C program for Bubble Sort | C Program Examples

  
#include<stdio.h>
#include<conio.h>

  void bubble(int a[],int n)
  {
        int i,j,t;
         for(i=n-2;i>=0;i--)
         {
            for(j=0;j<=i;j++)

                  {
                    if(a[j]>a[j+1])
                                    {
                                      t=a[j];
                                     a[j]=a[j+1];
                                     a[j+1]=t;
                                    }
                   }
       

           }//end for 1.

  }//end function.


  void main()
  {

      int a[100],n,i;

      clrscr();

      printf("\n\n Enter integer value for total no.s of elements to be sorted: ");
      scanf("%d",&n);

      for( i=0;i<=n-1;i++)
            { printf("\n\n Enter integer value for element no.%d : ",i+1);
              scanf("%d",&a[i]);
            }

       bubble(a,n);

       printf("\n\n Finally sorted array is: ");
       for( i=0;i<=n-1;i++)
       printf("%3d",a[i]);

  }

Output will be as Following

Enter integer value for total no.s of elements to be sorted: 6
Enter integer value for element no.1 : 89
Enter integer value for element no.2 : -4
Enter integer value for element no.3 : -67
Enter integer value for element no.4 : 5
Enter integer value for element no.5 : 78
Enter integer value for element no.6 : 11

Finally sorted array is: -67 -4 5 11 78 89

Why use break statement inside switch case in C

The typical case with switch-case conditional statements is that when a case gets executed the switch-case condition doesn't stop its execution at that point rather it executes all the subsequent cases following the case which is executed first. Lets take a look at an example to understand this concept.
