C++ program to check whether the given string is Palindrome or not (3)

Palindrome:

Palindromes are words or phrases that read the same in both directions.

Some examples of common palindromic words: civic, dewed, deified, dad, mom, devoved, hannah, repaper, radar, level, rotor, kayak, reviver, racecar, redder, madam, redder, bob, pop, tot, malayalam, noon, rotator, rotavator, stats, solos, tenet and refer.

Program:
#include<iostream.h>
#include<conio.h>
#include<string.h>
void main()
{
char s[50],m[50];
int p=1,i;
clrscr();
cout<<"Enter the string: ";
cin>>s;
strcpy(m,s);
strrev(m);
for(i=0;i<=strlen(s)-1;i++)
{
if(*(m+i)!=*(s+i))
{
p=0;
break;
}
}
if(!p)
cout<<"\n"<<s<<" is not a Palindrome";
else
cout<<"\n"<<s<<" is a Palindrome";
getch();
}

Program to check whether the given number is Palindrome or not

#include<stdio.h>
void main()
{
int n, rev=0, rem,temp;
clrscr();
printf("Enter any number: ");
scanf("%d", &n);
temp=n;
while(temp!=0)
{
rem=temp%10;
rev=rev*10+rem;
temp=temp/10;
}
if(rev==n)
printf("%d is a Palindrome",n);
else
printf("%d is not a Palindrome",n);
getch();
}

Program to check whether the given string is Palindrome or not (2)

if(strcmp(a,b) == 0)
printf("\nThe string is a Palindrome");
else
printf("\nThe string is not a Palindrome");
getch();
}
