What is the output of the following code fragment? The code is assumed to be embedded in a correct and complete
int arraySize = 10;
int *a;
a = new int[arraySize];
int i;
for (i = 0; i < arraySize; i++)
* (a + i) = i;
for (i = 0; i < arraySize; i++)
cout << a[i] << “ ”;
cout << endl;

In java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. (ONLY ARRAYS or ARRAYLIST)
Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated.
Develop a function that returns true if the elements are in decreasing order and false otherwise.
A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks.
Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8,…
Write a function that gets an array as a parameter (address and size) and a number and checks to see if that number exists in the array. The function should report every single occurrence of the number in the array. It should also report how many occurrences were detected in total (use c code)Suggested prototype:
void findnReport(int* ar, int size, int num)
Example of function output:
If array = {2,5,3,5,12,13,14,15,0,5,-1,11,5} and num = 5,
Number 5 found in array index 1
Number 5 found in array index 3
Number 5 found in array index 9
Number 5 found in array index 12
Total of 4 occurrences of number 5
In java there must be at least two calls to the function with different arguments and
the output must clearly show the task being performed.
1. Develop a function that accepts an array and returns true if the array contains any
duplicate values or false if none of the values are repeated.
2. Develop a function that returns true if the elements are in decreasing order and
false otherwise.
3. A "peak" is a value in an array that is preceded and followed by a strictly lower
value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks.
Develop a function that returns the number of peaks in an array of integers. Note that
the first element does not have a preceding element and the last element is not
followed by anything, so neither the first nor last elements can be peaks.
