How to make cin take only numbers

Question

Here is the code

double enter_number()
{
  double number;
  while(1)
  {

        cin>>number;
        if(cin.fail())
        {
            cin.clear()         


        

Answer 1

I would prefer the following code. Among many codes to clear this question out of our minds, I think this is most appropriate code I found online.

#include 
#include 
using namespace std;

int main(){
    int n;
    while(!(cin >> n)) {
        cin.clear(); // to clear the buffer memory
        cin.ignore(numeric_limits::max(), '\n');
        cout << "Please enter a valid integer!";
    }
    cout << "Your Integer: " << n << endl;
    return 0;
}
