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} };
Variables declared using the string data type usually are initialized to the empty string?
Yes.
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]);
Which one of the following statements allocates enough space to hold an array of 10 integers that are initialized to 0?
int *ptr = (int *) calloc(10,sizeof(int));
Can array be initialized if they are static?
Yes.

How do you make source codes of of declaring an array of type double values?
It declares an array of type double, it has size of 10, and all elements are initialized to 0;...int myArraySize = 10;double myArray[myArraySize] = {0.0}...

How is a10-element char array declared?
char myCharArray[10];

How do you declare a string array and add elements to it in C plus plus?
You cannot add elements to a fixed array in C or C++. If, however, the array is declared as a pointer to an array, you can add elements by allocating a new array, copying/adding elements as needed, reassigning the new array to the pointer, and deallocating the original array.
Write an expression that computes the sum of two variables in java?
int sum = a + b; PS: a and b are int variables that must have been already declared and initialized.
How do you declared and initialized a pointer variable?
#include<iostream> int main() { int x=42; int* p=&x; // declare and initialise a pointer, assigning the address of x. }
