password character length
Jan 25, 2018 at 8:23am UTC
Can someone show me how to write a programme that knows how many letters your password is, I'm trying to create a password page in which you're password must be at least 6 characters long with 1 number.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43
#include <iostream>
#include <algorithm>
#include <cctype>
#include <string>
using namespace std;
int main()
{
string password = "ba55555as" ;
if (password.length() < 6)
{
cout << "short" ;
// password too short
}
else
{
// password is long enough
cout << "long" ;
// use of a std algorithm and lambda function.
if (std::find_if (password.begin(),
password.end(),
[](char s)
{
return (0 != std::isdigit(s));
}) != password.end())
{
// it contains at least one digit
cout << "digit" ;
}
else
{
// doesn't contain any digits
cout << "no digit" ;
}
}
}
