Exactly

  #!/usr/bin/tcc -run
  
  #include <stdio.h>
  
  int main(int argc, char **argv)
  {
      printf("Hello from C!\n");
  
      for (int i = 1; i < argc; ++i)
          printf("argument %d: %s\n", i, argv[i]);
  
      return 0;
  }

And ready is your cscript :)

  $ chmod u+x cscript && ./cscript hello world
  Hello from C!
  argument 1: hello
  argument 2: world

(I can't even articulate why I love it so much that this works)
