C program for Bubble Sort

Today I am going to share how to perform bubble sort in C programming language. What is Bubble Sort? Bubble sort is a very simple sorting algorithm which compares consecutive numbers and swap them if both are not in right order. This gives the biggest element at the end in each inner loop cycle. Here is an animated example for bubble sort:

#include
#include

  void bubbleSort(int arr[],int length)
  {
        int i,j,temp;
         for(i=length;i>0;i--)
         {
            for(j=0;j<=i;j++)
   { 
                if(arr[j]>arr[j+1])
                { 
//swap if previous value is bigger then next value
                    temp=arr[j];
     arr[j]=arr[j+1];
                    arr[j+1]=temp;
                }
   }// End of Inner For loop
        }// End of Outer For loop.
  }// End of BubbleSort Function
  


 void main()
 {

  
  int data[] = {4,3,5,2,9,2,1,8,7,0}
  int i;

  clrscr();

  printf("\nData before sorting: ");
  
  for( i=0; i<10; i++)
  { 
   printf("%d , ",data[i]);
  }
       
  bubbleSort(data,10);

  printf("\nData after sorting: ");
  
  for( i=0; i<10; i++)
  {
   printf("%d , ",data[i]);
  }
  
  } //End of this example.

C Program to Swap Two Numbers

It is a sample c program to swap two number.

printf("\n Enter value of a:-");
scanf("\n%d",&a);
printf("\n Enter value of b:-");
scanf("\n%d",&b);
printf("\n\n a before swapping is:--%d",a);
printf("\n\n b before swapping is:--%d",b);
swap(a,b);
printf("\n\n a after swapping is:--%d",a);
printf("\n\n b after swapping is:--%d",b);
getch();

}

C Program to Check String is Palindrome or Not

It is a sample C language example. It is a string palindrome program which accept a string from user.
It checks that accepted string is a palindrome string or not. If string or string reverse is as same as then this string is a palindrome string. It means read string same in both forward or backward direction.

Aim - C program to check whether the accepted string is palindrome or not.

Program Source Code

//C Program to check accepted string is palindrome or not
#include"stdio.h"
#include"conio.h"
int isPallindrome(char *);
void main()
{
  int a;
  char str1[30];
  clrscr();
  printf("\n******String Palindrome******\n");
  printf("Enter a string: ");
  gets(str1); // accept string from user
  a=isPallindrome(str1);  /*function calls, accept string as argument and return flag value*/

  if(a)
   printf("\nstring: %s is a palindrome string",str1);
  else
   printf("\nstring: %s is not a palindrome string",str1);
  getch();

}


int isPallindrome(char *str2)
{
   int i,j,flag=1;

   for(i=0,j=strlen(str2)-1; i<j; i++, j--)
 {
    if(str2[i]!=str2[j]) /*starts checking from ends of string to middle*/
  {
    flag=0; /*if reverse of string is not same than return 0*/
    break;
  }

 }
   return(flag);
}

Output1
******String Palindrome******
Enter a string: MADAM
string: MADAM is a palindrome string

Output2
******String Palindrome******
Enter a string: HELLO
string: HELLO is not a palindrome string

C Program For Fibonacci Series

Hello everybody I want to discuss about How to generate a Fibonacci series in C programming.

What is Fibonacci Series?

The first two Fibonacci numbers are 0 and 1 then next number is addition of previous two numbers.

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89.....
In mathematics it is defined by recurrence relation.

Program Code

  


//C Program for generate Fibonacci series
#include "stdio.h"
#include "conio.h"
void main()
{
 int a,b,c,i,n;
 clrscr();
 a=0;
 b=1;
 printf("\n enter n for how many times generate series");
 scanf("%d",&n);
 printf("\n FIBONACCI SERIES\n");
 printf("\t%d\t%d",a,b);
for(i=0;i<n;i++)
{
     c=a+b;
     a=b;
     b=c;
     printf("\t%d",c);
 }
