You will allocate and free memory in a simple program where you can add or drop students from a class. We supply code for a simple student class with data members name and GPA. In main we declare a vector of pointers to the student class. You will fill in two sections of code.1) You will define a student member function called ToString which returns a string containing basic student information. For a student named Jane with a GPA of 3.76 the string returned would be:You will create the string using an ostringstream from sstream. Note that you need to setprecision to 1 for that stream.2) You will write the main function as specified below.

The value of sin(x) (in radians) can be approximated by the alternating infinite series create a function (prob3_2) that takes inputs of a scalar angle measure (in radians) and the number of approximation terms, n, and estimates sin(x). do not use the sin function in your solution. you may use the factorial function. though this can be done without a loop (more efficiently), your program must use (at least) one. you may find the mod() function useful in solving the problem.
