How to tune Vim, use the C compiler and more about the shell

Quiz 02

Once everything is setup do the following on our server theon:

Create a file quiz02_hello1.c with the following content:
session02/tmp/quiz02_hello1.c
1 2 3 4 5
int main() { puts("hello, world!"); }

Compile this source file and run the generated executable hello1 as follows (it is intended that you see some warnings here)

theon$ gcc -o hello1 quiz02_hello1.c
quiz02_hello1.c: In function 'main':
quiz02_hello1.c:4:5: warning: implicit declaration of function 'puts' [-Wimplicit-function-declaration]
    4 |     puts("hello, world!");
      |     ^~~~
quiz02_hello1.c:1:1: note: include '<stdio.h>' or provide a declaration of 'puts'
  +++ |+#include <stdio.h>
    1 | int
theon$ hello1
hello, world!
theon$

Note that gcc produces a warning but not an error! So despite its concerns gcc actually created a executable (and correct) program.

Copy the output produced by gcc (i.e. the warning in the box above) in a file quiz02_hello1.txt.

Create a file quiz02_hello2.c with the following content:

session02/tmp/quiz02_hello2.c

int puts(const char*);

int
main()
{
    puts("hello, world!");
}

Compile this source file and run the generated executable hello2 as follows
```
theon$ gcc -o hello2 quiz02_hello2.c
theon$ hello2
hello, world!
theon$ 
```
Copy the output produced by hello2 in a file quiz02_hello2.txt.
Submit the created files using the submit command as follows:
```
theon$ submit hpc quiz02 quiz02_hello1.c quiz02_hello1.txt quiz02_hello2.c quiz02_hello2.txt
theon$ 
```
Not that quiz02 you only get some feedback from submit if there was a problem. So “no news” means “good news”. That's because in this submission we have no automatic tests for your submission, i.e. we accept anything.
