Abstract:

C Programming Language  courses is a compulsory public basic course to science and engineering majors in the first year of college.Array application is the teaching focus of C Programming Language.An array is a common form of data stored in a computer's memory,and it is also the basis for many applications to achieve their functionality,performance and other aspects to meet their needs.Sorting algorithm is a typical application of the array.Based on many years of teaching experience,we explore the teaching methods for array application teaching,analyze the bubble sort algorithm and selection sort algorithm implementation process,and make a comparison between the two algorithms through layers of progressive teaching methods.

Key words: program design；array；array application；bubble sort algorithm；selection sort algorithm； function definitions
