What are the resulting values for the macro variables that are defined here? %let month1 = June; %let month2 = July; %let period1 = &month1&month2; %let period2 = May&month1; %let period3 = &month2.Aug;

technology programming languages

  1. month1 June month2 July period1 June July period2 May June period3 July Aug

  2. month1 June month2 July period1 JuneJuly period2 MayJune period3 July.Aug

  3. month1 June month2 July period1 JuneJuly period2 MayJune period3 JulyAug

  4. month1 June month2 July period1 junejuly period2 Mayjune period3 julyaug

Show answer
Correct Option: C
Explanation:

To understand the resulting values for the macro variables, we need to know that the ampersand (&) is used to reference the value of a macro variable. The resulting values for the macro variables are:

  • %let month1 = June; (the value of month1 is "June")
  • %let month2 = July; (the value of month2 is "July")
  • %let period1 = &month1&month2; (the value of period1 is "JuneJuly")
  • %let period2 = May&month1; (the value of period2 is "MayJune")
  • %let period3 = &month2.Aug; (the value of period3 is "July.Aug")

Therefore, the answer is:

The Answer is: C

%let lib=sasuser; %let year=02; %let month=jan; libname &lib ’SAS-data-library’; proc print data=&lib.y&year&month; run; The dataset name that proc print gets is "sasusery02jan".Which of the following character you will use in place of to finally have "sasuser.y02jan" dataset. proc print data=&lib.y&year&month; run;

technology programming languages

  1. . (period)

  2. &(ampersand)

  3. %(percentage)

  4. Any one of the above character

Which of the following correctly produces a title in which the current date is left justified in order to remove extra blanks?

technology programming languages

  1. title "Report for %sysfunc(left(%sysfunc(today(),worddate.)))";

  2. title "Report for %sysfunc(left(today(), worddate.))";

  3. title "Report for %sysfunc(left(%qsysfunc(today(), worddate.)))";

  4. title "Report for %left(today(), worddate.))";

Show answer
Correct Option: C

AI Explanation

To answer this question, you need to understand how to format a title in SAS using the %sysfunc function to manipulate the current date.

Let's go through each option to understand why it is correct or incorrect:

Option A) title "Report for %sysfunc(left(%sysfunc(today(),worddate.)))"; This option is incorrect because it uses an unnecessary nested %sysfunc function. The left function should be applied directly to the result of %sysfunc(today(),worddate.) to left justify it.

Option B) title "Report for %sysfunc(left(today(), worddate.))"; This option is incorrect because it does not use the proper syntax for the %sysfunc function. The %sysfunc function should be used with a specific SAS function, such as date. or left..

Option C) title "Report for %sysfunc(left(%qsysfunc(today(), worddate.)))"; This option is correct because it uses the %sysfunc function with the left function to left justify the result of %qsysfunc(today(), worddate.). The %qsysfunc function is used to resolve any potential macro quoting issues.

Option D) title "Report for %left(today(), worddate.))"; This option is incorrect because it does not use the %sysfunc function to manipulate the current date. The left function should be used within the %sysfunc function to left justify the result.

The correct answer is C. This option is correct because it properly uses the %sysfunc function with the left function and the %qsysfunc function to left justify the result of %qsysfunc(today(), worddate.).

Which of the following is an exclusive feature of C#?

technology programming languages

  1. Object Oriented

  2. IL

  3. XML documentation

  4. Garbage Collection

Show answer
Correct Option: C

AI Explanation

To answer this question, you need to understand the features of the C# programming language. Let's go through each option to understand why it is correct or incorrect:

Option A) Object Oriented - This option is incorrect because C# is an object-oriented programming language, but it is not an exclusive feature of C#. Many programming languages, such as Java and C++, are also object-oriented.

Option B) IL - This option is incorrect because Intermediate Language (IL) is not an exclusive feature of C#. IL is a common feature in languages that target the .NET framework, including C#.

Option C) XML documentation - This option is correct because XML documentation is an exclusive feature of C#. C# allows developers to document their code using XML comments, which can be used to generate documentation files.

Option D) Garbage Collection - This option is incorrect because garbage collection is not an exclusive feature of C#. Garbage collection is a memory management technique that is used in many programming languages, including C#.

The correct answer is C) XML documentation. This option is correct because XML documentation is a feature that is unique to C# and allows developers to document their code using XML comments.
