Insert an element after an element in an array?
To begin, obtain the element to be added, such as x Then, say pos, get the position where this element will be put. Then shift the array items one position ahead, then do the same for all the other elements next to pos. Because the location pos is now empty, insert the element x there.

Program to insert an element in array at beginning?
Answer: Use the unshift() Method You can use the unshift() method to easily add new elements or values at the beginning of an array in JavaScript. This method is a counterpart of the push() method, which adds the elements at the end of an array. However, both method returns the new length of the array To learn more about data science please visit- Learnbay.co
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.
What are two possible remedies for a disk subsystem that is the bottleneck in a servers performance?
ANSWER Any two of the following: ■ Install faster hard disk drives. ■ Install additional hard disk drives and split your data among them, reducing the I/O burden on each drive. ■ Replace standalone drives with a RAID (redundant array of independent disks) array. ■ Add more disk drives to an existing RAID array.
Write a program to input a string in the form of name and swap the initials of the namefor example enter a string is rohit Kumar sharma and should be printed RK Sharma?
Get the string from user , then U Split the string with space and put in a string array .Then Find Length of string array , Take first letter of each element in array, Except last. Assigned those to a string, then Fetch Last element of an array, Add it With that String.That's it.
How can you add a new element in an ordered vector in the right position in c language?
Use insertion sort. First, add a new element to the end of the array. The value of this new element does not matter at this stage, all we are really doing is creating a place-holder. We now look at the element to the left of the place-holder and, if it is greater than the value we are inserting, we copy that element's value to our place-holder, effectively moving it one element to the right and moving our place-holder one element to the left. We continue in this manner until the element to the left of the place-holder is not greater than the value we are inserting, or the place-holder reaches the beginning of the array. We then copy our new value into the place-holder. In effect, the place-holder creates a "gap" in the array and we simply move that gap to the left until it finds its correct place according to the value we are inserting. The algorithm works even when there are not (yet) any elements in the array. Note that if the last element of the array is not greater than the new value, the gap does not move (the new value has found its place at the end of the array). Note also that elements of equal value are kept in stable order (in the same order they were input).
Program in c plus plus to delete an element in sorted array?
If the array is dynamic then use a vector instead of an array. You can then use the vector::erase() function to delete an element or a range of elements. Remember that if the vector contains pointers to unshared memory, then you must release the pointer before erasing the element containing that pointer. If the array is static then you cannot delete elements. The assumption with static arrays is that you will neither add nor delete, you will only modify existing elements. However, you can emulate a deletion by shunting elements to the left, and keeping track of how many used elements there are (which must always be less than or equal to the upper bound plus one). Again, if the array contains pointers to unshared memory, you must release the pointer before shunting elements. You can also do the same thing with dynamic C-style arrays, but once you've shunted elements to the left you can reallocate the array with the new size to physically delete the final element.
What is the differnce between linked list and arrays?
A linked list is a series of elements, each containing a pointer or index to the next element in the list. You can dynamically add and delete elements in the list. An array is a contiguous block of repeated elements. Since each element is address-wise adjacent to the next element, there is no need for pointers or indexes to the "next" element. You can not dynamically add and delete elements in an array, although you can create "dynamic arrays" with (templates and) classes that auto-resize themselves. The STL does this for you, but it is a good exercise to implement it yourself.
How are elements of an array stored in memory?
Computer memory is linear so a one dimensional array can be mapped on to the memory cells in rather straight forward manner.To find the actual address of an element one needs to subtract one from the position of the desired entry and then add the result to the address of the the first cell in the sequence.Having said that therefore it is necessary to know the starting address of the space allocated to the array and the size of the each element, which is same for all the elements of an array.The the location of the Ith element would be B+I*S where B is the base address(Starting address of the array) and S is the size of each element of the array.
What complications are imposed if one tries to implement a dynamic list using a traditional homogeneous array?
in dynamic list after adding a new element size of the list disturbed so deletion and insertation is necessary to add a new element
Describe the advantages and disadvantages of array in data structure?
Array Pros:can access any element of an array directlycan be used to create other useful data structures (queues, stacks)light on memory usage compared to other structuresArray Cons:rigid structurecan be hard to add/remove elementscannot be dynamically resized in most languages
