Problem : Student Details, Sort, Search,.cpp

/*Implement the following functions to access the details of a particular student from a list of n students. Use three functions as follows.
a. Get the details of n students.
i. Roll number
ii. Name
iii. Programme
iv. CGPA
b. Sort the list based on their roll number
c. Search for a particular student’s details. (Use minimum number of comparison)*/
