Set hasDigit to true if the 3-character passCode contains a digit.

HELP ME FIX THIS

#include <iostream>
#include <string>
#include <cctype>
using namespace std;

int main() {
bool hasDigit;
string passCode;

hasDigit = false;
cin >> passCode;

for(int i=0;i<passCode.length();i++) {
if(isdigit(passCode[i])) {
hasDigit=true;
break;
}
}

if (hasDigit) {
cout << "Has a digit." << endl;

#include <iostream>
#include <cctype>
#include <string>
using namespace std;
int main()
{
   bool hasDigit;
   string passCode;

   hasDigit=false;
   cin>>passCode;
   
   hasDigit = isdigit(passCode.at(0)) || isdigit(passCode.at(1)) || isdigit(passCode.at(2));

   if(hasDigit) {
      cout<<"Has a digit"<<endl;
   }
   else {
      cout<<"Has no digit"<<endl;
   }
   return 0;
