Command Line Arguments

Command-line arguments are accessible through two parameters in main():

• int argc: Argument count.
  • Includes the name of the executable itself.
• int * argv: Argument values stored as strings in a 2D array.
  • Rows are fixed to value of argc.
  • Columns are strings that save the various command line arguments.
  • Explicit allocation not needed.

Example: Printing command arguments

#include <stdio.h>
int main(int argc, char **argv) {
  for (int i = 0; i < argc; ++i) {
      printf("%s\n", argv[i]);
  }
  return 0;
}

Example Interaction:

```bash
$ ./a.out -x -c -v -b
./a.out
-x
-c
-v
-b
