Long answer to follow. . .

The C standard defines main something like:

Code:

---

int main(int argc, char *argv[])

---

The command shell forms up the command and all parameters into an array. Each space creates a new parameter. So, for the example above your argv would be:

argv[0] = "program.exe"
argv[1] = "mycode.c"
argv[2] = "output.txt"

and argc would be 3.
