How to make input sentence into one string? or other method?

[ksm092]

Hey Guys! I am writing a program on C++ with linux that will require the user to use the program by typing:
./contactadd 12 June 2010 Jessica Daniels Description
It is a contact saver, I think I have the birthday (eg. 12 June 2010) saved and sorted, however I want the name and description to be converted to one string or something like that because I don't know how many words will make up the description.

This is what I have so far:

int main(int argc, char* argv[])
{
saveContact(string(argv[1]) +" "+ string(argv[2]) +" "+ string(argv[3]) +": "+ argv[4]);
}

as you can see the user can only input one word for the description and name.
How could I make it so the user can input as much words for the description as she/he wants?

Thanks!

argc is the size of the argv array, so you can get the date and such, then loop through the remaining arguments, appending them to a string.

Just implementing what Zhuge said:

#include <iostream>
#include <string>

int main (int argc, char** argv)
{
    std::string line = "";

    for (int i = 1; i < argc; i++)
    {
        line += argv [i];
    }

    // Just for testing
    std::cout << "Output: " << line << "\n";

    return 0;
}

You could require the user to quote the various fields

./contactadd "12 June 2010" "Jessica Daniels" "Description of some or other very young person"

or

./contactadd "21 June 1982" "William Arthur Philip Louis Windsor" "Second in the line of succession to the throne"

this will arrive as arg[1] - arg[3]

Or you could require some sort of delimiter between the fields.

./contactadd 12 June 2010 + Jessica Daniels + Description of some or other very young person + extra info (only first 2 pluses are special!)

(this choice of delimiter might cause problems for B.S.

./contactadd 30 December 1950 + Bjarne C++ Stroustrup  + C++ is his middle name!

)

You might also consider implementing a "beginner" mode, where you start the app with no command line params and it prompts for each field and then confirms before committing the data.
