Hi guys,
When I try to compile the code below I get an error saying: error C2065: 'file' : undeclared identifier. But if I run the program it still works.
// WordStreamTest.cpp
//--------------------------------------------------------------------
#include "WordStream.h"
//--------------------------------------------------------------------
using namespace std;
//--------------------------------------------------------------------
void OutputNumber (const string &str);
void OutputLine (int length);
void testNext (WordStream &file);
//--------------------------------------------------------------------
int main()
{
string filename;
cout << "Enter file name: ";
cin >> filename;
//error here
try
{
WordStream file(filename);
}
catch(...)
{
cout << "File cannot be opened!" << endl;
exit(1);
}
testNext(file);
return 0;
}
//--------------------------------------------------------------------
void testNext (WordStream &file)
{
string word;
OutputNumber("Getting word from file stream");
cout << "Expected Output: this is a test to see if this number 1 test works\n";
cout << "Actual Output: ";
while (file.Next(word))
cout << word << " ";
cout << "\nIF Expected Ouput matches Actual Output:\n"
<< "THEN Test Passed\n";
system("pause");
}
//--------------------------------------------------------------------
void OutputNumber (const string &str)
{
static int num = 0;
num++;
cout << "\n";
OutputLine ((int)str.length() + 17);
cout << " TEST NUMBER " << num << ": " << str << "\n";
OutputLine ((int)str.length() + 17);
}
//--------------------------------------------------------------------
void OutputLine (int length)
{
for (int index = 0; index < length; index++)
{
cout << "-";
}
cout << "\n";
}

//Closes the file stream if one is open

//Fetches the next word from the input file

WordStream &operator = (WordStream const &stream) {};
};
#endifIf anyone can point me in the right direction to what I need to do it would be greatly appreciated.
