2. Write a C++ program to show the sorting methods based on input by the user. You can choose any TWO (2) of the sorting methods as follow:
− Selection
− Insertion
− Merge
− Bubble
− Quick
//bubble sort
#include<iostream>
using namespace std;
int main()
{
int n, i, arr[50], j, temp;
cout<<"Enter the Size (max. 50): ";
cin>>n;
cout<<"Enter "<<n<<" Numbers: ";
for(i=0; i<n; i++)
cin>>arr[i];
cout<<"\nSorting the Array using Bubble Sort Technique..\n";
for(i=0; i<(n-1); i++)
{
for(j=0; j<(n-i-1); j++)
{
if(arr[j]>arr[j+1])
{
temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
}
}
}
cout<<"\nArray Sorted Successfully!\n";
cout<<"\nThe New Array is: \n";
for(i=0; i<n; i++)
cout<<arr[i]<<" ";
cout<<endl;
return 0;
}
//Selection sort
#include<iostream>
using namespace std;
int main()
{
int i,j,n,loc,temp,min,a[30];
cout<<"Enter the number of elements:";
cin>>n;
cout<<"\nEnter the elements\n";
for(i=0;i<n;i++)
{
cin>>a[i];
}
for(i=0;i<n-1;i++)
{
min=a[i];
loc=i;
for(j=i+1;j<n;j++)
{
if(min>a[j])
{
min=a[j];
loc=j;
}
}
temp=a[i];
a[i]=a[loc];
a[loc]=temp;
}
cout<<"\nSorted list is as follows\n";
for(i=0;i<n;i++)
{
cout<<a[i]<<" ";
}
return 0;
}
