How can I pass a command line argument which contains space character to my C++ program?

We can access command line arguments via argv code in C++, I know that.

But the problem is, if an argument contains space, then my program works like as if there are two parameters.

For example if the argument is foo bar, my program sees two parameters (foo and bar).

Here is my code:

string strParameter = string(argv[1]);

So, what should I do?

Ok, I have fixed my problem myself.

Here is my solution:

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

This is determined by your shell, not your program. In most shells, you can solve this either by wrapping the parameter in single and/or double quotes:

  • "foo bar"
  • 'foo bar'

or putting a special symbol before the space:

  • foo\ bar
  • foo^ bar in CMD (on Windows)
