I had presumed it was almost identical to rand just "safer". To use rand_s just don't forget to #define _CRT_RAND_S before stdlib.h is included.

The seed is then changed in every generating `rand()`. In your code, you issue randomizer `srand(T)` reset the seed to the system time in every run. But the system time didn't changed, Thus, you are reseting the `seed` to a same number. Run this test. decker medicaid expasionWebGitiles.

The reason is important: as global state, the seed must be set once (consider that, if multiple headers each set the seed with time (0) before drawing their “random” numbers, they would typically all get the same results). febblue how to et member id
