Question

Create a structure to specify data on students given below: Roll number, Name, Department, Course, Year of joining Write an array of 10 students in the collage. Write two functions; one for input, second for output and determine following in main() (a) write a program to print names of all students who joined in a particular year. (b) Write a program to print the data of a student whose roll number is given assignment

Answer 1

#define _CRT_SECURE_NO_WARNINGS //runtime complie
#define SIZE 3 //size of array
#include <stdio.h>//standart input output
#include <stdlib.h>//standart lib
#include <string.h>//libraru for string function and ...
#include <malloc.h>
//Imnplement structure Student
