Topic 1: the student achievement management system
Some classes have no more than 100 people (concrete Numbers from the keyboard input) take a certain course of examination, programming implementation, such as
Under the function of student achievement management system: (with a structure array)
(1) entry each student's student id, name and test scores;
(2) the calculation course of total peace divide;
(3) the output of each student's student id, name, the examination results;
(4) according to the results from high to low discharge league table; Sorting algorithm (self-study)
(5) by student number query students ranking and test scores,
Among them: (1), (2), (3) to do, (4), (5), encourage the calling function and file, implementation phase
The bonus should be content,
