A Palindrome String is a String that remains the same when its character are reversed. Like saas, for example: we take saas and reverse it, after revers it is same as original.
Steps to write program
- Get the string from user.
- Reverse it.
- Compare it with the string entered by the user.
- If both are same then print palindrome
- Else print not a palindrome.
Program to Check String is Palindrome or not in C++
#include<iostream.h> #include<conio.h> void main() { int i,j,len,flag=1; char a[20]; cout<<"Enter a string:"; cin>>a; for(len=0;a[len]!='\0';++len); for(i=0,j=len-1;i<len/2;++i,--j) { if(a[j]!=a[i]) flag=0; } if(flag==1) { cout<<"\nString is Palindrome"; } else { cout<<"\nString is not Palindrome"; } getch(); }
Output
Enter a String: saas String is Palindrome
Check String is Palindrome or not in C++
#include<iostream.h> #include<conio.h> #include<string.h> #include<stdio.h> void main() { char str[10]; int i,j,n,flag=0; cout<<"Enter any string:"<<endl; gets(str); n=strlen(str); for(i=0,j=n-1;i<=n/2;i++,j--) { if(str[i]!=str[j]) flag=1; break; } if(flag==1) { cout<<"String is not Palindrome"; } else { cout<<"String is Palindrome"; } getch(); }
Output
Enter any String: lol String is Palindrome
