- Using C++ Language In this program, you will write a program that uses a function to compute the maximum value in a randomly generated array of integers. Inside your main function, declare an array of size 10. Using a suitable loop, generate seeded randomly generated numbers between 50 and 100 inclusive. Display the randomly generated numbers using a suitable message. Call a function that returns the maximum value of the array. You will need to pass this array to a function. The function does not need to modify the array, hence pass it as a constant array. Use a global constant for the size of the array. You must display the maximum value of the array in the main function.arrow_forwardRecall the following segment of Java code for computing the set-difference of two given arrays (note that the lines have been numbered for the sake of reference): (1) int[] a, b; (2) (3) (4) (5) (6) (7) (8) (9) (10) count=0; (11) for (int i=0; i<=a.length-1; i++) { (12) (13) (14) (15) (16) (17) (18) (19) (20) (21) (22) (23) } (24) (25) int[] ans = new int[count]; (26) for (int i=0; i<-count-1; count++) (27) // Input the arrays a and b here int[] tempAns; int count,j; boolean found; tempAns = new int[a.length]; found = false; j-e; while (j<-b.length-1 && !found) { if (a[i]==b[j]) found = true; j+; } if (!found) { tempAns[count]=a[i]; count++; } ans[i] = tempAns[i]; Suppose we want to modify the above code to compute the set union of the arrays a and b, i.e., the set of all elements that are in either a or b.

- Language is C++ Lab10B: Binary Bubbles. Binary search is a very fast searching algorithm, however it requires a set of numbers to be sorted first. For this lab, create an array full of 11 integers which the user will generate. Like in the previous lab, assume that the values will be between -100 and +100. Then, using the sorting algorithm called BubbleSort, put the array in the correct order (from lowest to highest number). After this, please printthe array to the screen. Finally, search the array for the target value using Binary Search.The BinarySearch code will implement the algorithm described in the lecture slides. During this, you should print out a few key values which help Binary Search function. For example, this algorithm focuses on a low, mid, and high which correspond to the indices in the array the algorithm is currently considering and searching. Printing these values during the search process will help with debugging and fixing any issues. • BubbleSort sorts the array…arrow_forwardPlease help guide me in the direction what I am doing wrong.

Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results.
