We did not do any swapping,so all of the other elementsmust be correctly placed.
We can “skip” the last twopasses of the outer loop.
Program
void main(){ int arr[5],i,j,tem; cout<<“Enter Five Values”; for(i=0,i<5,i++) cin>>arr[i];
cout<<“The origanal values in array:\n”; for(i=0;i<5;i++) cout<<arr[i]<<“ “;
for(i=0;i<5;i++) for(j=0;j<4;j++)If(arr[ j ]>arr[ j+1 ]{ tem=arr[ j ]; arr[ j ]=arr[ j+1 ]; arr[ j+1]=tem;} cout<<“\n The sorted array: \n”; for(i=0;i<5;i++) cout<<arr[ i ]<<“ “; getch();}
