The program separates the user interface (command-line) and the internal processing subsystem. The internal processing system consists of the following classes: • • Contact Manager (responsible for add and delete operations) Contact Finder (responsible for the search operation) pataManager (responsible for save and load operations) a. What design pattern can be used to implement the user interface? Explain your answer using a class diagram for the entire system. b.

- Implement a C program to find the largest element in a given array. You must have a main function and a max function. The function int main() will declare an array with the values {12, 100, 10, 1000, 20, 5}. This array will be passed to the max function. The function int max() will perform the necessary operations to find the largest element of the array. After max () is finished, have main () print the largest value and its index in the array. Do not hard code your solution! If we test your code with different array values, we should still get the correct output. The following link may help you get started: https://www.tutorialspoint.com/cprogramming/c_function_call_by_reference.htmarrow_forwardPlease run the following program and answer the questions. #include int main(void) { int arr[6] = int *pointer pointer *pointer = {10, 20, 30, 40, 50, 60}; = &arr[0]; pointer + 2; = 5 ; pointer++; *pointer - (*pointer) 5 ; pointer++; *pointer * (pointer+1) - 5%; return 0; 1.
