C++ 查找整数：从 N 个整数中寻找给定的 X

#include <iostream>
using namespace std;

int main() {
    int n, x;
    cin >> n >> x;
    int a[n];
    for (int i = 0; i < n; i++) {
        cin >> a[i];
        if (a[i] == x) {
            cout << i << endl;
            return 0;
        }
    }
    cout << 'Not Found' << endl;
    return 0;
}
