trying to prevent a char input

[fire child]

I'm trying to prevent an accidental char input but all my code does is repeat the error message.

string input = "";
stringstream myStream;
int hop;

while (true) 
  {
    stringstream myStream(input);
    cout << "What is the transmition range?" << endl;
    cin  >> hop;
    if (myStream >> input)
    break;
    cout << "Invalid entery, ";
  }

I think what you're trying to do is if (cin >>hop).

no that did not stop the repeating

[z05DSL3A]

std::string input = "";
    int number(0);

    while (true) 
    {
        std::cout << "What is the transmition range?" ;
        std::getline(std::cin, input);
   
        std::stringstream ss(input);
        if (ss >> number) 
            break;
        std::cout << "Invalid number, please try again" << std::endl;
    }
    std::cout << "You entered: " << number << std::endl;
