Write a C++ program that reads an integer maxAllowed and in output prints all elements less than the value maxAllowed from the array given below. Print -1 if all elements are greater than maxAllowed variable. int Array[10] = {67, 49, 11, 90, 123, 98, 8, 176, 34, 102};

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.)

d) Write a C++ program to find the missing number in an array containing numbers from 1 to 20. int arr[19] = {12, 13, 17, 1, 4, 9, 2, 20, 8, 3, 7, 10, 14, 15, 18, 6, 11, 16, 19};
