C/C++ Programming under Linux - Part 2

Most console programs in GNU Linux ( for that matter Windows ) accept command line arguments. The following program will spit the arguments given at the command line to the console.

///////////////////////////////////////////
// commandline.cpp
//
// Command Line argument spitter
//
// g++ -ocmdline.exe commandline.cpp
//
//
#include <stdio.h>


int main( int argc , char **argv )
{
  if ( argc == 1 ) {
    printf("No command Line Argument\n");
    //
    // argc will be at least 1 in the case of C/C++ Programs
    // argv[0] will contain the executable name
    return 0;
  }


  //---------------- Print the Executable name
  printf("%s\n", argv[0] );
  

  //------------- Spit the rest of the arguments
  for( int j=1; j< argc ; ++j )
    puts(argv[j]);

}
