#print
(Section 1.5)
Write a program that will read the first character
from its input and print it out in octal.
Compile it, test it, and then type ready.
#once #create Ref
+
#user
a.out <Ref >test
grep 53 test >/dev/null
#succeed
A possible solution:
main()
{
printf("%o\n", getchar());
}
Remember that you can use a function value almost
any place that you could use a variable like x.
Thus many times there's no need for extra variables.

#next
