Write in C Language Description Please finish function merger. There are three parameter in function merger, a, b and c, all of them are pointer point to integer. Function merger will take five integer after pointer a and five integer after pointer b and puts them after pointer c byincreasingorder.   function int merger(int *a, int *b, int *c) { }

Call by value in programming means that a copy of variable value is pased from function calling part to function definition part. Call by reference means that an address of variables are passed from calling part to function definition.   arrow_forward Step 2 Call by reference is used to avoid extra memory usage because in call by reference same variables addresses are passed. Any changes made will reflect back. So it doesn't require extra variable to hold data. Call by value in programming is used where memory storage is not concern. Scenario in which actual value must not be disturbed then in these type of cases, call by value is used.  We can't use only one because user requirement changes. Sometimes user tella actual data should be preserved and he/she want any data processing, in such scenario programmers use call by value. Some users only want calculated result. In such cases, programmers use call by reference to preserve memory usage.  So it is totally dependent on user…

need help in C++ Problem: You are asked to create a program for storing the catalog of movies at a DVD store using functions, files, and user-defined structures. The program should let the user read the movie through the file, add, remove, and output movies to the file. For this assignment, you must store the information about the movies in the catalog using a single vector. The vector's data type is a user-defined structure that you must define on functions.h following these rules: Identifier for the user-define structure: movie. Member variables of the structure "movie": name (string), year (int), and genre (string). Note: you must use the identifiers presented before when defining the user-defined structure. Your solution will NOT pass the unit test cases if you do not follow the instructions presented above. The main function is provided (you need to modify the code of the main function to call the user-defined functions described below). The following user-defined functions are…

Given variables category, heat, and voltage, declare and assign the following pointers: • character pointer categoryPointer is assigned with the address of category. • integer pointer heatPointer is assigned with the address of heat. • double pointer voltagePointer is assigned with the address of voltage. Ex: If the input is V 150 5.5, then the output is: Product category: V Operational limit: 150 degrees at 5.5 volts. 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20} char category; int heat; double voltage; *Your code goes here */ cin>> category; cin >> heat; cin>> voltage; cout << "Product category: cout << "Operational limit: return 0; << *categoryPointer << endl; << *heatPointer << degrees at << fixed << setprecision (1) << *vol
