Arrays write a C++ program that will declare two static arrays where each will hold the contents of a file (random.txt) of 200 integer values. Sorting Using the two arrays, call a private member function that uses the bubble sort algorithm to sort one of the arrays in ascending order. The function should count the number of exchanges it makes. Display this value. The program should then call a private member function that uses the selection sort algorithm to sort the other array. It should also count the number of exchanges it makes. Display this value. Searching Next, call a private member function that uses the linear search program to locate the value 869. The function should keep a count of the number of comparisons it makes until it finds the value. Display this value The program then should call a private member function that uses the binary search algorithm to locate the same value. It should also keep count of the numbers of comparisons it makes. Display this…
