add_prime_sum

Your mission

Write a program called add_prime_sum that computes and prints the sum of all prime numbers up to and including the integer passed as its only argument.

See it in action

./add_prime_sum 10

Expected result

Your checklist

For your own tracking. Tests grade your code.

The program takes exactly one argument (argc must be 2): a strictly positive decimal integer N.
If no argument is provided, or more than one argument is provided, print 0 followed by a newline and exit.
A prime number is a whole number greater than 1 that has no divisors other than 1 and itself.
Iterate from 2 up to N (inclusive), accumulate every prime found, then print the total followed by a newline.
You may only use write and exit.
