Write a C++ program that uses a 1D array to store 25 students' computer programming grades (total grade 100). The program should not accept incorrect or invalid grades, and the user should be able to enter marks one at a time. Once the user has completed the entry, the program should output the following. a) Maximum grade b) The average grade (sum of all grades/total number of students) c) Minimum grade Write the C++ code in the space provided (Full marks are awarded for a complete solution.)

Create Array of Random Dates In this task you are required to write a function that will generate a column array (a variable called dates) containing N random dates. N is an integer (whole number) entered by the user and will indicate to the function how many random dates the user requires. The dates array will be structured as follows: • The array shall have two columns; column 1 will contain numbers indicating the day of each month (1-31) and column 2 will contain numbers indicating the month (Jan 1, Feb=2, Mar = 3.... Dec = 12). . Each day must be randomly generated (using the randi() function) taking into account the maximum number of days in each month (i.e. Jan, Mar, May, Jul, Aug. Oct and Dec have 31 days, Apr. Jun, Sep and Nov have 30 days and Feb will have 28 days). You must use an if-elseif-else statement to decide this. • We are assuming no leap years (e. February can only have days between 1-28). For example, the output from calling the function: output = dategen (3) could…

Topic: Array covered in Chapter 7  Do not use any topic not covered in lecture.  Write a C++ program to store and process an integer array. The program creates an array (numbers) of integers that can store up to 10 numbers. The program then asks the user to enter up to a maximum of 10 numbers, or enter 999 if there are less than 10 numbers. The program should store the numbers in the array. Then the program goes through the array to display all even (divisible by 2) numbers in the array that are entered by the user. Then the program goes through the array to display all odd (not divisible by 2) numbers in the array that  are entered by the user. At the end, the program displays the total sum of all numbers that are entered by the user.
