Answer 1

Hey BlooderDen :

Source :https://code.sololearn.com/cUn1gwtUoCM3/#cpp

#include <iostream>
#include <string>
#include <sstream>

using namespace std;

int main() {

string input = "";

int myNumber = 0;

while (true) {
cout << "Please enter a valid number: ";
getline(cin, input);

// This code converts from string to number safely.
stringstream myStream(input);
if (myStream >> myNumber)
break;
cout << "Invalid number, please try again" << endl;
}
cout << "You entered: " << myNumber << endl << endl;

return 0;
}

The program restrict non-integer values !
Try this !!
