(in c++)
Write a function named 'reverse' to reverse a string. Overload your function to reverse an
integer. The two functions have the same name. Write two more overloaded functions to return
true if the input (string or integer) is palindrome. Write a test program to prompt the user to first
enter a string and then a positive integer and determines if each of them is palindrome or not.
Solution
Reverse.cpp
#include <iostream>
#include <string.h>
using namespace std;
int reverse(char s[]);
int reverse(int n);
int main()
{
char s[100];
int n, flag, n1;
cout<<"Enter String :"<<endl;
cin >> s;
cout<<"Enter Number :"<<endl;
cin >> n;
flag = reverse(s);
if (flag) {
cout << s << " is not a palindrome" << endl;
}
else {
cout << s << " is a palindrome" << endl;
}
flag = reverse(n);
if (flag)
cout << "The number is a palindrome"<<endl;

else
cout << "The number is not a palindrome"<<endl;
return 0;
}
int reverse(char s[]){
int i, length;
int flag = 0;
length = strlen(s);
for(i=0;i < length ;i++){
if(s[i] != s[length-i-1]){
flag = 1;
break;
}
}
return flag;
}
int reverse(int n){
int n1, rev=0, r=0, flag = 0;
n1 = n;
do
{
r = n1%10;
rev = (rev*10) + r;
n1 = n1/10;
}while (n1!=0);
if(n== rev)
flag = 1;
return flag;
}
Output:
Enter String :
madam
Enter Number :
10001
madam is a palindrome
The number is a palindrome
Enter String :
abcde
Enter Number :
11124

abcde is not a palindrome
The number is not a palindrome
