- Write a single line of code that will accomplish the following: declare arr to be of type "pointer to a char" allocate a dynamic array of type char with capacity 4 assign the starting address of the array to arr HINT: Use conventional spacing (one space each side of the = operator) and don't forget your semicolon.Below you will find code blocks necessary to insert a value into an ordered array given a position (index) to insert. Be careful! Some lines are not needed. first line COMPLETED: bool insertElement(char array[ ], int& numElems, int &capacity, in position, char value) { last line COMPLETE: bool insertElement(char array[ ], int numElems, int capacity, in position, char value) {Create two dynamic arrays A and B with random numbers.a) Merge B in array A calling a function by reference.b) Delete the Prime numbers from the merged array A calling a function by pointer.c) Print the Array A in ascending order.You have to use only two Arrays A and B throughout the code. Be carefulabout memory leakage.Example:A= [20, 30, 5, 7, 19]B= [19, 10, 15, 11, 17, 25] a) After merging B in A, the merged Array A will look like-A= [20, 30, 5, 7, 19, 19, 10, 15, 11, 17, 25] b) After deleting prime numbers the merged Array would look like-A= [20, 30, 10, 15, 25] c) Finally print the merged array in ascending orderA= [10, 15, 20, 30, 25] In C++ Please

- Objective: To write a program to remove duplicates from an array entered via the command line. Please write a program to remove duplicates from the series of numbers specified on the command line. So your program should output just the distinct numbers that were on the command line. Sample output is below: MUST BE ABLE TO INPUT NUMBERS VIA COMMAND LINE > java -classpath .:/run_dir/junit-4.12.jar:target/dependency/* Main usage: java Main 5 4 2 4 8 To remove duplicates from the numbers 5, 4, 2, 4 and 8 > java Main 5 4 2 4 8 Here are the distinct numbers: 5, 4, 2, 8 > java Main 1 3 5 2 3 5 3 3 5 7 9 3 Here are the distinct numbers: 1, 3, 5, 2, 7, 9Which one of the following function prototype can possible do the following? A function with one reference parameter is a pointer to an integer. The function allocates a dynamic array of n integers, making the pointer point to this new array. It then fills the array with 0 through n - 1. Group of answer choices void exercise(int*& p, size_t n); void exercise(const int*& p, size_t n); void exercise(const int p, size_t n); void exercise(int& p, size_t n); void exercise( int p, size_t n);Write a public VB.Net subroutine that does the following: • Declare an array of integers of size larger than 5, you can determine the size. Read values from the keyboard to fill the array. Use inputbox to do this. Find the maximum value and subtract it from all elements in the array. Return the maximum value using a reference parameter. Note that this a subroutine not a function
- Write a program that accepts two integer values, called "arraySize" and "multiplier", as user input. Create an array of integers with arraySize elements. Set each array element to the value i*multiplier, where i is the element's index. Next create two functions, called PrintForward() and PrintBackward(), that each accept two parameters: (a) the array to print, (b) the size of the array. The PrintForward() function should print each integer in the array, beginning with index 0. The PrintBackward() function should print the array in reverse order, beginning with the last element in the array and concluding with the element at index 0. As output, print the array once forward and once backward.Create a file called unsorted.dat and copy (or type) the following floating point numbers into that file. 12.75 9.39 -15.25 18.34 12.65 -23.78 15.25 10.42 7.39 Now, create a program file called Time3.cpp with the following requirements. • In your main function, read the unsorted.dat file in an array. You do not know exactly how many numbers there are in the file (your program should be generic), so declare an array of sufficiently large size and use the while loop to read the numbers into the array. • Then, use a programmer-defined function to sort this array in ascending order. You cannot create a separate array for this purpose. You need to call this function and pass the array to this function from the main function. • In your main function, write the sorted array to an output file named sorted.dat.Write a block of code that uses a dynamic allocated array named Array to (1) Load ten integers from the user into the memory, (2) Find the number of negative integers in the array, and (3) Print a message with the number of negatives. Whenever no numbers are negative print an additional message "No negatives!" (Assume all libraries are included)
