Help creating a Text Editor in C

[Nineshadow]

@Nineshadow Just a friendly reminder in case you forgot.

 

//if you're busy/lazy then feel free to ignore this

I've been busy today. Just now I've got home to use my computer.

 

I'm trying to implement my own version out of curiosity. Let's see how it turns out.

I'm not too familiar with C (haven't used it too much) , but I made it your text editor in C++ :

#include <iostream>#include <fstream>#include <string>#include <vector>using namespace std;fstream file;vector<string> v(0);void help(){    cout<<"This is a text editor written in C++.\nYou can open it with the command : editor.exe <file_to_open>./nUsage : \np - Print everything in the file.\np <line_nr> - Print everything in the file found at line nr <line_nr>.\nw <line_nr> <string_to_write> - write <string_to_write> at line nr <line_nr>.\n";}void print(){    for(vector<string>::iterator it = v.begin(); it!=v.end(); it++)cout << *it << '\n';}void printl(int line){    if(line < v.size())        cout << v[line]<<'\n';    else cout << "Line not found.\n";}int main(int argc, char *argv[]){    switch(argc)    {    case 1 :        help();        break;    case 2:    {        file.open(argv[1], ios::in | ios::out);        string str;        while(getline(file,str))v.push_back(str);        str.clear();        file.close();        bool running = 1;        while(running)        {            getline(cin,str);            if(str[0]=='p' && str.length() < 2) print();            else if(str[0]=='p')            {                int line = (int)str[2]-48;                printl(line);            }            else if(str[0]=='w' && str.length() > 4)            {                int line = (int)str[2]-48;                string s = str.substr(4);                v[line] = s;            }            else if(str[0]=='s')            {                ofstream out(argv[1]);                for(vector<string>::iterator it = v.begin(); it!=v.end(); it++)out << *it << '\n';                out.close();            }            else if(str[0]=='q')            {                running = 0;                return 0;            }            else help();        }    }    break;    default :        return 0;    }}

Now, time to see what's wrong with your implementation.

God I hate vectors... never really understood that shit.

Vectors are basically resizable arrays.

yea....I know, but I've never been great with vectors. 

/I miss java arrays

Pointers ftw.

@Nineshadow So I wasn't able to figure it out, but I'm still curious to know why it wasn't working (even though I'm already passed the deadline, and have another code due tonight that I'm also having some trouble with :unsure: )

Ah, sorry. School has just started today and I forgot about your problem.

On another note, does the implementation I made in C++ work the way it's supposed to?

[Nineshadow]

Ok, got it up and running (getting no more compiler errors).

Commands don't really work for me.

Printing crashes my program.

Saving doesn't do anything.

Yep, that's where I'm stuck at  

 

And I didn't get a chance to try your c++ version out as I've been swamped with work (but still doing a good job of keeping myself distracted :unsure:)
