C程序以结构体存储学生记录，并按姓名进行排序

{{ student_id = 1, student_name = nupur, student_percentage = 98}, { student_id = 2, student_name = Akash, student_percentage = 75}, { student_id = 3, student_name = Yash, student_percentage = 62}, { student_id = 4, student_name = Jyoti, student_percentage = 87}, { student_id = 5, student_name = Ramlal, student_percentage = 80}}

输出 − 学生记录 =

{{ student_id = 2, student_name = Akash, student_percentage = 75}, { student_id = 4, student_name = Jyoti, student_percentage = 87}, { student_id = 1, student_name = nupur, student_percentage = 98}, { student_id = 5, student_name = Ramlal, student_percentage = 80}, { student_id = 3, student_name = Yash, student_percentage = 62}}登录后复制
