C++ outputs strange symbols instead of text entered from the keyboard. The message "Введите слово" displays correctly, the number of letters is also correctly counted, and then something happens to the word, incomprehensible characters are displayed instead, and as a result the program does not work correctly (the problem is the same with Cyrillic, Latin, and numbers ".

using namespace std;
char a[1][50];
int lenght, i, j, f = 0;
int main() {
setlocale(LC_ALL, "rus");
cout << "Введите слово\n";
cin >> a[1];
lenght = strlen(a[1]);
cout << "Длина слова: " << lenght << endl;
cout << a[1] << endl;
for (j = 0; j <= lenght; j++) {
if (a[1][j] == a[1][lenght - j]) continue;
else {
f = 1;
break;
}
}
if (f == 0) cout << "Введенное слово является полиндромом";
else cout << "Введенное слово не является полиндромом";
