Many user-created passwords are simple and easy to guess. write a program that takes a simple password and makes it stronger by replacing characters using the key below, and by appending "q*s" to the end of the input string.

i becomes !
a becomes @
m becomes m
b becomes 8
o becomes .

#include<iostream.h>

#include<conio.h>

void main()

{

char str[25],pass[25];

int i;

clrscr();

cout<<""\nEnter username"";

cin>>str;

cout<<""\nEnter password:"";

cin>>pass;

for(i=0;pass[i]!='\0';i++)

{

if(pass[i]=='i')

pass[i]='!';

if(pass[i]=='a')

pass[i]='@';

if(pass[i]=='m')

pass[i]='M';

if(pass[i]=='B')

pass[i]='8';

if(pass[i]=='o')

pass[i]='.';

if(pass[i+1]=='\0')

pass[i]='*';

}

cout<<""\nUsername: ""<<str<<endl;

cout<<""\nPassword now is: ""<<pass<<endl;

getch();

}

Explanation:

Here, the user is asked to enter his/her username and password. Since the user-generated passwords are easy to interpret and hack able, this program will accept the password and change it so to increase the password strength,(in other words, encrypting it). It uses a key such that whenever a letter is encountered, it is replaced by its subordinate in the key. Then the programs also appends at end of input string. It’ll  show the changed password to the user on the screen.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
