## sum of the first n positive integers

Write a program that computes the sum of the first $$n$$ positive integers, where $$n$$ is specified by the user. Let's assume for now that $$n>0$$ and $$n<500$$. Test it on $$n=5$$, $$n=50$$ and $$n=500$$, the output should be:

the sum of the first 5 positive integers is: 15
the sum of the first 50 positive integers is: 1275
the sum of the first 500 positive integers is: 125250
