Question

In C Programming, Thanks

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. You may assume that the string does not contain spaces and will always contain less than 50 characters.

• i becomes !
• a becomes @
• m becomes M
• B becomes 8
• o becomes .

Ex: If the input is:

mypassword

the output is:

Myp@ssw.rdq*s

CODE:

#include <stdio.h>
#include <string.h>
int main()
{
    char password[50]; //character array to store password
    
    printf("Enter your password: ");
    scanf("%s",password); //reading password from user
    
    char strongerPassword[52]; //array to store updated password
    
    int i=0;
    
    for(i=0;i<strlen(password);i++) //looping through the password
    {
        if(password[i]=='i') //if current character is i
        {
            strongerPassword[i]='!'; //storing replacement of that character
        }
        else if(password[i]=='a') //if current character is a
        {
            strongerPassword[i]='@';
        }
        else if(password[i]=='m')  //if current character is m
        {
            strongerPassword[i]='M';
        }
        else if(password[i]=='B')  //if current character is B
        {
            strongerPassword[i]='8';
        }
        else if(password[i]=='o')  //if current character is o
        {
            strongerPassword[i]='.';
        }
        else //other than any above character
        {
            strongerPassword[i]=password[i]; //storing same character in new password array
        }
        
    }
    
    //appending q*s at the end
    strongerPassword[i++]='q';
    strongerPassword[i++]='*';
    strongerPassword[i++]='s';
    
    printf("%s",strongerPassword); //printing new password
    

    return 0;
}
