4 Q5.i) Name the keywords which are optional in switch-case. [1] ii) Name two operators that work as unary and as well as binary operator. [1] iii) What is an entry controlled loop?name one entry controlled loop of C++. iv)what is a syntax error? When is (are) syntax error(s) detected? v) What is a comment? With suitable examples show two ways of writing comment. vi) What is type casting? With suitable examples show two ways of using type casting. Q6 a) In the program segment given below, replace if- by switch-case and ternary operator: int x, y, lo; cout << "Input two integer values? "; cin >> x >> y; if (x <= y) lo = x; lo = y; cout << "Minimum Value = " << lo << endl; b) In the program segment given below, replace if- by switch-case and conditional operator: int year; cout << "Input Year? "; cin >> year; if (year % 4 == 0 && year % 100!=0) cout << year << " Leap Year"; cout << year << " Not Leap Year"; Q7. Define Local variable. Give a suitable example of a Local variable. Mentionany two(2) characteristics of a Local variable. Q8 What is the use of keyword const in a C++ program? How is it differ from #define Q9.a) Differentiate between function prototype and function definition with a suitable example. b)differentiate between Actual and Formal parameter with a suitable example c) Differentiate between Value and Reference parameter with a suitable example Q10 a)why do we need return statement in a C++ function? b)what is the advantage of having a C++ function with default parameter? Q11a) Define string. What happens when you display an array name on the screen? b) Define Open Array? Give two uses of Open Array Q12a)Generate and display all the Prime numbers between 2 and n (including 2 and n), where n ispassed as a parameter to the function. Return value of the function is void. Name of the function is genprime(). b) Write a program which initialized FaipsKuWait to an array of character name stringand convert lowercase letter to uppercase and uppercase to lowercase. Display the string after conversion Such that final output will be faipskuwait XI/FinalTerm/SamplePaper-1 Page 4

5 Q13a ) Suppose marks1, marks2 and marks3 are three arrays of double of size n1, n2 and n1+n2 respectively. The arrays marks1 and marks2 are sorted in descending order. Write C++ function to produce third array marks3 by merging marks1 and marks2. The array marks3 appear in descending order. Use the function declaration given below for merging: void merging(double[], double[], double[], int, int); [4] b) Write a C++ function to delete an element in an array of integers. Array name, number of elements currently in the array and position for deletion is passed as parameter. Return value of the function is void. c) Write a C++ function to display the sum of all even numbers at even position and product of all odd numbers at odd position of an element in an array of integers. Array name, number of elements currently in the array is passed as parameter Return value of the function is void. d) Write a function to find whether a string pass as parameter is Palindromic String or not and display Q14 Answer the following question based on structure [3 x 5=15] struct bank int accno; //account number char name[20]; //account holder name char actype; //account type either CA or SA double balance; //balance ; i) Write a C++ function to sort an array of bank on accno by using selection sort. Array name and number of elements in the array are passed as parameters to the function. Return value of the function is void. ii) Write a C++ function to sort an array of bank on accno by using insertion sort. Array name and number of elements in the array are passed as parameters to the function. Return value of the function is void. iii) Write a C++ function to sort an array of bank on name by using bubble sort. Array name and number of elements in the array are passed as parameters to the function. Return value of the function is void. iv) Write a C++ to search for a name in a sorted array of bank (sorted on name) by using binary search. Array name and number of elements in the array are passed as parameters to the function. Name that is to be searched is a local variable. Return value of the function is void. v) Write a C++ to search for an account number in an array of bank by using linear search. Array name and number of elements in the array are passed as parameters to the function. Account number that is to be searched is a local variable. Return value of the function is void.
