Got confused so I'll start from scratch

[RonKevin]

PART 1 of my Project:Using turbo c++ 4.5, and I'm very new to Programming, i'm not good
1. I made a program which stores 100 records please check if it's right.
2. I want to read each line into an array. I want to use a struct or what they call a struct array but i'm not yet familiar with it so I'm confused...I can't seem to figure out how would I read this .txt file and then store the data on the struct array.
I would like to read the txt file at the very first line of void main()

-the text file is long so I was thinking of reading it by using for loop/s...I tried and tried but failed miserably...

The above code is okay, given you are compelled to use Turbo. ;)

So, whats your question ? And, why aren't you using class instead of struct ?

[RonKevin]

we havent tackled it yet...if you want, you can teach me now..hehe.btw, we are making a Point of sale system, so are you saying its much more easier to do my project using classes??can you teach me?hahah..right now, im serious.WHAT is my question?well, Im trying to read the txt file but since its long as hell I figured to use a for loop/s to read it but I failed to do it...If you can help me with that, it would be awesome...thats really the problem I have now....If it works then I think I just need to make another struct, but how do I store the read data onto that struct..

[np complete]

Yes you need a loop for reading data from a file. Like this

// using File pointer

File *fp ; 
char c;

fp = fopen( "data.txt", "r") // means open file data.txt in "r"ead mode



while ( ( c = getc( fp ) ) != EOF )

          //means read a character at a time from a file unless EOF is encountered
{
   putc(c, stdout);
}

//same program using stream

fstream fp ( "data.txt", ios::in | ios::out);

char c ;

while( ! fp.eof() )
{
  c = fp.get();

  cout<< c;
}

[RonKevin]

wtf was that?!hahaha..damn...will that work on my compiler?I'll try

[np complete]

If you use class, reading and writing becomes simplified.
It uses read and write functions, for example :

// suppose you have a class student with their member data and member functions

student boy1;

fstream fp("data.dat" ios::in | ios::out)

while( ! fp.eof()) //reading from file
{
   fp.read( (char *) boy1, sizeof(boy1));
}

// writing to file

student boy2 ;

// take info of boy2

fp.write( (char *) boy2, sizeof(boy2));

You were told here about void main(), conio.h

You were told here about conio.h, void main(), putting non-code into your code to confuse us.

You were told here and here about void main()

And here about using goto

here again void main() was mentioned.

And I know goto, conio.h, formatting your code, and not proofreading your post has been mentioned before.

Question -- if you refuse to listen, why should we help you?
