The Problem: Lots of functions return a pointer when returning a good
value and NULL on error. We a quick way of testing for NULL.
Step by step
Solved in 2 steps
- In C++, define a “Conflict” function that accepts an array of Course object pointers. It will return two numbers:- the count of courses with conflicting days. If there is more than one course scheduled in the same day, it is considered a conflict. It will return if there is no conflict.- which day of the week has the most conflict. It will return 0 if there is none. Show how this function is being called and returning proper values. you may want to define a local integer array containing the count for each day of the week with the initial value of 0.Whenever you have a Course object with a specific day, you can increment that count for that corresponding index in the schedule array.‘Write a function has_unique_values() that takes a dict as a parameter and returns True if the keys have unique values (that is not two keys have the samevalues) Write several assertion to test this function.C Program Functions using Pointers Create a function modify that accepts an integer and divides the integer by 2 if it is even. If the integer is odd, add one and divide it by 2. The function does not return anything. In the main function, write a program that asks for an integer input and call the modify function by passing in the reference of that variable as a parameter. An initial code is provided for you. Just fill in the blanks. Input 1. One line containing an integer input Output Enter a number: 5 Before: 5 After: 3
- Write a C user defined function array and a value which you want to find in the array. (function may be needs more parameter to perform it) The function should check values of the array and if it find the same value in the array, it should return the position in the array (just first one). If there is no match, it should return "-1" Example: if array is {1,2,5, 3, 10, 5) and if the search term is "10" function must return 4, If the search term is "5" function must return 2, If the search term is "9" function must return -1,Please enumerate all of the situations when invoking inline functions will not get the expected results.Enumerate all the situations where inline functions does not work .
- Complete the following function using pass-by-reference: void findMax(int &max, int a) which assigns value ‘a’ to ‘max’ if a > max. Write a pseudo-code then implement a program in C language to find the maximum in a sequence of numbers using this function.In C++ use the following STL algorithms: reverse, rotate, and shuffle. Write versions of these functions using the same parameters as the original functions but using your own definition of the function body. Use each function at least three different times in a test program to make sure the function operates properly. The data sets you use for testing should contain at least twenty elements.Computer Science In C++ use the following STL algorithms: reverse, rotate, and shuffle.

Use each function at least three different times in a test program to make sure the function operates properly. The data sets you use for testing should contain at least twenty elements
- Write the definition of a void function that takes as input two integer values, say n and m. The function returns the sum and average of all the numbers between n and m (inclusive) .8. using c++, Write a function method that determines the mean of all the values in an array of integers. Your mean function should call a separate function that you write that determines the sum. Don’t use built-in sum or mean gadgets, but roll your own.Using C++ Write the section of code which takes an array of characters and copies it to another array of characters. At this point two arrays of characters should hold the same name. You will need to use one of the loop instructions to do this. You can't use any built in functions. Write a second section of code which concatenates two arrays of characters into a third array of characters. The first array (which holds the first name) will be copied into the third array and the second array (which holds the last name) will be concatenated onto the third array. Once you are done filling in the arrays you should output the two sentences below. You are given the example input and output below.Example Input: Input first name -> FredInput last name -> SmithExample output: Your first name is Fred and the copy of your first name is Fred. Your first name is Fred and your last name is Smith and the concatenation is FredSmith.
