Fill the validateForm function to check that the phone number contains a number (use the isNaN function) and that the user name is less than 11 characters long. Display "Phone number is invalid" and/or "User name is invalid" in the console log if the check does not pass. Use the preventDefault function to avoid submitting the form when the inputs are invalid. let form = document. getElementById("userForm");

function validateForm(event) {
let phoneNumber = form. phoneNumber. value;
let userName = form. userName. value;

/* Your solution goes here */

}

form. addEventListener("submit", validateForm);

Consider the following statements: struct nametype{string first; string last; }; struct coursetype{string name; int callnum; int credits; char grade; }; struct studenttype{nametype name; double gpa; coursetype course; }; studenttype student; studenttype classlist[100]; coursetype course; nametype name; mark the following statements as valid or invalid. if a statement is invalid, explain why. a.) student. course. callnum = "csc230"; b.) cin > > student. name; c.) classlist[0] = name; d.) classlist[1].gpa = 3.45; e.) name = classlist[15].name; f.) student. name = name; g.) cout < < classlist[10] < < endl; h.) for (int j = 0; j < 100; j++)classlist[j].name = name; i.) classlist. course. credits = 3; j.) course = studenttype. course;
