- Indicate true or false for the following statements: a. Every element in an array has the same type. b. The array size is fixed after an array reference variable is declared. c. The array size is fixed after it is created. d. The elements in an array must be of a primitive data typearrow_forward- in this exercise, please do not include and use string class. The function is using only array notation and manipulation.- string functions such as strlen is not allowed.- it should not have multiple return statements in the same function- there should be no global variable.- the function should not traverse the arrays more than once (e.g. looping through the array once only) A C++ PROGRAM named "changeCase" that takes an array of characters terminating by NULL character (C-string) and a boolean flag of toUpper. If the toUpper flag is true, it will go through the array and convert all lowercase characters to uppercase. Otherwise, it will convert all uppercase to lowercase. For example, if the array is {'H', 'e', 'l', 'l', 'o', '\0'} and the flag is true, then the array will become{'H', 'E', 'L', 'L', 'O', '\0'}. And if the flag is false, the array will become{'h', 'e', 'l', 'l', 'o', '\0'}arrow_forwardPLEASE DO YOUR OWN CODING NO COPYING Write an assembly program to compute the following expressions - Create a DWORD array named ‘z’ of size 3 using DUP operator. Leave the array ‘z’ uninitialized.You can denote the items in the array as [�!, �", �#], where �! is the first item, �" is the second item,�# is the third item- Update each array item using the following expressions. �! = � + 130�" = � + � − �!�# = � + � − 13 - Where x, y, r are 16-bit integer memory variables.- x = 10, y = 15, r = 4- Use mov, movzx, movsx, add, sub instructions only.- (hint: Do not alter the value of x, y and r during the computation. Transfer them to appropriate registers to docomputation)- At the end, open memory window to see the variable z stored in memory (little endian format).- If you code correctly, �! = 140 in decimal, �" = −115 in decimal, �# = 1 in decimal § Screenshot of the code and memory window showing the content of the variable z (little endianformat).arrow_forward

- 3.use c code to Write a function that gets two same size arrays as parameters and determines if they are permutations of each other. Two arrays are permutations of each other if one can be obtained by shuffling the other. If the arrays are permutations, the function should return 1 otherwise it should return 0. A suggested prototype for that function could be:int isPermutation(int array1[], int array2[], int commonSize) Example: If the two arrays are: Array1: {1,2,4,0, 5} Array2: {0,5,3,2, 1) Function should return a 0. If the ‘3’ in Array2 is changed to ‘’, it should return 1 Hint: answer must use c code and show the outputarrow_forward1-Write a C++ program to input elements in array and sort array elements in descending order. How to sort array in descending order in using pointers.Use function to print out the original and sorted arrays, Example Input Input size of array: 10 Input array elements: 20, 2, 10, 6, 52, 31, 0, 45, 79, 40 Output Array sorted in descending order: 79 ,52,45,40,31,20,10,6,2,0arrow_forward5. Using c++, Write a function that determines the index of the second to the last occurrence of a target b in an integer array a. Return -1 if b is not in a or there is only 1 occurrence of b in a.arrow_forward
- MARIE Code: Using the following MARIE Code attached, create a program that outputs the max and min of the array.arrow_forward8. using c++, Write a function method that determines the mean of all the values in an array of integers. Your mean function should call a separate function that you write that determines the sum. Don’t use built-in sum or mean gadgets, but roll your own.arrow_forward- in this exercise, please do not include and use string class. The function is using only array notation and manipulation.- string functions such as strlen is not allowed.- it should not have multiple return statements in the same function- there should be no global variable.- the function should not traverse the arrays more than once (e.g. looping through the array once only) write a c++ program named "isTheLastNumberTheMax" that accepts an array of integers and its size. It will return true if the last number in the array is the maximum number in that array and false otherwise. In addition, it also returns another boolean to indicate whether this list contains more than one maximum value.For example, if this is called with the array of {10, 20, 30, 40, 50}, it will return true and falseIf this is called with the array of {50, 10, 20, 30, 40, 50}, it will return true and true.arrow_forward
