Question

How many times does the DO loop execute for the first iteration of the DATA step?

data work.compare(drop=i);
set finance.cdrates;
Investment=5000;
do i=1 to Years;
Investment+Rate*Investment;
end;
run;
a. 1
b. 5
c. 3
d. 4

Answer 1

The DO loop in the SAS DATA step will execute as many times as the value of the 'Years' variable for each iteration of the DATA step. Without knowing the value of 'Years', we cannot provide a specific count of DO loop executions.

Step-by-step explanation:

The question relates to the execution of a DO loop within a DATA step in the SAS programming language. For the first iteration of the DATA step, the DO loop will execute a number of times equal to the value specified in the

Years variable, since the loop is constructed as do i=1 to Years;. Without additional context, such as the value of the Years variable, we cannot definitively determine the number of executions. However, if we assume that Years has a value, the DO loop will execute that many times. If Years equals to 1, then the answer would be (a) 1. If Years is 5, then it would be (b) 5, and so on for other values.
