Question

What is the length of the Car_Type column created in this program?

data car_type;
set ;
if msrp>80000 then car_type="luxury";
else car_type="regular";
length car_type $ 8;
run;

a. 6
b. 7
c. 8

Answer 1

In the SAS program provided, the given LENGTH statement does not set the length of the Car_Type variable because it is placed after the assignment of values. Hence, the length will be 7, corresponding to the length of the value 'regular'.

Step-by-step explanation:

The question involves determining the length of the Car_Type column indicated in a SAS program. The correct answer can be derived from understanding how the LENGTH statement in SAS works.

In the SAS code provided, the LENGTH statement that assigns the length to car_type is placed after the assignment of values to car_type. However, in SAS, the LENGTH statement should be placed before any other statements that assign values to that variable to have the intended effect.

Therefore, the length of the Car_Type column will be the length of the longest value assigned to it before the LENGTH statement, which is 'regular' with a length of 7.
