Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Create a function named Sum that accepts the array pointer and the size of the array Expected Output: Please Enter the Size of an Array : 7 Please Enter Array Elements : 10 20 200 30 500 40 50 Sum of Elements in this Array = 850
Write a C function and program that calculates the array size after deleting a certain element of a 10-element integer array from the array. Sample: Series: 1 2 2 3 4 4 5 5 6 6 Array size after 4 deleted: 8 Note: A CALL BY REFERENCE function will be written. The element we want to delete will be entered by the user.

Write a C Program for this question Write a function called mergeArrays. It should accept three integer arrays: A, B and C, and two integers m and n representing the sizes of the first two arrays. It can be assumed that the size of C is m+n. Arrays A and B contains integers that are already sorted in the ascending order (i.e. increasing order). Your function must combine all the numbers in A and B and store them C in such a way that C is also sorted in the ascending order. Here is an example to clarify the requirements. In this case, the sizes of A and B are 6 and 4 respectively. SAMPLE A : 0 4 5 5 7 9 B: -1 0 3 6 C: -1 0 0 3 4 5 5 6 7 9 Then you have to separate odd and even integers in two separate arrays respectively.
Write a function IsPalindrome() that takes an array of characters called Items and an integer called size as parameters. Thelatter indicates the size of the array.
