dev C++如何去掉string类型中的换行符?
replaceAll试过没用

int main()
{
    string str = "aaa\nbbbc\nttt\n";
    cout << str << endl;
    int find = 0;
    while (1)
    {
        find = str.find('\n', find);
        if (find == -1)
            break;
        str.erase(find, 1);
    }

    cout << str;

    return 0;
}
