If the height value is less than 2 or greater than 32, then print an error message "Error: height must be between 2 and 32." to standard error, and return EXIT_FAILURE, which is a macro defined in stdlib.h.

#include #include

void square(int height) { }

int main(int argc, char **argv) { if (argc != 2) { fprintf(stderr, "Error: program must be run as: `./square n` "); return EXIT_FAILURE; } int height = atoi(argv[1]);

// TODO: verify height is in the valid range.

square(height); return EXIT_SUCCESS; }
