Suppose you have to create a data structure to represent a "Student” where student is represented by "studid" whose data type is integer and "studname" whose data type is character array of size 40.

Question

_{Suppose you have to create a data structure to represent a "Student” where student is represented by "studid" whose data type is integer and "studname" whose data type is character array of size 40. You have decided to create a "Student" link}

_{list to store student information. Using the data type "Student" you, you need to create two students having their information as follows:}

_{1st- ID 1001 Name: ALEX}

_{2nd - ID=1002 Name: NICOLAS}

_{Define the data node "Student and allocate memory and create and show the link list of two students.​}
