Lab Week 14
Q no 1
Create a function called swaps () that interchanges the values of the two
arguments sent to it. (You will probably want to pass these arguments by
reference.) Make the function into a template, so it can be used with all numerical
data types (char, int, float, and soon). Write a main () program to exercise the
function with several types.
Q No 2:
Create a function that accept and swap the values of the array using template
function.
Q no 3:
Write program that create a Stack with exception handlings methods.
Q no 4: Write program that create a Stack with multiple catch blocks one for full
Stack and second for empty Stack exception handlings methods
Write a function calculateAverage() which takes four int arguments which
are marks for four courses in the semester and returns their average as a
float.
The calculateAverage() function should take only valid range for marks
which is between 0 - 100. If the marks are out of range throw an
OutOfRangeException - define this exception as a class
Solved examples for exception handling
#include <iostream>
using namespace std;
class OutOfRangeException {};
/*
* Pre conditions: all the four marks must be between
* 0 -100 otherwise the function throws a OutOfRangeException
* Post condition: returns the average of the four marks
* Invariants: avg >= 0 && avg <=100
*/
float calculateAverage(int m1, int m2, int m3, int m4) {
if ((m1 < 0 || m1 > 100))
throw OutOfRangeException();
if (m2 < 0 || m2 > 100)
throw OutOfRangeException();
if (m3 < 0 || m3 > 100)
throw OutOfRangeException();
if (m4 < 0 || m4 > 100)
throw OutOfRangeException();
return (m1 + m2 + m3 +m4 ) / 4.0;
}
