- c - Difference between *arr [] and **arr - Stack Overflow
Theoretically, *arr[] and **arr are different For example : char *arr[size]; case 1 Here arr is a an array of size size whose elements are of the type char* Whereas, char **arr; case2 Here arr is itself a pointer to the type char* Note: In case 1 array arr degrades to a pointer to become the type char** but it's not possible the other way around i e, pointer in case 2 cannot become an array
- What is the meaning of arr [:] in assignment in numpy?
Your question involves a mix of basic Python syntax, and numpy specific details In many ways it is the same for lists, but not exactly arr[:, 0] returns the 1st column of arr (a view), arr[:,0]=10 sets the values of that column to 10 arr[:] returns arr (alist[:] returns a copy of a list) arr[:]=arr2 performs an inplace replacement; changing the values of arr to the values of arr2 The
- Understanding arr[::-1] in numpy. Is this a special case?
In fact it is just interpreting that it needs to go till the boundary as arr [::1] gives normal array Is this just coded as a special case or is there something more going on?
- How do I determine the size of my array in C? - Stack Overflow
The generated code will be identical, since the compiler knows the type of *int_arr at compile time (and therefore the value of sizeof (*int_arr)) It will be a constant, and the compiler can optimize accordingly

- Array increment positioning with respect to indexer in C - array [i . . .
In this example i = 3, so arr[3] = 40 It then increases the value from 40 to 41 So arr[i]++ increments the value of this particular index and a[i++] first increments the index and then gives the value for this index
- Understanding nested for loops in javascript - Stack Overflow
Got it, so with arr [i] [j] you actually first grab the inner array then the element inside the inner array and print it out, thanks! Your array [0] [0] made it click
- How does *( arr + 1) - arr give the length in elements of array arr?
The trick is to use the expression ( arr) [1] - arr to get the array arr size Both arr and arr points to the same memory location, but they both have different types
