For 50 points, write a program called Primel which reads an endless sequence of integers from stdin and tests whether each number is prime or not and prints a meaningful message to stdout if it is. Example program output is shown below Place all your code in "Prime1 cpp" including function "isprime int)" which is a boolean function that does all the checking. As usual, the endless input ends when CTRL-D is encountered. checking. As usual, the enmel cpp" including is, Example For 50 points, write a modified version of Primel called Prime2. Move the "isprime(int)" code into a class called "isprime" that overloads its function operator to act as a function object. Instantiate an "isprime" object in the main program and use it to test the input data. The program output is as shown below
