int main(){
    string s;
    cin>>s;
    // write your code here......
    int a_times = 0;
    int b_times = 0;
    int c_times = 0;
    for (decltype(s.size()) i = 0; i < s.size(); ++i)
    {
        if (s[i] == 'a')
            ++a_times;
        else if (s[i] == 'b')
            ++b_times;
        else if (s[i] == 'c')
            ++c_times;
    }
    cout << a_times << " " << b_times << " " << c_times;
    return 0;
}

循环遍历即可
