[Error] return-statement with no value, in function returning ‘int’ [-fpermissive]:grin:

#include <bits/stdc++.h>
#include <string.h>
using namespace std;
int main()

int t;

while(t--)

    char str[100];

write return 0 instead of return here.

3

no return 0 terminates the program there only

4

Use break then(if you just want to break out of the loop) .

5

no not working

Yeah, it won’t. Coz you have messed up many things. Firstly, use #include <bits/stdc++.h>. This helps you avoid missing out on important headers. For example, you are using std::cin
here when you haven’t included iostream header. Also, you can’t take input char arrays in that manner. (Use std::string) instead. Thirdly, learn to Google wisely. (The most important point) .

thank you sir for your time no disrespected but some points to say if you dont mind
1)it was not showing here but i have used bits/stdc++ header file.there was no problem with that.
2)i figured out that else
cout<<"wins"<<endl;
was in wrong place which resolved my problem.there was nothing about taking arrays in diff way.
3)learn to Google wisely. i dont get that point.
i appreciate your responses thank you

#include<iostream>

using namespace std;
int main()
{
string s;
cin>>s;

//METHOD 1

bool isPalindrome=true;
int n = s.size();
for(int i = 0; i < n/2; i++)
{
	if(s[i]!=s[n-i-1])
	{
		isPalindrome=false;
	}
}
if(isPalindrome == true)
{
	cout<<"Palindrome\n";

}
else{
    cout<<"Not Palindrome\n";
}

//optimizing method 1 

int n = s.size();
for(int i = 0; i < n/2; i++)
{
	if(s[i]!=s[n-i-1])
	{
		cout<<"Not Palindrome\n";
		return 0;
	}
}

	cout<<"Palindrome\n";
return 0;

}

HOPE THIS HELPS :wink:
