int myArray[4][9]; How would you pointer arithmetic to calculate the position of the element myArray[3][2]? Note, this is independent of the size of the array elements because C will offset based on the size of the array element. For example myArray+4 would be the position of the 5th element in the array (i.e., element myArray[1][0])

- 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",…int arr[10]; Given the array declaration above, which of the following array operation are supported by the standard C library? i) arr.length() ii) arr[-1] iii) arr[3:4] iv) None of the above int arr[10][50]; The code above statically allocates a 2D array with 10 rows and 50 columns. If instead we were to allocate this 2D array dynamically, how many calls to malloc() would be needed such that we can still use the arr[i][j] access syntax? a) 10 b) 11 c) 50 d) 51 e) 1 char buf[50]; Given the character array declaration above, what would be the data types of the following? *buf buf1. Write a function named “getSumBeforeNegative” that takes in a pointer to the array of integers and its size. It will return the sum of all values before it sees a negative number. If there is no negative number in the list, it returns the sum of all numbers in the array.For example,int numList[] = {10,20,-1, 30);// will return 30int priceList[] = {10, 20, 30);// will return 60It must use pointers to integer instead of array index.Write a main program and show how this function is called and used.
- c++ make a simple prrogram that takes random 2d array entered by user and organizes it use pointers for example if the user enter ((8,4),(3,4),(7,2),(8,6),(3,1)) no limit to number of sets use pointers there should be a function called transformer that will transform them into the right order and a funtion called display that will display what was inputed then it would organize it into ((4,8),(3,4),(2,7),(6,8),(1,3)) IT should only modify it and not make a copy of it.2) Complete the below code by making the reuse of the existing functionality. Find the index of the equilibrium element in the given array. In an array equilibrium element is the one where the sum of all the elements to the left side is equal to the sum of all the elements on the right side. Return Value: 1) Return -1 if no equilibrium element is found 2) In case there is more than one equilibrium element, return the element with the least index value. You are supposed to complete the given code by reusing the existing function. You can click on Compile & run anytime to check the compilation/execution status of the program you can use printf to debug your code. The submitted code should be logically/syntactically correct and pass all the test cases. Code approach For the question: Correct the given implementation. Do not modify the approach. Test Case: a[] = {1,2,3,4,3,3}. 4 is the equilibrium element since its left side sum (1+2+3) is equal to its right side sum…Part 1 Write a function that takes an integer array and the size of the array The array is supposed to have 'N' integers in it, where N-1 integers are repeated even number of times and one integer is repeated odd number of times For example array = {1,5,5, 1,2,5,2,2,5}. 1 and 5 are repeated even number of times whereas 2 is odd number times. The function should find the element which is repeated odd number of times and return it. In the case of the example shown above, the function should return 2. int FindSingleElement(int arr[], int size) { } int main(int argc, char *argv[]) { return 0; } THIS IN C++.
- Java Program. Write a function that returns the index of the smallest element in an array of doubles. If there are more such elements than one, return the last index is fine. Using the following header: int IndexOfSmallestArray(double array[], int size) Finish the function implement only.please help solve this code using c++ arrays and pointers, and incorporate the following code: for (int i = 0 ; i < course ; i++) { // tell user which course is at cout << "Course "<< i+1 << endl ; // make pointer point to row arr[i] = new float [i+1] ; and then record assignment marks adding to the total for (int j = 0 ; j < entry ; j++) { // prompt for each course's entry cout << "Enter entry " <<j+1<< ": " ; cin >> score ; // store the score to each row arr[i][j] = score ; courseTol += score; }Write the code that dynamically allocates memory for an array of 10 integers and assigns its address to the pointer ptr. After that use that pointer to access the array and store on it the powers of two then display the content of the array on the screen. The output should be: 2 4 6 8 16 32 128 256 512 1024. Note: You can use the pow() function. This function takes two arguements and returns the result of the first argument raised to the power of the second arguement.
- 1. Write a function named "isBoundedArray" that accepts an array of integersand its size. The function will check the array to see whether the first and the last elementsin the given array are the smallest and largest in the list,or the largest and smallest in the list.If they are, it will return true. Otherwise, it will return false. Requirement: please use only pointer notation in the function. No array notation. For example, the following arrays will return true int numList0[] = {10} ; int numList1[] = {10, 20, 30, 40} ; int numList2[] = {40, 30, 20, 10} ; int numList3[] = {10, 30, 20, 40} ; int numList4[] = {40, 20, 30, 10} ;And these arrays will return false int numList5[] = {10, 40, 20, 30} ; int numList6[] = {40, 20, 30, 50} ; 2. Write a function named “isBinaryString” that accepts a C-string (an array of characterswith a NULL terminating character)and returns trueif that C-string contains a valid binary number and false otherwise. A valid binary string is defined…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.Write a program called "pointerArray.cpp" using knowledge of pointer. The program must illustrate the use of a pointer that point to the content of an array and to display the contents of an integer array {5, 10, 15, 20, 25, 30, 35, 40} in order and reverse order. For example the output should be as follows: The numbers in the array are: 5 10 15 20 25 30 35 40 The numbers in reverse order are: 40 35 30 25 20 15 10 5
