A palindrome is a string, integer number or another sequence of characters that reads the same backward as forward, such as madam or racecar or the number 76567. If we read madam from the front or back side then the spelling and pronunciation are same i.e. nayan=nayan. The actual code for the palindrome string is as follows:   



C language code for Palindrome string:

#include <stdio.h>om

#include <string.h>

void main()

{

  char a[100], b[100];

  clrscr();

  printf("Enter a string to check if it is a palindrome:\n");

  gets(a); //to accept the string from user



  strcpy(b,a);  // Copying input string

  strrev(b);  // Reversing the string by inbuild function strrev()



  if (strcmp(a,b)==0)  /* Comparing input string using

  inbuild function strcmp() with the given reverse string*/



  printf("The string is a palindrome.\n");/* when if condition

  is satisfy or true */


  else

    printf("The string is not a palindrome.\n");/* when if condition

    is not satisfy or false */

  getch();

}

------------------------------------------------------------------------------

Output:

Enter a string to check if it is a palindrome:

asdfdsa

The string is a palindrome.

SIMPLE CPP LANGUAGE CODE FOR ADDITION OF TWO NUMBERS:

#include<iostream.h>
#include<conio.h>
void main()
{int a, b, c;//we take two integer value
cout<<"Enter the number :";//use to print the letter, character
cin>>a>>b;//use to accept number
c=a+b;//arithmetic logical operation, formula
cout<<"Ans="<<c; /*use to perform operation and display answer*/
getch();
}

And save with extension .cpp
for eg.
add.cpp//add is the name of the file and .cpp is extension of file.
           In the above example, we can add integer numbers not fractional numbers. for example when the output screen comes type two numbers like 2 and press enter then type next numbers like 6 then press enter the answer will be displayed on the output screen.
            This code is for integer numbers, if we want to add fractional numbers then in above code small changes is there i.e.in the place of int type float.For addition of fractional numbers the code is as follow:

ADDITION OF TWO FRACTIONAL NUMBERS:
#include<iostream.h>
#include<conio.h>
void main()
{flaot a, b, c;//we take two fractional value
cout<<"Enter the number :";//use to print the letter, character
cin>>a>>b;//use to  accept number
c=a+b;//arithmetic logical operation, formula
cout<<"Ans="<<c; /*use to perform operation and display answer*/
getch ();
}

     In the previous blog, I said that many types of comment is there in that other type is
/*        comment         */  .This is used to give the multiline comments for example.
cout<<"Ans="<< c;/*use to perform operation and display answer*/
