Write a program to test for primality of any number n (that is, to test if n is a prime number). start by writing an algorithm (a set of precise mathematical steps that can be written into a program) to test for primality. for full credit, run the program and use it to test for primality on several numbers. see what the largest number your program can handle is before you find it too slow to yield a result in a reasonable time (if it takes longer than 10 minutes to execute, you are done). use your own imagination. remember that if the number n is even, it cannot be a prime number. you can write your program to simply try if it is a multiple of any numbers smaller than n. also you can design your program to store all prime numbers less than n that your program has found, then take advantage of the fact that a number only needs to be tested to see if it is a multiple of those prime numbers smaller than n/2. if it is not, then it must be a prime number itself.

Write a program that inserts the digits of an integer into an array in originalorderfollowed by reverse order. first, promptthe user to enter a positive integer(> 0). determine the number of digits of the integer. create a dynamically allocated integer arrayof a size twice the number of digits. now insert the digits in original order which will occupy half of the array. then, insert the digits in reverse order. finally, output thedigits in thearray. use at least two functions to organize your program.

Scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below. what experimental evidence led to the development of this atomic model from the one before it? a few of the positive particles aimed at a gold foil seemed to bounce back. the colors of light emitted from heated atoms had very specific energies. experiments with water vapor showed that elements combine in specific proportions. cathode rays were bent in the same way whenever a magnet was brought near them.
