Sunil Shah, I think you're talking of formatted output in C, right?

printf("%s", "word");

means that you insert the string (s) at the spot of the %.

printf("%5s", "word");

says how wide this entry will be within the string (in letters).

Compare:

printf("%s", "x");

leads to the output

x

while printf("%5s", "x")

would look like this:

x <-- 4 spaces from the left
