struct studentType { char name[26]; float avg; int sID; char grade; }; ---USING POINTERS--- Write a program that will dynamically allocate an array of studentType.

C++ Create a program that reads a simple arithmetic expression and evaluates it. More precisely, the program reads from the user a line of text that’s supposed to contain two numbers separated by an arithmeticoperator, as in: 35.6 + 12 The program then prints back the expression and its value, as in: 35.6 + 12 = 47.6 The program should verify that the input line contains two numbers, one operator and nothing else. There can be whitespace before the first number, after the second number and between each number and the operator.The operator can be either +, −, *, or /. In case of an error, the program should print: "Invalid expression" and quit.When the program prints the expression, there should be no whitespacebefore the first number and there should be exactly one blank space beforeand after the operator and the equal sign.Use string streams.

THIS IS FOR C++ ONLY Part 2b: Password Verification A secure password is critically important in today's world. Organizations typically have stringent requirements to ensure a password is complex enough so as not to be easily hacked. Write a program that will accept as input a potential password and determine whether or not it is valid in meeting the following criteria: at least eight characters long at least one uppercase letter at least one lowercase letter at least one digit at least one special character (you can determine what is acceptable) If the password is valid, ask the user to enter it again. If it matches, indicate the password has been accepted. If the password does not meet any of the above criteria, indicate which it does not meet.
