Sorting Programs

Store content in file,record of field - other file Calculate Total percentage Classfor each student Edit character Display pattern of numbers in reverse pattern Sescribes how to use Sort technique Declares data to the compiler Input record into file using extend mode Draw a line Use of Tables with INPUT clause Check student is pass or fail i/p result from user Calculate monthly sales amount -sequential access Create result statement for given semester Search name from file display roll no of student Generating julian date

Clause

Describe Functionality of Relative File Print addition of two nos and sum is third or not Use of perform verbs Bank Report depending upon user choice Reads in states until end of data Read student details from file - read operation Evaluates arithmetic expression - stores result Use of evaluate clause Describe use of IF CONDITION and PRINT Calculate Total percentage Class for each student Displays alphanumeric character in graphics mode Search perticular record Find age from accepted date from user Merge 2 files with students records Print presence report based on provided data Use of Inspect clause Check entered date is valid birth date or not Draws rectangle filled with one color
