It should be noted that one could ignore the inner braces as long as the list matches the amount and type of things to be initialized. So we could write 2Dpoint A[100] = {0,0,255,20,40,255,0,255,40,20, ….}; Array of Struct Pointers In some applications, using an array of struct pointers may be useful. Therefore we can define an array of struct points as follows. 2Dpoint* A[100]; In this case ...

The conversion functions are used to convert string dates, such as 08/12/06, 12-8-2006, 12 Aug 06, 12aug2006 14:23, and 12 aug06 2:23 pm, to Stata dates. The conversion functions are typically used after importing or reading data. You read the date information into string variables and then these functions convert the string into something Stata can use, namely, a numeric Stata date variable ...

d. In different cases, it could do any of the above. C5. There are other ways of expressing uncertainty besides significant figures. For example, suppose a quantity is known to have a value between 20.4 and 20.0 and our best estimate of the value is midrange at 20.2. We could write the number as 20.2 +/- 0.2 and say that the number has a 1% ...

time that you would ignore, but it is better and easier to use a %td variable. In %td variables, 0 still corresponds to 01jan1960, but a unit change now represents an entire day rather than a millisecond. The value 1 represents 02jan1960. The value 1 represents 31dec1959. When you subtract %td variables, you obtain the number of days between dates. In a financial application, you might use ...
