Practiced a small program of student information relationships:The functions involved are:1: Entry Score2: The ranking of the results3: Print out the results4: Find a certain score Sort the key points: bubble sort, outer loop each time is the number of cycles minus 1The inner loop is the internal cycle minus the number of outer loops minus 1, the principle can be reviewed before the blog Find key points: Locate the subscript for an array element and r

addition of records, delete records, modify records, search records, record sorting function. Better than before the place is mainly in the search records, record sorting. The lookup can be in multiple cases, and the sort is implemented by clicking the list header, in ascending and descending order, each column can be sorted. Because of the use of multiple recordsets, so in the implementation of the function of a lot of trouble, we can see the source program. After you've seen it, you may feel
