13 . ( TCO 8 ) Many algorithms require direct communication from users . These types of algorithms are called _____. ( Points : 4 )
14 . ( TCO 9 ) What type of error occurs when an array subscript ’ s value goes beyond the total number of elements in the array ? ( Points : 4 )
15 . ( TCO 2 ) What type of variable can be accessed by any module within the design ? ( Points : 4 )
1 . ( TCO 10 ) A department store is having a customer appreciation sale . Depending on the total dollars purchased , the customer could receive a discount on total purchases . You are to develop pseudocode that will obtain the total dollars purchased from the user , determine the discount percent , and display the total amount due . When the purchases are more than $ 500 , the discount is 10 %. When the purchases are $ 500 or less , the discount is 6 %. ( Points : 10 )
2 . ( TCO 10 ) A small business in your neighborhood would like an application developed that determines the average dollar amount spent for every three purchases . The user will enter three different purchase amounts . You need to display the average to your client . Complete the pseudocode to design your logic . ( Points : 10 )
3 . ( TCO 9 & 10 ) There is a logic error in the following pseudocode . What statement ( s ) would you need to add to correct the logic ? Be sure to explain why you are adding the statements .
Set DOWHILE num <=> Set + num ENDO Display total ( Points : 10 )
4 . ( TCO 4 & 10 ) Complete the pseudocode by rewriting the algorithm . The design is determining the correct sales tax depending on the county identifying code . Counties with a number less than 7 have a 5 % sales tax . The 8-24 codes have a sales tax of 7 %. Codes above 24 have a sales tax of 9 %. The code is entered by the user .
