C++ program for Validating password
#include <iostream>
#include<cstring>
using namespace std;
int main()//driver function
{
char password[100];//declaring variables password
int lower=0,upper=0,flag=1;
cout<<"Enter the password\n";//taking input
cin>>password;
int length = strlen(password);//finding length
for(int i=0;i<length;i++)
{
if(password[i]>=65&&password[i]<=90)/*checking string must contain at least one uppercase letter */
{
upper=1;
}
if(password[i]>=97&&password[i]<=122)/*Checking string must contain at least one uppercase letter*/
{
lower=1;
}
}
if(length<10)//checking that string length should be less than 10
{
flag=0;
cout<<"Password must be at least ten characters long\n";
}
if(upper==0)
{
flag=0;
cout<<"Password have to be at least one uppercase letter\n";
}
if(lower==0)
{
flag=0;
cout<<"Password have to be at least one lowercase letter\n";
}
if(flag==1)//if all condition turns out to true,printing Valid Password
