This is the output from the second printf statement:

printf("Lion \t Elephant \n  Zebra");

Thus, the information in the Format String (the part
enclosed in double quotation marks) is literally printed
out as output.  In addition to words in the Format String,
there are two Escape Characters (\n and \t).

The \t causes a tab, in this case, after the word Lion. 

The \n causes a newline, in this case, after the word
Elephant.
