This is a c++ question task do it carefully and do that in simple words and don't copy from the internet or do any plagarism.

There are actually 4 simple mathematical problems. solve all these problems.

Write the CPP code here in text and do these 4 tasks (don't do it together)

For ex - p1.cpp , p2.cpp , p3.cpp , p4.cpp by this .

Paste the code here ( Don't plagiarise)

Extracted text: C++ Basics: The lab instructor will familiarize the students about the C++ environment and coding style. The instructor should demonstrate cout, cin and other basic commands to students. Tasks: 1. Take 2 integer inputs from keyboard and print their sum. 2. Take an integer from keyboard and find its factorial. 3. Take 2 integer inputs from keyboard and also ask the user for which operation to perform: +' or *-'or *. Perform the appropriate operation and show the result. (Hint: you can use switch/case) 4. Write a function isPrime(int n) which checks if 'n' is prime or not. Use this function to print all the prime numbers between 300 to 500.
