i want to create a program that translates a sentance in english to another language

[DeMan]

Why can't you use the file as you did before?
What are the errors you were getting?

Using the text file would be a far better idea...

[jerger]

i guess i am lost. this one compiled so i was like sweet!

but the other one I hadn't compiled right. so i should try it again.

[DeMan]

Generally (in programs this small), so long as you can find the first error during compile, the problem is (reasonably) easy to trace.
When strange errors appear, it is most commonly mismatched parentheses or missing semi-colons.

deman i get these errors with your code

 
37 C:\hmong dictionary.cpp no matching function for call to `strncmp(std::string&, std::string&, <unknown type>)' 
  
note C:\temp\Dev-Cpp\include\string.h:51 candidates are: int strncmp(const char*, const char*, size_t)

[DeMan]

you can try substituting english.length( ) with english.size()
(in fact english is not declared in my original example, so you may like to add "string english" below "string line" if you haven't already.

Seeing as you have got an array version working, you may like to add the filehandling from the first with the array operations of the latter (then you don't need the strncmp), so that you read from a file into an array. Once you have the array, you can use the find method as you are.

i made your changes, similiar issue occurs. do we have to define the function at the bottom of the code? what would i do for that? this is what i got

errors:
37 C:\hmong dictionary.cpp no matching function for call to `strncmp(std::s tring&, std::string&, <unknown type>)'

note C:\temp\Dev-Cpp\include\str ing.h:51 candidates are: int strncmp(const char*, const char*, size_t)

code:


#include <iostream>

#include <fstream>

#include <string>

using namespace std;



int main () {

string line;
string english;


cout << "Type the english words here, then press enter. Make sure to copy the words correctly. If you need to spell check use www.google.com" ;

cin >> english;

ifstream myFile ("c:\\eAh.txt") ;

if (myFile.is_open ())

{

while (! myFile.eof() )

{

getline (myFile,line);

// int strncmp(line, english, english.length( ));

{
if (strncmp(line, english, english.size))
cout <<"Match found"<< line;

}

}

myFile.close();

}



else cout << "Unable to open file";


}

[jerger]

btw do you sleep? hahaha you are a great help

[DeMan]

This is generally considered bad practice, but you could try adding a cast to see if whether that's the problem:

strncmp(line, english, (size_t)(englis h.length()));
or
strncmp(line, english, (size_t)(englis h.size()));


[I'm in Australia so its almost 9 am here.....]

[jerger]

:(

that just causes more problems err. hehe

[DeMan]

I'll have a think about it.....
you can use
strcmp(String1, String2)
which doesn't need length (the one with length is considered safer because people find it harder to manipulate into overflowing/injecting format strings etc (because you limit the length), for a local app (and certainly for now), it may be worth trying it. )

12 C:\hmong dictionary.cpp expected constructor, destructor, or type conversion before '(' token

12 C:\hmong dictionary.cpp expected `,' or `;' before '(' token


if i actually put the ; in after this, it recreates both the new and old error messages! errr it makes no sense

[DeMan]

you could also use
[code=cpp]

int pos = line.find(engli sh);
if(pos!= string::npos)
{
//pos is the position of the begining of the word you are searching for in the
// string from the dictionary. If you have set up the file to have each line
// word, definition
// then pos must be 0 to be a valid word (otherwise you may get strange
// results - eg looking for "at" would leave pos= 1 in a string beginning "cat")
}
[/code]

[DeMan]

This error is at line 12 (which I suspect is where you declare the strings)

[jerger]

this just makes me more confused haha. it compiles, but just couts nothing and then closes

[jerger]

weird my .txt file i had

a little
awhile

it would not find awhile, it would just show up blank and do nothing.

i then put this in my .txt

fa
a little
awhile

and it worked! lol. i wonder why it hates two word, words....

also if you put...

fart
fa
a little
awhile

and search for fa, you get fart as your return
