Question

Using C++

The main purpose of this lab is to create functions using call-by-value and call- by-reference parameters.

Activity #1

The first activity will be to write a function that sort an array of numbers (passed as a parameter) in ascending order. The input and output for the program are as follows:

Input/Output:

Enter 5 integers: 1 23 4 54 3

The array of integers sorted in ascending order is: 1 3 4 23 54

Include a function swapper(int& a, int& b) that can be used in your sort function. Save the source code in a file named assignment1.cpp.

Activity #2

Once you have completed the first activity, you should modify the program created in Activity #1 to take randomly generated input instead of command-line input. Save the source code in a file named assignment2.cpp.

Use the “time” command to detect how long it takes to sort 1000 numbers and 10,000 numbers. Include the time result as a comment in your program

Explanation / Answer

#include<iostream>
using namespace std;

// function that swaps 2 numbesr
void swapper(int& a, int& b)
{
int temp = a;
a = b;
b = temp;
}

main()
{
// declaring variables
   int fiveInts[5], i, j;
   int n = 5;
  
// taking user input
   cout<<"Enter 5 integers: ";
   for(i=0; i<n; i++)
   {
       cin>>fiveInts[i];
   }
  
   // Bubble sort technique to sort elements
   for(i=0; i<(n-1); i++)
   {
       for(j=0; j<(n-i-1); j++)
       {
           if(fiveInts[j]>fiveInts[j+1])
           {
               swapper(fiveInts[j],fiveInts[j+1]);
           }
       }
   }
  
   // printing output
   cout<<endl<<"The array of integers sorted in ascending order is: ";
   for(i=0; i<n; i++)
   {
       cout<<fiveInts[i]<<" ";
   }
}

SAMPLE OUTPUT

#include<iostream>
using namespace std;

// function that swaps 2 numbesr
void swapper(int& a, int& b)
{
int temp = a;
a = b;
b = temp;
}

main()
{
// declaring variables
   int fiveInts[5], i, j;
   int n = 5;
  
// taking user input
   cout<<"Enter 5 integers: ";
   for(i=0; i<n; i++)
   {
       cin>>fiveInts[i];
   }
  
   // Bubble sort technique to sort elements
   for(i=0; i<(n-1); i++)
   {
       for(j=0; j<(n-i-1); j++)
       {
           if(fiveInts[j]>fiveInts[j+1])
           {
               swapper(fiveInts[j],fiveInts[j+1]);
           }
       }
   }
  
   // printing output
   cout<<endl<<"The array of integers sorted in ascending order is: ";
   for(i=0; i<n; i++)
   {
       cout<<fiveInts[i]<<" ";
   }
}

SAMPLE OUTPUT

  Enter 5 integers:  4 5 6 3 2    The array of integers sorted in ascending order is: 2 3 4 5 6
