Define an user defined C++ function to find out the average of four integer numbers. The function should take the values those are passed as parameters and returns the average to the main function. Sample input: Enter four integers: 10 20 30 42 Average: 25.50

In c programming Your faculty was born in the year 1997 and he loves the digits of this number. So he is asking you to write a code where you will be given a string of digits as input and you need to find whether all the digits 1,9, and 7 is present in that string or not. Use function to solve this problem. [Hint: Write a function that will find a particular character in a string and call that function thrice to find each of 1,9, and 7 in the given string.]   Sample Input 1: 36892502945417835   Sample Output 1: Yes   Explanation 1: All 1, 9, and 7 are present in the number   Sample Input: 3689250294547835   Sample Output: No   Explanation: The digit 1 is missing from the input string

Write a function with one integer parameter that will return the sum of the divisors of its argument c++

Write a complete C++ program that helps the teacher to calculate the result of students in the test of Programming Technique. The program should perform the following tasks: Task 1: Write a function named getInput. a) This is a non-returning function. b) It takes the score of question 1, score of question 2, and score of question 3 as input parameters. c) The function should ask the user to enter the score (per 100) for each question. It sends all the values entered by the user in (c) back to the calling module through the use of reference parameters. d)
