employ the return stack as as kind of “extra hand” to hold values ...
V724. Converting integers or pointers to BOOL can lead to a loss of high-order bits. Non-zero value can become 'FALSE'. V725. Dangerous cast of 'this' to 'void*' type in the 'Base' class, as it is followed by a subsequent cast to 'Class' type. V726. Attempt to free memory ...

One of Zig's fundamental beliefs is that allocation can fail, even though allocation succeeds 99.9999% of the time (made up statistic but probably pretty close). Zig would be faster if it didn't check whether allocation failed and didn't pass around allocator pointers. But would it be ...
Currently adding to pointers doesn't work: stdin:1:37-38: ERROR: The + operator can not be used on expressions of types cast, integer BEGIN { $a = (uint16*) 123; $b = $a + 5; } In C adding to a pointer uses the pointee size to increment, so: ...
