On the morning of May 10, 2021, the open course of Program Design (C Language) was held in Classroom 709, Sanjiang Building, School of Computer Science and Communication Engineering. This open class is open to 91 students of chemistry major in 2020, and is lectured by Teacher Cheng Jing, who won the first prize of the 10th Teachers' Teaching Competition of Jiangsu University in 2020. Some teachers of schools and colleges participated in the teaching observation.

Mr. Cheng first led the students to review the basic concept of function and its definition form, and then introduced function parameters and function values as well as some function calls, such as nested function calls, recursive function calls.

The programming (C language) writing, this course contains a lot of code to the teacher in teaching process, to explain the logical train of thought, after drawing graphics easy understanding, finally on the PPT show the code in the form of the difficult points, key told students picking broken, and with the help of a distinctive teaching AIDS to deepen students' understanding, It's great for understanding the logic behind the code.
