Thread: Comparing a text file with a dictionary file help!!

Hi, i'm trying to compare two text files..one is a user created file and it needs to be compared with a dictionary file. It is then supposed to output which word if any is spelled wrong and display which line number. Can someone guide me in what to do, and maybe supply me some code? thanks!

Code:

#include <iostream>
#include <fstream>
#include <cstdlib>
using namespace std;

bool word_search(string, string);
bool bad_word(string, int, ostream&);



int main(){
	ifstream ins;
	ofstream outs;
		string outFile;
		string inFile;
		string line;
		int lineCount;
		lineCount = 0;
	
		cout << "Please enter an output filename: ";
		cin >> outFile;
		
		cout << "Please enter an input dictionary file: ";	
		cin >> inFile;
		
			
			
				
				
	word_search(outFile, inFile);
			
	return 0;
}
bool word_search(string out, string in){
	ifstream ins;
	ifstream ins2;
	ofstream outs;
	ofstream outs2;
	string line;
	int lineCount;
	lineCount = 0;
	

	
			ins.open(in.c_str());
				if(ins.fail()){
					cout << "***Error: Cannot open " << in
						<< 	" for input." << endl;
					return EXIT_FAILURE;
				}
				
			ins2.open(out.c_str());	
				if(ins2.fail()){
					cout << "***Error: Cannot open " << out
						<<  " for output." << endl;
					return EXIT_FAILURE;
				}	
				
				
		
			getline(ins, line);
			while(!ins.eof()){
				lineCount++;
				cout << line << endl;
				outs << line << endl;
				getline(ins, line);
			}
			
			
		
	
			getline(ins2, line);
			while(!ins2.eof()){
				lineCount++;
				cout << line << endl;
				outs2 << line << endl;
				getline(ins2, line);
			}
			
		
				
			
			return 0;
		
	
		
	}

well with the code i have right now, it displays me the words in both files, but I don't know how to actually compare the strings in both files to each other so as to check and see if a word is spelled correctly

stl::set might be of some use. Depending on the format of your dictionary then

Code:

std::set<std::string> dict;
std::ifstream dict_stream(dict_filename.c_str());
for(std::string word;dict_stream >>word;) dict.insert(word);

might be all you need to do to parse your dictionary. if dict.count(word) == 0. then the word never appeared in the dictionary.
std::getline(std::istream,std::string,char); will get a line from a file
now all you need is to write a function to split a string into two strings, one containing the first word without any whitespace and another containing the rest of the string. a function to convert a string to all lower case might not be a bad idea either.
