findPrimes

This is a program designed to find all the prime numbers between 2 and a given number.

Usage:

findprimes [threads] [method] [n] [outputFile]

You can tell the program to use multiple threads by providing a number for threads. If the number of threads is invalid, the program will exit with an error.

You can tell the program to use a specific method by providing a character for method. For methods you can choose between '0' '1' '2' '3' '4'.

0 stand for Trial Division.

1 stand for Sieve of Eratosthenes.

2 stand for Sieve of Euler.

3 stand for Sieve of Sundaram.

4 stand for Incremental Sieve.

n stand for the upper limit of the primes you want to find.

outputFile is the file that you want the primes to be output.
