Forget about prime numbers. Write a function that returns the maximum product of any two members of your array.

Then modify the function so that only members with prime numbers are multiplied.

And you are done.

Hi, I'm having problems with this C program. Whenever I run it, it doesn't print anything. The program is supposed to compute and display all the prime numbers from 1 - 300 using the sieve of eratosthenes and using arrays (passing arrays to functions). Whenever i run it the compiler compiles it, shows a window for half a second, and closes again. Here is what I've done so far: /* This program uses the Sieve of Eratosthenes to * find all the...

However my attempts to use this in Python keep returning none (obviously no match), however I don't see why, I was under the impression Python used the same RE system as Perl/Ruby and I know the convert is producing the correct display of...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
