* Print a list of 256 random RGB colors,
* except some colors at front of list are predetermined.
* Also prints the seed used (epoch time in seconds).
* R component is first.
* Colors are at least a certain distance apart.
* May fail to find a color that is not too close
* to previously generated colors, then the program prints and exits.

Costava / sscanf_overflow.c
Created April 29, 2021 04:17
The return value of and the value read by sscanf are misleading/wrong when an integer greater than INT_MAX is read.
//
// File: sscanf_overflow.c
// Author: Costava
//
// If sscanf is given a string of an integer greater than INT_MAX,
// sscanf will still return 1 even though the integer cannot have been
// read correctly into the given variable.
//
// errno gets set to ERANGE
// errno can be checked to see if sscanf actually succeeded.
