Question

Write a C++ program that prints out all of the command line arguments passed to the program.

Each command line argument should be separated from the others with a comma and a space.

If a command line argument ends in a comma, then another comma should NOT be added

Answer 1

C++ Program:

/* C++ program that prints out all of the command line arguments passed to the program */

#include <iostream>
#include <string>

using namespace std;

//Main function
int main(int argc, char* argv[])
{
    int i, len;

    //Printing total number of command line arguments
    cout << "\n\n Total number of Command line arguments : " << argc << "\n\n";

    cout << "\n Command line arguments: \n\n";

    //Iterating over command line arguments
    for(i=1;i<argc;i++)
    {
        //Getting length of current argument
        len = strlen(argv[i]);

        //If last character is a comma
        if(argv[i][len-1] == ',')
        {
            //Just print the argument along with space
            cout << argv[i] << " ";
        }
        else
        {
            //Just print the argument along with comma and space
            cout << argv[i] << ", ";
        }
    }

    cout << "\n\n";

    return 0;
}
