Question
C program
Create random array with user-defined size
Write the CreateNewArray() function, which creates an array of any size and randomly fills it with integers in the interval [min, max).
Function inputs: the size of the array (int), a seed value for the random number generator (int), and the values min and max defining the interval [min, max) (both ints).
Function outputs: a pointer to the newly created array of integers.
main() is mostly written for you. It reads in all inputs from the user, calls CreateNewArray(), and prints the array's entries. However, you will need to add a statement at the end of main() to free the memory that you allocated in CreateNewArray().
Reminder: If you dynamically allocate any memory, you MUST free that memory before the end of your program.
Note: Inside CreateNewArray(), use srand() to seed the random number generator and rand() to generate random integers in the interval [0, RAND_MAX]. Both functions are accessible in stdlib.h.

- C++arrow_forwardHelp now please Pythonarrow_forwardWrite the main program to create an array of size 10. Create two integer variables called max and min. Write a function to accept this array and its size. This function must populate the array with random numbers in the range -400 to 300. Write a different function to accept this array, its size and the address of the two variables max and min. The function must find the max and min of this array and write it to the min and max using pointer notation. Print the array and the values of max and min in the main program. in C++ visual studioarrow_forward

- Assume that the integer array myScores has been declared and assigned values. Assume that the integer variable size has been declared and initialized using the number of elements in the array myScores. Write a code block that declares a pointer to an integer and initializes it using the address of the array. Use that pointer to access the array elements, compute their average (as double), and display it on the screen.arrow_forwardOne dimension array in C:Create an array of 100 integer elements and initialize the array elements to zero.Populate the array (using a for loop) with the values 10,20,30,..., 990,1000.Write code (using for loops) to sum all the elements and output the sum to the screen. without using #definearrow_forward
