Thread: Search for .txt file

I want it to read the first line of text from the file and print it then move on the second line of text and print that etc.I was wondering if anyone knows whats the matter with this code as all it does is print:
"Name:
Value:
Weight:
Effect 1:
Effect 2:
Effect 3:
Effect 4:
"
But doesn't print anything where i want it to print the values from the file but this code doesn't work(lol)!

Well, as I see it, you have two options.
You can simply fix the code that way:

Code:

file2.getLine(info,100);
//where 100 is how much bytes are to be read and info is where to read 
cout<<"Name:" << info << endl;

and so on.
another way is making it a binary file (you'll need to save it binaricly first) like that:

Code:

#include <iostream>
#include <cstring>
#include <fstream>
using namespace std;
struct info{
//all of the members of the struct 
char name[100];
int value;
};
int main(){
ofstream out_file("binary.bin",ios::binary|ios::trunc);
info save;
strcpy(save.name,"NAME");
save.value=10;
out_file.write((const char *)&save,sizeof(info));
}

then, after you have saved the file, load it like that:

Code:

#include <iostream>
#include <cstring>
#include <fstream>
using namespace std;
struct info{
//all of the members of the struct 
char name[100];
int value;
};
int main(){
ifstream in_file("binary.bin",ios::binary);
info load;
//it'll be equal to 10;
load.value=18;
in_file.read((char *)&load,sizeof(info));
cout<<"Name:"<<load.name<< endl;
cout<<"Value:"<<load.value<< endl;

}

I guess that with some small changes you will also be able to output & input c++ strings(changing variables declarations from char to string,etc).
this code was compiled using borland c++ compiler and I dont know how will it work on other compilers. give it a shot and tell me what happend.

First of all, you should change the code below...

Code:

                                      getline(file2,info);
                                      cout<<"Name:" + info << endl;
                                      getline(file2,info2);
                                      cout<<"Value:" + info2 << endl;

to this...

Code:

                                      getline(file2,info);
                                      cout<< "Name: " << info << endl;
                                      getline(file2,info2);
                                      cout<< "Value: " << info2 << endl;

Notice the << operator after the "Name: " and "Value: "

And post what the .txt file looks like...

I agree

It is. I included it just to make sure the file was empty. the programmer should declare "info save"(info=type & save=name).
lastly, if you havent compiled and run the first code, the second wont work. BTW did anything worked on your compiler(including the getline)?

Thanx for the help i changed that but it still doesn't print anything!Also a note to gftmc it does nothing whatsoever i ran it and edited the .bin file entered some values and it prints still nothing however it DOES compile which is some good news as thats half the struggle(lol)!

post an update of your code... so we can get another idea...

OK here we go:

Code:

                                      for (i = 0; i < 25; i++)
                                      putchar ('\n');
                                      cout<<"Please entre the name of the ingrediant:";
                                      getline(cin,filename);
                                      std::ifstream file2(("Ingrediants\\" + filename + ".txt").c_str());
                                      getline(file2,info);
                                      cout<<"Name:" << info << endl;
                                      getline(file2,info2);
                                      cout<<"Value:" << info2 << endl;
                                      getline(file2,info3);
                                      cout<<"Weight:" << info3 << endl;
                                      getline(file2,info4);
                                      cout<<"Effect 1:" << info4 << endl;
                                      getline(file2,info5);
                                      cout<<"Effect 2:" << info5 << endl;
                                      getline(file2,info6);
                                      cout<<"Effect 3:" << info6 << endl;
                                      getline(file2,info7);
                                      cout<<"Effect 4:" << info7 << endl;
                                      file2.close();
                                      cin.get();
                                      break;
