You cannot store arrays in a vector or any other container. The type of the elements to be stored in a container (called the container’s value type) must be both copy constructible and assignable. Arrays are neither. You can, however, use an array class template, like the one provided by Boost, TR1, and C++0x: (You’ll … Read more
Actually, when you have an array a[SIZE], you can always check: But it’s not necessary, unless you created a dynamic array (using operator new). See the other answers, I won’t delete it just because it’s accepted now. If other answer is accepted, I’ll delete this “answer”. EDIT (almost 4 years later 🙂 ) As I … Read more
Cannot use object of type mysqli_result as array Use mysqli_fetch_assoc or mysqli_fetch_array to fetch a result row as an associative array. or
See my answer about spatial and temporal locality. In particular, arrays are contiguous memory blocks, so large chunks of them will be loaded into the cache upon first access. This makes it comparatively quick to access future elements of the array. Linked lists on the other hand aren’t necessarily in contiguous blocks of memory, and could … Read more
I am completely stumped. I took a break for a few hours and I can’t seem to figure this one out. It’s upsetting! I know that I need to check the current element in the array and see if it appears elsewhere in the array. The idea is to output the following: The user is … Read more
Assuming your array is {10,20,30,40,50,60,70,80,90,100} What your loop does is: Iteration 1: array[1] = array[0]; {10,10,30,40,50,60,70,80,90,100} Iteration 2: array[2] = array[1]; {10,10,10,40,50,60,70,80,90,100} What you should be doing is
I am trying to get a deeper understanding to how for loops for different data types in Python. The simplest way of using a for loop an iterating over an array is as I also know that I can What I would like to know is what this does or And what happens if I … Read more
You could sort the array and then run through it and then see if the next (or previous) index is the same as the current. Assuming your sort algorithm is good, this should be less than O(n2): Expand snippet In case, if you are to return as a function for duplicates. This is for similar … Read more
Everything in a Java program not explicitly set to something by the programmer, is initialized to a zero value. For references (anything that holds an object) that is null. For int/short/byte/long that is a 0. For float/double that is a 0.0 For booleans that is a false. For char that is the null character ‘\u0000’ (whose decimal equivalent is 0). When … Read more
