    cout << "输入一个数: ";
    cin >> n;

    cout << "斐波那契数列: " << firstTerm << " + " << secondTerm << " + ";
    nextTerm = firstTerm + secondTerm;

    while ( nextTerm < n) {
        cout << nextTerm << " + ";
        nextTerm = firstTerm + secondTerm;
        firstTerm = secondTerm;
        secondTerm = nextTerm;
