Include functions as specified in the code template to perform the following operations.
1)Display names of students from a particular year
2)Display names of students from a particular department
3)Display all details of the student having the highest CGPA
4)Display all details of the student from a particular department having the highest CGPA
5)Display all details of a particular student (Search by name)
6)Display all details of all students
7)Update CGPA of a particular student [Update CGPA by 0.5 of the particular student]
8)Exit
Create a structure named Student.
struct Student
{
char name[30];
char department[20];
int yearOfStudy;
float cgpa;
};
Please note that whenever multiple records are displayed, they are displayed sorted in ascending order based on the name.
Function Specification:
void dispStudentNamesfromYear(struct Student *s, int year, int n)
void dispStudentNamesfromDept(struct Student *s, char *dept, int n)
void dispStudentHighestCGPA(struct Student *s, int n)
void dispStudentHighestCGPAfromDept(struct Student *s, char *dept, int n)
void dispStudentDetailsbyName(struct Student *s, char *name, int n)
void dispStudentDetails(struct Student s)
void updateCGPA(struct Student *s)
