Question
I have a word file named words.1 and am trying to run it in the command line of c++ on visual studio. I do not understand where to save the word file to and what to put on command line to access it. I feel like I've tryed everything. Anyone know the answer to my problem?
#include <iostream>
#include <ctype.h>
#include <string>
#include <fstream>
using namespace std;
struct CmdLineRecord
{
enum { MAX_NAME_LENGTH = 32 }; // Max allowable filename chars
int SyntaxError; // True if user syntax is incorrect
int WantsLineCount; // set to true if user wants line count
int WantsWordCount; // set to true if user wants word count
int WantsCharCount; // set to true if user wants char count
};
struct CountsRecord
{
unsigned LineCount; // number of lines
unsigned WordCount; // number of words
unsigned CharCount; // number of characters
};
void DetermineWhatUserWants(CmdLineRecord & User, int arg, char * arv[]);
int CountLineWordChar(CountsRecord & Data, char File[]);
void ReportResults(CmdLineRecord User, const CountsRecord & Data);
int main(int argc, char * argv[])
{
CmdLineRecord User;
CountsRecord Data;
int FileOpened = 1;
DetermineWhatUserWants(User, argc, argv);
if (!User.SyntaxError)
FileOpened = CountLineWordChar(Data, argv[1]);
if (FileOpened)
ReportResults(User, Data);
else
cerr << "Cannot open file " << argv[1];
return 0;
}
/************** DetermineWhatUserWants ****************************
Action : Function will determine what the user wants to have displayed
for the count, based on command line input, i.e. does user
want to display how many lines or words or characters or
combination of them, or if an input error occurred. Second
argument in command line must be the file name the third argument
is the option of display.
Command line options are inputed after the "/" char and are:
c : character count
w : word count
l : line count
If no options are inputed then the default of display all count
totals is done, otherwise the option is done. One option or two
is permitted after the "/", illegal character option will result
in a syntax error.
Parameters:
Reference :
U : User variable of struct type given above
Value
arg : number of command line arguments
*arv[] : array of pointers each pointing to different argument
Returns : nothing
Preconditions : None

Words are delimited by whitespace characters and EOF.
Does not take into consideration hypentation, words are composed

Explanation / Answer
Hi,
I checked your program it is correct no error found.You can use Command line arguments to access your code.
Command line arguments are optional string arguments that a user can give to a program upon execution. These arguments are passed by the operating system to the program, and the program can use them as input.On the command line, to run a program, you can simply type in its name.
Then go to its installation directory.Inside that command line window, browse to where your source code (CPP file) is at. You do so by using the cd command.
C: directory name >Words.txt
I hpe information is useful for you
