@TechandMystery
You described how to do all this in 20 minutes, what my school book took a million pages to describe. (Give or take a few hundred thousand pages.) Thank you!
@klevismema4998
Hey I commented in your last video and I said I was going to have a exam in c++ . I managed to get a 10/10 max score, thank you very much for helping me personally it was such a great journey through these series.
@meekosalas1153
Prefect timing, we are dealing with File I/O this week in class
@d3v1ce
hiya, im only 4 years late here but thank you so much for saving lives one day before my exam
@sehrishzarin2431
my course constructors ignored this chapter even in exams last semester , now that i want to make my own project i realized how important this topic is
@luxis_2295
I’ve been having the doubt of how read and write from a file for weeks because my programming professor did not explained as good as you. You were the light that lit the way for me because I needed it for a project. Thank you Saldina!!
@potatoitis3326
Saldina thank you for making this concept easier to understand. You are definitely an inspiration and I hope to be as great at programming just like you someday.
@con_el_maestro3544
I cannot believe that I finally understand this, I'm gonna cry😭. Anyway let me get started with the homework you gave us
@priyanshusaxena7157
My solution for the 1st challenge, converting a story to cipher and deciphering back the code in the console:
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main()
{
fstream Myfile;
// Taking the input string from the user
string story;
cout << "Enter a story: \n";
getline(cin, story);
// Converting the string to character array
char story_char[story.length()];
for (int i = 0; i < story.length(); i++)
{
story_char[i] = story[i];
}
// Ciphering the story and writing it into the file.....
Myfile.open("story.txt", ios::out);
if (Myfile.is_open())
{
for (int i = 0; i < story.length(); i++)
{
Myfile << int(story_char[i]);
}
}
Myfile.close();
// De-ciphering the numbers into story.....
cout << "The deciphered numbers form the story:\n ";
Myfile.open("story.txt", ios::in);
if (Myfile.is_open())
{
string line;
while(getline(Myfile, line)){
int num = 0;
for(int i = 0; i < line.length(); i++){
num = num * 10 + (line[i] - '0');
if(num>=32 && num<=122){
char ch = (char)num;
cout << ch;
num = 0;
}
}
}
}
Myfile.close();
return 0;
}
Input:
Hello, my name is Priyanshu Saxena, and I am from India, and I love watching videos on CodeBeauty channel.
Ciphered Text: 72101108108111443210912132110971091013210511532801141051219711011510411732839712010111097443297110100327332971093210211411110932731101001059744329711010032733210811111810132119971169910410511010332118105100101111115321111103267111100101661019711711612132991049711011010110846
Deciphered in the console:
Hello, my name is Priyanshu Saxena, and I am from India, and I love watching videos on CodeBeauty channel.
@Seanxiao-p3r
I recently started to work on a project which is in C++. I literally knows nothing about C++ and came to you channel. You literally saved my work... Please continue doing this! Many thanks!
@omarbenamer9985
IT HAS BEEN DAYS OF HARDWORK THAT I PASSED THROUGH IN ORDER TO GET MY FIRST APPLICATION, WHICH IS CONCERNED TO BE THE END OF THE YEAR FINAL PROJECT BY YOUR ENLIGHTENMENT; YOU MAKE ME SO HAPPY BECAUSE I COULD SOLVE MANY PROBLEMS THAT I FACED WITH FILES
@bigbro_songz
Big Bro 3 minutes ago I just love how you make coding so simple, Saldina. You have a great gift. Keep up the good work👏🏽👏🏽👏🏽
@sinnyx3248
explained my 3 lectures from college in 15 mins!! this is so sick because Ive actually understood you better
@fishtailsL0
New video from codeBeauty notification, me on the road running as fast as I can to watch it. Thanks Saldina.
@tabathaelrod1504
Thanks!
@Lancelot251
The answer to the ques 1 is this :
#include<iostream>
#include<fstream>
#include<string>
using namespace std;
int main()
{
fstream file;
//user input
string cont;
cout<<"Enter the story :\n";
getline(cin,cont);
//writing the content to be encoded
file.open("enconding.txt",ios::out);//write
if(file.is_open())
{
for(int i=0;i<cont.length();i++)
{
file<<int(cont[i]);
}
}
file.close();
//processing the out put to the console in the decrypted form
cout<<" \n\nThe decoded text is : \n\n";
file.open("enconding.txt",ios::in);//read
if(file.is_open())
{
string line;
while(getline(file,line))
{
int a=0;
for(int i=0;i<line.length();i++)
{
a=a*10+(line[i]-'0');
if(a>=32 && a<=122)
{
char ch = char (a);
cout<<ch;
a=0;
}
}
}
}
file.close();
return 0;
}
Input : this is nice.
clipped text in the file is : 116104105115321051153211010599101
@asishcodes
I have an exam on Object oriented programming in less than 2 hours and these videos are a life saver :- )))
@satyaprakash2910
I am a beginner starting from yesterday. Your videos are so easy to understand. I am going to watch all videos of your channel. i started from your beginner's playlist
@nidadursunoglu6663
normally these videos stress me out but your tone is so calming
