Problem in solving CODETOWN problem

My issue

The online compilation is showing different results than GCC. I wrote the solution for this problem and it was showing “Wrong Answer”. I was trying to find the error with my code, and after half an hour I got to know that the answer for the testcase “CODETOWN” is different in my GCC(which was showing it correct btw) and the online IDE on codechef. Can anyone help?
This actually wasted a pretty big chunk of my time and it is not acceptable in contests. If anyone could have a look into this, it would be grateful and appreciated

My code

#include <iostream>
#include <cstring>
#include <cctype>
using namespace std;

bool isvowel(char ch) { 
	if ((ch == 'A') || (ch == 'E') ||(ch == 'I') ||(ch == 'O') ||(ch == 'U'))
		return 1;
	else
		return 0;
}

int main()
{
	int t;
	cin >> t;
	for (int i = 0; i < t; ++i) {
		char s[8];
		cin >> s;

			int c = 0;
			for (int i = 0; i < 8; ++i) {
				if (i == 1 || i == 3 || i == 5) {
					if (isvowel(s[i])) {
						c++;
					}
				}
				else {
					if (isvowel(s[i]) == 0) {
						c++;
					}
				}
			}

			if (c == 8) {
				cout << "YES" << endl;
			}
			else {
				cout << "NO" << endl;
			}
	}
	return 0;
}

for (int i = 0; i < 8; ++i) {
if (i == 1 || i == 3 || i == 5) {
if (!isvowel(s[i])) { // Changed condition here
c++;
}
}
else {
if (isvowel(s[i]) == 0) {
c++;
}
}
}

Now, the condition if (!isvowel(s[i])) checks if the character at positions .

BUT aren’t the characters at these places i.e. 1,3 and 5 supposed to be vowels why would u check them to be non vowels. can anyone explain?

Yea exactly, the solution provided by @menaria would not work in this case
