Output:
Cannot open afile1
Second try, afile1 was opened
afile1 was closed
afile2 was opened
afile2 was closed
Explanation:
afile1 must exist before it can be opened for reading (r) or the
fopen function will fail. If the fopen function opens a file for writing
(w+) it does not have to already exist. If it doesn't exist, it will be created
and then opened.
if ((myfile1 = fopen("afile1", "r")) == NULL)

{

if ((myfile1 = fopen("afile1", "w+")) == NULL)
