  2. Are the arrays constant? If so, one possibility is to use two separate initialized constant arrays, and then set a pointer (to constant data) to point to the relevant array. You would also make the arrays static. If the arrays are not constant, then I believe you are stuck with calculating each element in turn. –

  3. size_t n = sizeof(a)/sizeof(a[0]); Full answer: To determine the size of your array in bytes, you can use the sizeof operator: int a[17]; size_t n = sizeof(a); 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 element.

    char *array = "One good thing about music"; declares a pointer array and make it point to a (read-only) array of 27 characters, including the terminating null-character. The declaration and initialization. char array[] = "One, good, thing, about, music"; declares an array of characters, containing 31 characters.

  5. Passing an array as an argument to a function in C

    stackoverflow.com/questions/6567742

    Arrays in C are converted, in most of the cases, to a pointer to the first element of the array itself. And more in detail arrays passed into functions are always converted into pointers. Here a quote from K&R2nd: When an array name is passed to a function, what is passed is the location of the initial element.

  6. Returning an array using C - Stack Overflow

    C's treatment of arrays is very different from Java's, and you'll have to adjust your thinking accordingly. . Arrays in C are not first class objects (that is, an array expression does not retain its "array-ness" in most con

    OP is using C, C allows padding bits, which can cause an incorrect memcmp result. Since OP didn't specify that he is using a platform without padding bits, but posted the question in relation to the C Programming language. See title and tag. (Please use @ or I won't be reading your responses. ) –

  9. int[] z = (from arrays in new[] { a, b, c } from arr in arrays select arr).ToArray(); Although the latter method is much more elegant, the former one is definitely better for performance. For additional info, please refer to this post on my blog.

  10. If you want a method that always works, then store the initial size of the array in an int size = 0; variable and increase it every time you append a new element: array[size++] = ... int array[5]; int size = 0; // you can set the size variable larger. // if there are already elements in the array.

    No, this is what we call a matrix. In my book, the function "dijkstra" gets an unidimensional array as an argument, "Adj []", which is a list of adjacency lists. This is how they manipulate it, in pseudocode: "int u = [some_number]; int v; for each v in Adj [u] do ..." Where Adj [u] is supposed to be the adjacency list of the vertex 'u', and ...
