A website requires that passwords only contain numbers. For each character in passPhrase that is not a number, replace the character with $\text{'}0\text{'}($the number zero$).$

Ex: If the input is $2>43,$ then the output is:

Valid password: $2043$

Note: isdigit$()$ returns true if a character is a digit, and false otherwise. Ex: isdigit$(\text{'}8\text{'})$ returns true. isdigit$(\text{'}$a$\text{'})$ returns false #include

#include

using namespace std;

int main$()\{$

string passPhrase;

unsigned int i;

getline$($cin$,$ passPhrase$)$;

$/*$ Your code goes here $*/$

cout $<<$ "Valid password: $"<<$ passPhrase $<<$ endl;

return $0$;
