Reading long int using scanf

Question

To read an int using scanf we use:

scanf(\"%d\", &i);

What if i is a long not int??

Answer 1

scanf("%ld", &i);

You can also use "%Ld" for a long long (and depending on your compiler, sometimes also "%lld").

Take a look at the Conversions section of the scanf man page for more. (Just Google it if your system doesn't have manpages).
