Try to give examples. 4. Please write down the serial number of the question before attempting it. Q Q Q3 Q4 Define a class Library with the following members: DATA MEMBER TYPE Issue_date Character Id Integer Author Character MEMBER FUNCTION Input( ) is accepting values of Issue_date,Id,Author from user. Display( ) is displaying values of Issue_date, Id,Author from user. a) Write a function FIND( ) to check whether n(accepted as parameter) is even or odd and returning - if n is even or 0 if n is odd. b) Write a program to convert uppercase alphabet to lowercase alphabet.(do not use standard library function to perform the following task). c) Write a program to reverse a number n, where n is accepted from user. d) Write a program to find the sum of first n natural numbers,where n is accepted from user. e) Write a program to accept and display details(emp_id,emp_name,salary) of 30 employees from user,using structures. f) Write function prototype for the following: i. A function FIND( ) accepting an integer, a character and returning reference to an integer. ii. A function VAR( ) accepting integer pointer, reference to a character and not returning any value. iii. A function DURATION( ) accepting a constant integer and returning structure variable of structure TIME. a) Which operator is used to access/reference structure elements? b) Write an appropriate C++ statement to redefine float as amount type. c) Explain the concept of call by value and call by reference in detail. d) Initialize the following structure with valid values: Struct travel int id; char to[0]; char from[0]; float price; ; e)change the following For. Loop structure to while loops for (j=;j<=0;++j) for(k=0;k>=;--k) cout<<j*k; cout<< computer science ; Find the output of the following code(assuming that the required header files have been included in the code): (a) 5= =0 XI of 4
