(Program) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters, such as zerocount, onecount, twocount, and so forth, to 0. Then generate a large number of pseudorandom integers between 0 and 9. Each time 0 occurs, increment zerocount; when 1 occurs, increment onecount; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of time they occurred.
Write a program to input a list of numbers in an array and then rearrange this array in such a waythat all the odd numbers appear in the beginning of the array and all the even numbers appear in theend of the array. E.g., if the input list is 1,4,2,7,6,5,9, then after rearrangement the list should be:1,7,5,9,4,2,6. program should be in c language.
write a C++ program define two lists of numbers (arrays) and ask the user to give the size of each, and then ask the user to fill the list(according to a size that he gave), then compare two arrays and determine whether they are equal? (Note: two arrays are equal if all elements are equal.)
Write a c++ program to declare an array of odd number of elements. Split it into the middle and store the elements in two different arrays. e.g. Initial array: 22 58 19 87 15 72 9 1 37 After splitting: 22 58 19 87 15 72 9 1 37 As output, your code should print the original and the two split arrays, each element separated by the comma sign. Your code should be generic enough to also work for arrays with an even number of elements.
Write a c++ program to ask the user for the number of arrays he wants to maintain and then populate each array by taking elements from the user. Merge all these arrays in another array and finally remove duplicateelements from the merged array.
Write a C++ program that can shift the elements of an array to the left based on a value that received from the user indicating the number of shifts (n). Any elements that falls off at the beginning of the array must be added to the rear of the array so that the number of elements in the array remains unchanged. For example: before shift: int array = {1,2,3,4,5,6,7,8,9,10} after shift: array = {6,7,8,9,10,1,2,3,4,5}, where n=5. The array with the new order of values must be displayed to the user again. Tip: Use a temporary array to save the new order of digits before the original array is overwritten, one element at a time.
Write a C/C++ program that takes an input (array) from 1 to n (say n = 50) and displays the string representations of those numbers with following conditions If the current number is divisible by 2, then print CSU If the current number is divisible by 5, then print LB If the current number is divisible by both 2 and 5, then print CSULB If the number is neither divisible by 2 nor 5, then print the number Example: 1 CSU 3 CSU LB CSU 7 CSU 9 CSULB 11 CSU 13 CSU LB CSU 17 CSU 19 CSULB … Tasks to do: (4%) Implement the solution using a single thread (i.e., without using threads and only a main function with any other possible helper function for ease) with all the above conditions implemented in the correct order so that the results are correct. Reason about what can cause the algorithm to print unwanted results (think about the order in which you will write the above…

(a) Write a program to input a list of numbers in an array and then rearrange this array in such a waythat all the odd numbers appear in the beginning of the array and all the even numbers appear in theend of the array. E.g., if the input list is 1,4,2,7,6,5,9, then after rearrangement the list should be:1,7,5,9,4,2,6. (b) What does the term cast refer to? Why is it used? Justify your answer by considering a suitableexample.

write a c++ program. where you have to work with a 2-d array such that each row can have different number of cols. e.g. row 0 has 2 cols, row 1 has 3 cols. Use dynamically allocated arrays. Input the number of rows from the user. then ask the user to input the number of cols of each row. Then ask the user to input the elements of each row. Finally display the sum of elements of each row.
Write a C++ program that creates a 2D integer array of user-defined row size only. Initially, it has only 1 column, but it asks that does the user want to add a column to the array and then takes integer values to fill up the newly created column. It continues to do so until the user enters N/n to exit the program. For Example: Matrix: 1 2 4 8 Do you want to Add a column: y Enter the values in columns: 7 9 So updated Matrix is: Matrix: 1 2 7 4 8 9
