Sorting Programs

Bubble Sort 

write a program to implement code for simple bubble sort using array  in c programming language

#include<stdio.h>

int main(){

  int s,temp,i,j,a[20];

  printf("Enter total numbers of elements: ");

  scanf("%d",&s);

  printf("Enter %d elements: ",s);

  for(i=0;i<s;i++)

      scanf("%d",&a[i]);

  //Bubble sorting algorithm

  for(i=s-2;i>=0;i--){

      for(j=0;j<=i;j++){

           if(a[j]>a[j+1]){

               temp=a[j];

              a[j]=a[j+1];

              a[j+1]=temp;

           }

      }

  }

  printf("After sorting: ");

  for(i=0;i<s;i++)

      printf(" %d",a[i]);

  return 0;

}

Selection sort

write a program to implement code for Selection sort using array in c programming language

#include<stdio.h>

int main(){

  int s,i,j,temp,a[20];

  printf("Enter total elements: ");

  scanf("%d",&s);

  printf("Enter %d elements: ",s);

  for(i=0;i<s;i++)

      scanf("%d",&a[i]);

  for(i=0;i<s;i++){

      for(j=i+1;j<s;j++){

           if(a[i]>a[j]){

               temp=a[i];

              a[i]=a[j];

              a[j]=temp;

           }

      }

  }

  printf("After sorting is: ");

  for(i=0;i<s;i++)

      printf(" %d",a[i]);

  return 0;

}

 Insertion Sort

write a program to implement code for simple insertion sort using array in in c programming language

#include<stdio.h>

int main(){

  int i,j,s,temp,a[20];

  printf("Enter total elements: ");

  scanf("%d",&s);

  printf("Enter %d elements: ",s);

  for(i=0;i<s;i++)

      scanf("%d",&a[i]);

  for(i=1;i<s;i++){

      temp=a[i];

      j=i-1;

      while((temp<a[j])&&(j>=0)){

      a[j+1]=a[j];

          j=j-1;

      }

      a[j+1]=temp;

  }

  printf("After sorting: ");

  for(i=0;i<s;i++)

      printf(" %d",a[i]);

  return 0;
