C-language linked list __c language

Title: Enter the information of several students (including school number, name and grade), enter the end of the input number is 0 o'clock. Establish a one-way linked list, and then enter a score value, the result is greater than equal to the value of the student information output.

Input:3n+2 line, every 3 acts a student's information, respectively, is the study number, name and result. The penultimate act of 0 indicates the end of the input. The last behavior is an integer that represents the score.

Output: Several lines, each three lines represent a student's information.
