Assignment

Required reading: Sections 1 (The idea of a loop) and 2 (While loop examples) from the Unit 3 notes.
Write a program called gauss.c that reads an integer $n$ from the user, and then uses a while loop to add up the numbers from 1 to $n$ and print out the sum.
For example, if $n=5$, then the result would be $1+2+3+4+5$, which comes out to 15.

Example of running your program:
```
roche@ubuntu$ ./gauss
Enter n: 5
The sum of numbers from 1 up to 5 is 15
roche@ubuntu$ ./gauss
Enter n: 100
The sum of numbers from 1 up to 100 is 5050
```
