So i contains an address, and at that memory address, C is expecting to see another pointer. That second memory address, then, is expected to hold an int. Do note that, while you are declaring a pointer to an int, the actual int is not allocated.

WebFeb 20, 2015 · 23. In C++, there are two types of storage: stack -based memory, and heap -based memory. The size of an object in stack-based memory must be static (i.e. not changing), and therefore must be known at compile time. That means you can do this: int array [10]; // fine, size of array known to be 10 at compile time. WebThe first part (sizeof (a) / sizeof (* (a))) is fairly straightforward; it's dividing the size of the entire array (assuming you pass the macro an object of array type, and not a pointer), by the size of the first element. This gives the number of elements in the array. The second part is not so straightforward.

WebApr 10, 2024 · So, 3 may be an int, but, in order to match the definition of the overload, it will first be converted to std::vector::size_type. In other words, with the C++ standard container types, you are effectively always using size_t for the indexes, regardless of what type you actually use.

Saying the size of char isn't specified explicitly is misleading. sizeof (char) is 1 by definition (so a char is a byte). ctc27w24ei bosch fridge
