[Solved] Can anyone explain me the working of this C code? [duplicate]

Question

printf format string %.*s takes two arguments, * for the number and finally s for a string, so it prints the first 7 characters of the string pointer s. In general, anytime there is a number, you may use * instead to read it as an argument.

%7s would print seven characters or more if the string were longer, while %.7s would print up to seven characters. So sometimes one would write "%*.*s", 7, 7, s to print exactly 7 characters.
