(Statistics) a. Write a C++ program that reads a list of double-precision grades from the keyboard into an array named grade. The grades are to be counted as they’re read, and entry is to be terminated when a negative value has been entered. After all grades have been input, your program should find and display the sum and average of the grades. The grades should then be listed with an asterisk (*) placed in front of each grade that’s below the average. b. Extend the program written for Exercise 1a to display each grade and its letter equivalent, using the following scale: Between90and100=AGreaterthanorequalto80andlessthan90=BGreaterthanorequalto70andlessthan80=CGreaterthanorequalto60andlessthan70=DLessthan60=F
Write a program that uses random number generation to create sentences.The program should use four arrays of pointers to char called article, noun, verband preposition. The program should create a sentence by selecting a word atrandom from each array in the following order: article, noun, verb, preposition,article and noun. As each word is picked, it should be concatenated to the previouswords in an array large enough to hold the entire sentence.The words should be separated by spaces. When the final sentence is output, itshould start with a capital letter and end with a period. The program shouldgenerate 20 such sentences. The arrays should be filled as follows: The article arrayshould contain the articles "the", "a", "one", "some “and "any"; the noun arrayshould contain the nouns "boy", "girl", "dog", "town" and "car"; the verb arrayshould contain the verbs "drove", "jumped", "ran", "walked" and "skipped"; thepreposition array should contain the prepositions "to", "from", "over",…
İN C PROGRAMMİNG Write a program that fills an integer array of size 1000 with random positive integers between 1 and 10. Assume that each element represents a different city and the integers stored in the array represent the number of golds in those cities. The program traverses over the array and collects the golds at each city, starting from a random position. When the program visits a certain city, all of the golds are collected, and the visited element of the array becomes 0 (no gold is left at that city.) The journey continues with the rule given below. If the position at the nth step is denoted by pn, and the number of golds at the city pn is denoted by gn, ??+1 ={|(?? +??) ???1000|, ?????2=0. |(?? − ??) ??? 1000|, ????? 2 = 1 The program continues visiting cities until the last three visited city has no gold. The program, at each visit, should print out the following information: • The current city index (pn). • The previous city index (pn-1). • The number of golds at the…
3. Pointers – Arrays: initializing content • Using the pointer ptrArray, you now want to write values in those integers. Use a loop to go through each element in that array, and initialize them all to 42. This is done in the main. 4. Pointers – Arrays: printing • Write a function that will print the elements in the array-pointer. The function should accept a pointer to an integer, and the size of this array. The function should not return anything. Here is your function prototype: void printArray(int* ptr, int nb); • Your function needs to use a loop to go through all the elements in the array, and simply prints them on a new line. • In the main function, call this function with your pointer ptrArray and the size given by the user.

C Programming Write a function that takes a double array arr, its size n, a value v and an int array indices asparameters. The function places the indices of the elements in arr with the value v into indices and returns thenumber of elements placed into indices. (You can assume that the indices array is sufficiently big)

3. Selection Sort• The idea in a selection sort is that you locate the largest item out of a set ofunsorted items, and move it into position at the end of the unsorted items. Asorted region grows one item at a time, while an unsorted region shrinks.• As done in Part 1, fill an array with random numbers.• Write a function that locates the largest element in the portion of the arraybeginning at the start of the array, up to a given index, and swaps the largestitem with the item at the given index.• E.g. If searching a[0] to a[7] locates the largest item at a[4], a[4] and a[7] would beswapped.• Write a second function that calls the first function repeatedly, until the entirearray is sorted. (Each time the first function is called, it will search one fewerelement)

Randomly generate a partially filled array of unique values.a) Create a blank partially filled integer array of capacity 10.b) Implement an array print function.c) Implement a hasValue function which accepts the array and an integervalue as input. It checks the array for the value and returns trueif the value exists, false if it does not.d) Implement a randArray function which initializes the array with randomintegers between 0 and 9 inclusive. This function should use thehasValue function to ensure all values are unique (no duplicates).e) Print the array. Confirm that all values (0-9) are included. Example 1 Output (input in bold italics) 2 5 8 9 3 4 0 1 7 6Example 2 Output (input in bold italics)5 9 3 4 7 0 1 6 2 8
