If one of the fields in a struct is a statically declared array (like the name field in the studentT struct), the parameter gets a copy of the entire array (every bucket value). This is because the complete statically declared array resides within the struct, and the entire struct is copied over as a unit.
2000 Hours is a good estimate for the number of paid hours worked in a year. The per capita GDP is $52,839 (annually), and based on that the average person makes $26.42 per hour. An 8 hour day would get you $211.36 in a day. Keep in mind, however that this is the average income across the entire population.
According to a 2013 Bureau of Labor Statistics, or BLS, the average annual salary was $56,760. The average salary per hour was $27.29. This number may vary based on any number of factors, including general expertise, hours, tasks, and work environment.
