The first code is an example of Javascript code, which is similar, however not JSON. JSON would not have 1) comments and 2) the var keyword You don’t have any comments in your JSON, but you should remove the var and start like this: The [{}] notation means “object in an array” and is not … Read more
It’s a dynamic array. Practical proof: Indexing takes (of course with extremely small differences (0.0013 µsecs!)) the same time regardless of index: I would be astounded if IronPython or Jython used linked lists – they would ruin the performance of many many widely-used libraries built on the assumption that lists are dynamic arrays
How do I find the size of a 2D array in C++? Is there any predefined function like sizeof to determine the size of the array? Also, can anyone tell me how to detect an error in the getvalue method for arrays while trying to get a value which is not set?
First, myArray == &myArray == &myArray[0] is not going to do what you expect. Second, &myArray is of type int (*)[10] while myArray and &myArray[0] are of type int *. Both types are incompatible with each other.
Your code as it stands is correct but I am having a hard time figuring out how it could/would be used in a real world scenario. With that said, please be aware of a few caveats when returning pointers from functions: When you create an array with syntax int arr[5];, it’s allocated on the stack … Read more
There are several flavors of arrays, depending on how and where they are declared. Fixed-length Arrays Fixed-length arrays must have their size determined at compile time. You cannot change the size of a fixed-length array after it has been defined. Fixed-length arrays are declared in one of the following ways: In the first three cases, … Read more
I don’t understand the problem you have since an ArrayList implements a List with List being an interface. You can change this line to:
Yes char arrays are not assignable just as all arrays aren’t. You should use strcpy for example and so on. Also, you don’t need to declare char class[30]; the longest string I see in your code is “undefined” so should be ok, 9 characters of “undefined” + 1 null terminating byte ‘\0’. And you should … Read more
Let’s say I have an array of four objects: Is there a way that I can get the third object ({a: 5, b: 6}) by the value of the property b for example without a for…in loop?
