How can a PHP static be initialized?
PHP static can only be initialized using a literal or constant. You can not use an expression. You can initialize it to an integer but you may not to another variable.
What happen when static data field is initialised in a non static constructor?
It got initialized as you instructed.
Which variable is initialized once when program is compiled?
global and static
How the array has to be declared and initialized?
An example might help int myarray [] = {2,0,1,3,1,1,2,9};
In Java can Array be extended after it has been initialized?
In Java, arrays have a fixed size once they are initialized and cannot be extended. If you need a resizable array, you can use the ArrayList class from the Java Collections Framework, which allows for dynamic resizing. Alternatively, you can create a new array with a larger size and copy the elements from the original array to the new one if you want to extend an existing array.
How do you initialise a two dimentional array?
C provides rectangular multidimensional arrays. In C, a two-dimensional array is really a one-dimensional array, each of whose elements is an array. An array is initialized by a list of initializations in braces; each row of a two-dimensional array is initialized by a corresponding sub-list. Example of two dimensional array initialization: char array_example[2][4] = { {11, 12, 13, 14}, {21, 22, 23, 24} };
Are C variables initialized to 0 by default?
Only global/static variables are, local variables aren't.
Static method can use only static variable why?
A static method is a method that is a class method and is not attached to the object of that class. So if we use a non static variable of the class, it would most probably not have been initialized because no object could have been created for the class. Hence it would throw a null pointer exception. To avoid such an ambiguity, there is a restriction that static methods can use only static variables. This is to ensure that class methods can access only class variables both of which would get initialized simultaneously.
How jagged array can be initialized using indexer?
A jagged array, which is an array of arrays, can be initialized using indexers in C# by first declaring the array and then specifying the size of each sub-array. For example, you can create a jagged array like this: int[][] jaggedArray = new int[3][];, and then initialize each sub-array individually, such as jaggedArray[0] = new int[2]; and jaggedArray[1] = new int[3];. You can also initialize it inline, like int[][] jaggedArray = new int[][] { new int[2], new int[3], new int[1] };. This allows for flexible sizing of each inner array.
How do you get the middle number for the turbo c using array?
it depends how you have coded your program as: if you initialized your array (a) by loop from 0 then int lb=0,ub=n-1; //n is number of elements in array int mid=(lb+ub)/2; printf("middle number is :%d",a[mid]); if you initialized your array (a) by loop from 1 then int lb=1,ub=n; //n is number of elements in array int mid=(lb+ub)/2; printf("middle number is :%d",a[mid]);
Can static variables be changed?
No, a static variable means that there is only one copy of that variable, and it is shared by all members of the class, or by all callers of a function.A variable that is read-only would be marked as const or final (depending on language).
What is the difference between queues and circular queues?
A queue can use a dynamic array, or a linked list, but if using static memory, the queue becomes a circular queue because the underlaying data structure is a static circular array. This means the ends of the array are attached.
