Can I pass a whole string as one command line argument into argv in C?

问题

Say I have a program like this:

int main(int argc, char **argv){
    printf("The name of the program is %s, and the string passed is:\n %s \n\n", argv[0], argv[1]);
    return 0;
}

I realize there should be error checking and whatnot, but what I'd really like to know is how to pass a whole string as the first argument or if it's even possible. Thanks!

回答1:

Just use quotes

./file_name "This is the long string argument that comes in argv[1]"
     |
     |
     +--- argv[0]

---

Edit:

aruisdante: single and double quotes are treated depending on the shell, double quotes might do unexpected things

^{PS: My answer comes from Windows platform, where use of single quote, simply skips everything after whitespace}
