What is %lu in C programming?
A printf format specifier follows the form %[flags][width][. precision][length]specifier . u is a specifier meaning “unsigned decimal integer”. l is a length modifier meaning “long”. The length modifier should go before the conversion specifier, which means %lu is correct.

What are the format specifiers in C programming?
The format specifiers are used in C for input and output purposes. Using this concept the compiler can understand that what type of data is in a variable during taking input using the scanf () function and printing using printf () function.
