In selection sort, the smallest value among the unsorted elements of the array is selected in every pass and inserted to its appropriate position into the array.The array is divided into two parts, first is sorted part, and another one is the unsorted part. Initially, the sorted part of the array is empty, and unsorted part is the given array. Sorted part is placed at the left, while the unsorted part is placed at the right.

//Selection Sort
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;
