Question

pls help

2. Design a password generator that takes input from the user in the form of string and are integer. A string consists of four characters and a number consists of four integers obtained from the user. The following Figure 1 will explain how the password is generated. Print out the output for "asdf" and 1234. 14 12 13 C4 11 C2 C3 C1 Input 12 11 C1 13 4 C3 C2 C4 Re-arrange C2 C1 4 12 C3 13 1 Final password C4 Figure 1 (20 marks) m

Answer 1

//Program

#include<iostream>
using namespace std;

void swap(char arr[],int i,int j){
   char temp = arr[i];
   arr[i] = arr[j];
   arr[j] = temp;
}
void swapString(string& str,int i,int j){
   char temp = str[i];
   str[i] = str[j];
   str[j] = temp;
}

void Password(string str , int number){
   char num[4];
   int i=0;
   while(number){
       num[3-i] = number%10+'0';
       number/=10;
       i++;
   }
   swap(num,0,2);
   swap(num,1,3);
  
   swapString(str,0,3);
   swapString(str,1,2);
  
   string password="";
   password+=str[0];
   password+=str[1];
   for(int i=0;i<4;i++)password+=num[i];
   password+=str[2];
   password+=str[3];
  
   cout<<"password : "<<password;
}

int main(){
   string str;
   int number;
  
   cout<<"Enter string : ";
   cin>>str;
  
   cout<<"Enter 4-digit integer : ";
   cin>>number;
   Password(str,number);
   return 0;
}
