This repository contains templates for performing automated grading of
Python, C and C++ code. The required source code and the associated autotests
are in the c, cpp and py directories. The definitions for github actions
to run the tests and perform automated grading reside in .github.
The task is to write a program
that implements the function sum_to(num) which adds up all integers
between 0 and a user-defined upper limit num,
i.e. 1 + 2 + 3 + ... + num. The upper limit has to be integral and must
be included in the sum.
For the task at hand, one could use 25 as a common case for the
upper limit. A good addition would be 26 to have at least one common
case of an even number for the upper limit. The edge cases for the problem at
hand usually include 0 (the smallest unsigned integer) and
4294967295 (the largest 32 bit unsigned integer).
Expected results for these are 325, 351, 0 and
9223372034707292160.
In addition it would be good to also add, for example, 500000000 as
input (expected result 125000000250000000) as 4294967295 does
not terminate at all when students fall for a common programming mistake.
