- c++ - Why is arr and arr the same? - Stack Overflow
I know that arr[0] and arr evaluates to the same number, but that is not my question! The question is why arr and arr evaluates to the same number If arr is a literal (not stored anyware), then the compiler should complain and say that arr is not an lvalue If the address of the arr is stored somewhere then arr should give me the address of
- 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
var arr = [[1,2], [3,4], [5,6]]; for (var i=0; i < arr length; i++) { i = 0, then we loop below: for (var j=0; j < arr[i] length; j++) { here we loop through the array which is in the main array in the first case, i = 0, j = 1, then we loop again, i = 0, j = 1 console log(arr[i][j]); after we finish the stuff in the 'j' loop we go back
- What is the difference between * arr and * arr[0] in C++, if arr is an . . .
Just like arr, this array lvalue decays to a pointer to first element when converted to an rvalue Except for cases where the operators are overloaded, * essentially cancel each other out They are inverse operations * arr[0] gives you the same as arr[0] and * arr gives you the same as arr
- What is the meaning of arr [:] in assignment in numpy?
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 values of arr2 will be broadcasted and copied as needed arr=arr2 sets the object that the arr variable is pointing to Now arr and arr2 point to the same thing (whether array, list or
- sorting - Selection Sort algorithm - Stack Overflow
print(selectionSort(arr)) How Selection sort works? Starting from the first element, we search the smallest element in the array, and replace it with the element in the first position
- What does arrays. length -1 mean in Java? - Stack Overflow
The reason behind arr length-1 is, we are looping all the elements from i=0 to i=6 as array lenght=8 and i<8-1 means i<7 so it would result in printing only from 0 to 6 So its going to print elements only upto :[23,75,982,22,74,45,0] Code should be changed from i<arr length-1 to i<arr length and you will print all values
- c - Difference between *arr [] and **arr - Stack Overflow
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
