Part 1
Write a program called "numbers" that accepts two positive integer arguments from the user and prints:
1. The average of the two numbers, printed as a floating-point number.
2. A value indicating whether each number was prime or not.
3. A value indicating whether the two numbers were relatively prime or not (use whatever algorithm that you can find online).
You can assume that the user will input only positive integers, i.e. you don't have to validate their input.
Here is an example run of the program:
shell $ ./cmake-build-debug/numbers 1 2 You typed in 1 and 2. The average is 1.500000. The first number, 1, is prime. The second number, 2, is prime. 1 and 2 are relatively prime. Directory Layout
Several files have been included; you just need to complete the functions that are marked as "not yet implemented":
average.h and average.c contain the avg function gcd.h and gcd.c contain the gcd function prime.h and prime.c contain the is_prime function numbers.c contains the main function which will call these other functions.
Build and Test
To build the assignment, simply run the ./build.sh script. To run the tests, run the ./run-tests.sh script. To run the program, first run the build script, then run ./cmake-build-debug/numbers.
Hints!
You can use ```c int x, y; x = 42; y = 143; printf("You typed in %d and %d ", x, y); ```
...to print integers, and ```c float f; f = 143.42; printf("The average is: %f ", f); ```
...to print a floating point number.
Part 2
Write a program called "convert" which reads a signed integer from standard input, saves that input to a variable of type int, and then interprets that variable's bytes in four different ways:
1. As a signed decimal
2. As an unsigned decimal
3. Encoded as a hexadecimal (base-16) string
4. Encoded as a binary (base-2) string
Some example runs of the program:
shell $ printf '%s' '1' | ./cmake-build-debug/convert signed dec: 1 unsigned dec: 1 hex: 1 binary: 0000 0000
0000 0000 0000 0000 0000 0001
shell $ printf '%s' '-1' | ./cmake-build-debug/convert signed dec: -1 unsigned dec: 4294967295 hex: ffffffff binary: 1111 1111 1111 1111 1111 1111 1111 1111 Hints!
The scanf function can be useful for reading characters from stdin and interpreting those characters as a number:
```c float f; scanf("%f", &f); // blocks until user enters a number and hits enter printf("%f ", f); // prints the user input
int x; scanf("%d", &x); // %d is different than %f (run man 3 scanf in terminal) printf("%d ", x); ```
