WebA primitive int obviously takes 4 byte. An Integer object has an overhead of about 24 byte (this is implementation specific) plus 4 byte for the data, so about 28 byte. An array is an object which also has an overhead of 24 bytes plus 4 bytes for the length plus data. An int [] array thus uses 28 bytes plus 4 bytes for each int. WebJun 16, 2024 · The number of elements is what you have in the array definition, so myInt as 5 elements of type int which each take 2 bytes on a uno. So you will have 10 bytes for this array. If you were to skip the 5 and let the compiler decide, it would be 4 int so 8 bytes Same rule for the char array, you will have 25 bytes

WebFeb 4, 2013 · C Pointer Basics Question 4. Consider a compiler where int takes 4 bytes, char takes 1 byte and pointer takes 4 bytes. Explanation: Size of an array is number of elements multiplied by the type of element, that is why we get sizeof arri as 12 and sizeof arrc as 3. Size of a pointer is fixed for a compiler. WebMay 20, 2024 · An empty list takes 56 bytes, but each additional int adds just 8 bytes, where the size of an int is 28 bytes. A list that contains a long string takes just 64 bytes. The answer is simple. The list doesn't contain the int objects themselves. It just contains an 8-byte (on 64-bit versions of CPython) pointer to the actual int object.
