The declaration and initialization declares a pointer array and make it point to a constant array of 31 characters. The declaration and initialization declares an array of characters, containing 31 characters. And yes, the size of the arrays is 31, as it includes the terminating ‘\0’ character. Laid out in memory, it will be something like this for the … Read more
You have declared an array that can store 8 elements not 9. It means postStatus will contain 8 elements from index 0 to 7.
I am trying to merge arrays like this: If: Then the result should be: what I do is that extract histogram of array and merge it with normal array. and maybe that cause the error like this ValueError: operands could not be broadcast together with shapes (5,) (30,) please help me. I don’t know what … Read more
You have the wrong mental model for using NumPy efficiently. NumPy arrays are stored in contiguous blocks of memory. If you want to add rows or columns to an existing array, the entire array needs to be copied to a new block of memory, creating gaps for the new elements to be stored. This is … Read more
Your first port of call should be the documentation which explains it reasonably clearly: Thrown to indicate that an array has been accessed with an illegal index. The index is either negative or greater than or equal to the size of the array. So for example: As for how to avoid it… um, don’t do … Read more
Executive summary: Full answer: To determine the size of your array in bytes, you can use the sizeof operator: On my computer, ints are 4 bytes long, so n is 68. To determine the number of elements in the array, we can divide the total size of the array by the size of the array … Read more
You may have a NAN, INF, or NINF floating around somewhere. Try this: If one or both of those returns False, that’s likely the cause of the runtime error.
You’re getting the error message because you’re trying to set an array element with a sequence. I’m not trying to be cute, there — the error message is trying to tell you exactly what the problem is. Don’t think of it as a cryptic error, it’s simply a phrase. What line is giving the problem? … Read more
In this case, your array variable arr can actually also be treated as a pointer to the beginning of your array’s block in memory, by an implicit conversion. This syntax that you’re using: Is kind of just syntactic sugar. You could really replace it with this and it would still work: So in the same … Read more
How does passing a statically allocated array by reference work? Does (&myArray)[100] have any meaning or its just a syntax to pass any array by reference? I don’t understand separate parenthesis followed by big brackets here. Thanks.
