File I/O

[xXmusicmanXx]

So I was able to do part of a program, and only got stuck on one part. The program uses text input file to return things such as age and gender. However, The only thing that I couldn't get any output for was string name. For example, the input file had Joe Bob and the compiler returned your name is, but not Joe Bob. This is a hw questions so please hints only. I included <string> and all that other stuff. Like my book says, "it should read a string value from one line of an input file."

This is what I have:

string name;
cout << " Your name is " << name << endl;
getline(fin, name);

Again hints only and thanks in advance!

note: I am using win 7 notepad as an editor, VC++ 2010 express as a compiler, and am using a PC.

It is not clear your hw for me. I guess you have a file that contains some info:

Little Joe
28
male
Joe Bob
35
male
etc.

Moreover you need to get a name and you have to search this name in the file and print the other things besides name, doesn't it?

First you should read the name, secondly you should use the getline on every line in the file because of searching the particular name. You can do it in a loop. If you find it, you can read more data.

Some help:

read a string as a name
http://www.cplusplus.com/reference/iostream/istream/operator%3E%3E/


read a line from a file
http://www.cplusplus.com/reference/string/getline/

You can compare both string with assignment operator.

it looks like you are outputting the variable name BEFORE you put a value in it when you use the getline(cin, name);
