The task involves writing a C++ program that determines the prime numbers between 1 and 100. The steps you should follow to identify the prime numbers are the following. 1. The number 1 is not a prime number, so it should be scratched. 2. Starting from the first prime number, which is 2, you scratch all the numbers that are the multiple of 2. You should not scratch out 2 itself. 3. The next number in the sequence after the...
