    Question

    I have a program and one of the things i need to do is search through the list of movies and find all the ones that have a certain word in it. Any ideas on how i could do this? Thank you.

    There might be something in there.

    OP, when you say "list of movies", what do you mean? a file with a bunch of names? a directory of mpegs?

    post more info on the problem and tell us what you've tried so far.

    If you program in C++, you need Boost. You should also know how to use the Standard Library (STL). Want to make games? After reading this, I don't like WxWidgets anymore. Want to add some scripting to your App?

    The list of movies is in a .txt file. For example :

    Meet Joe Black
    Meet the Parents
    Someting about Mary
    Gone in 60 seconds
    Father of the Bride

    fstream in(" \\insertfile name here.
    string s;
    while(getline(in,s,'\n')){
    if(s.find("seconds")!=string::npos)
    cout<<s;
    }
    Code:
     
    but remember one thing Joe is not the same as joe.

    well, here's one way you can do it... note that it's inefficient:
    Code:
    #include <iostream>
    #include <fstream>
    #include <string>
    
    std::string capitalize(std::string&in);
    
    int main()
    {
    	std::string word;
    	std::string search;
    	int line=1;
    	char ch;
    
    	struct link;
    	struct link
    	{
    		int data;
    		link*next;
    	} *curr,*next,*head=new link;
    
    	curr=head;
    	curr->data=-1;
    	curr->next=0;
    	
    	std::fstream file("test.dat",std::ios::in);
    	
    	std::cout<<"Enter your seach word: ";
    	getline(std::cin,search,'\n');
    
    	while(file>>word)
    	{
    		file.get(ch);
    		if(capitalize(search)==capitalize(word))
    		{
    			curr->data=line;
    			next=new link;
    			curr->next=next;
    			curr=next;
    			curr->data=-1;
    			curr->next=0;
    		}
    		line=(ch=='\n'?line+1:line);
    	}
    
    	curr=head;
    	std::cout<<"Matches were found on line(s): ";
    
    	while(curr->next)
    	{
    		std::cout<<curr->data<<", ";
    		curr=curr->next;
    	}
    
    	std::cout<<std::endl;	
    	return 0;
    }
    
    std::string capitalize(std::string&in)
    {
    	for(unsigned int i=0;i<in.length();i++)
    	{
    		in.at(i)=toupper(in.at(i));
    	}
    	return in;
    }
    and don't even try to take this as your own work... you would most certainly fail the assignment if you handed this in

    you'd best ignore the curr/head/data/link stuff and figure out your own way to record the results - I just put that in there to ensure you didn't get copyable code... sure, it works, but it's only half a program... (don't take that wrong, the searching algo is complete, it's the linked list that's not finished.)

    searching algorithms can get fairly complex, as touched upon in this wiki article, but on small amounts of data like this, you probably aren't looking for a very good algorithm.
