Question

I have a programming assignment for a introductory c++ class and I am really struggling writing this program.

Below are the assignment requirements, I am unable to use vectors in stl and I keep getting a ton of compiling errors.

Thank you chegg experts. You have really helped me out this semester. Your responses and code has cleared up so many issues ive had.

Description

The purpose of this challenge is to employ the use of basic functions and arrays. This challenge will allow you to create a strong password as suggested by this xkcd.

********Do Not Use

********Vectors from the stl

Requirements

1. Create a function string create_password()
2. In the create_password() function:
   1. Create a string array called colors and initialize it to the following string values – be sure to indicate the first letters as uppercase for readability: Puce, Fuchsia, Sarcoline, Falu, Wenge, Sinopia
   2. Create a string array called animals and initialize it to the following string values – be sure to indicate the first letters as uppercase for readability: Zebu, Ibex, Kudu, Lynx, Fugu, Tarsier, Narwhal, Okapi
   3. Create a string array called numbers and initialize it to the following string values (they look like numbers, but make sure the values are set as strings): 31, 41, 59, 26, 53, 14, 867, 5309, 117
   4. Create a string array called symbols and initialize it to the following string values: !$, $$, ~!~, ^#^
3. In the create_password() function:
   1. You will use the rand() function to generate a random number that will be used as an index into each of the arrays. To use the rand() function to generate integers between 0 and 7, you might write something like animal_index = rand() % 8
   2. You will need to generate random integers to act as indexes into each of the arrays. Make sure that the indexes for each array don’t go out of bounds of the arrays to avoid segmentation faults.
   3. You will return a string that is a concatenation of a color, an animal, a number, and some symbols. A sample result of the function is PuceZebu41$$ – this would be the result of random integers being generated as array indexes as follows: 0 for the colors array, 0 for the animals array, 1 for the numbers array, 1 for the symbols array
4. In main():
   1. Create a string test_password
   2. Call the create_password() once to generate a random password and assign it to test_password
   3. Then, write a loop that will run 100,000 times calling the create_password() function within the loop. Examine the value returned by the function and compare it to test_password. If the values match, increment a counter.
   4. After the loop, report to the user the value of test_password and how many times the value stored in test_password was generated within the loop. Basically, we are testing how often the function will generate the same password.

Sample main()

You will need to at least have your code as indicated by the sample main() below. You should have the included header files and srand() function. Then, add the rest of the functionality as indicated by the descriptions above.

#include <iostream>

#include <ctime>

#include <cstdlib>

using namespace std;

int main()

{

srand(time(NULL));

string test_password;

int repetitions = 0;

// generate a test password

// loop 100000 and count repetitions

// report to user how many repetitions of test_password

return 0;

}

Sample Output

PuceZebu41$$ was generated 78 times out of 100000 repetitions

Answer 1

SOURCE CODE IN C++:

#include <iostream>

#include <ctime>

#include <cstdlib>

using namespace std;

//function to randomly create a password and return it

string create_password()

{

//declaring the array

string colors[]={"Puce", "Fuchsia", "Sarcoline", "Falu", "Wenge", "Sinopia"};

string animals[]={"Zebu", "Ibex", "Kudu", "Lynx", "Fugu", "Tarsier", "Narwhal", "Okapi"};

string numbers[]={"31", "41", "59", "26", "53", "14", "867", "5309", "117"};

string symbols[]={"!$", "$$", "~!~", "^#^"};

//randomly selecting an index in the arrays

int color_index=rand()%6, animal_index=rand()%8;

int number_index=rand()%9, symbol_index=rand()%4;

//using the index to form a string and returning it

return colors[color_index]+animals[animal_index]+numbers[number_index]+symbols[symbol_index];

}

int main()

{

//seeding the generator

srand(time(NULL));

string test_password;

int repetitions = 0; //to count number of repetitions of test password

test_password=create_password(); //generating test password

for(int i=0; i<100000; i++) //iterating 100000 times

{

string password=create_password(); //generating a password

if(password==test_password) //checking if it is test password

repetitions+=1; //incrementing count

}

//count

cout << test_password << " was generated " << repetitions << " out of 100000 repetitions.\n";

return 0;

}

OUTPUT:
