Each student performance information includes: student id, Chinese, maths, English, total score, the weighted average; A dynamic method to create an array used to store a number of student achievement information; Enter the student's student id, Chinese, maths, English, Calculate the score of students and weighted average (50% Chinese (30%), math, English 20%);
Output student achievement information,
New student performance information can be appended at the end of the array; Can according to the student number, delete the student performance information, can according to the student id or total score, ascending sort student achievement information,
