Hi, Just had a few questions about the assignment.

First, what should happen if divide by zero occurs, are we expected to do static analysis at compile time, throw an error at run time, or is it UB?

Second, in example 5 a function call is done using printsum 12 6, without any brackets or separators in the function call, whilst all other examples use function(args) as the syntax. Should we be able to parse both?

Also, with respect to command line arguments, should our program check if the number of arguments passed to the program is sufficient and print to stderr like follows

if (argcount < 2) {
        fprintf(stderr, "%s: program expected at least 1 argument",
                argvalue[0]);
        exit(EXIT_FAILURE);
    }

Thanks in advance.
