time Delays and Random functions
How do i write Time delay functions or instructions?
Like Delay for 40us or 80ms? But how do i make them "overlap" if i had multiple time delays going on? How do u modify or manipulate the random function? Where can i get external random function librarys or librarys that have different random functions? Each programming language has different random functions that are different ways of getting a random generator how do i call different programming language librarys please? |

How do i set the "random seed" To get different random number sequences?
What sets the random number sequences like how to i change the "order" of the "number sequence"? How do u change the current time at program's startup? Why is the sequence is different at each startup? How do u change the returns a random value in range? |

Make a call to srand.
What order? Look at <ctime> functions and make an OS API call. What sequence? Change what?

#include <ctime>
int Rand(int num);
int Rand(int num)
{
unsigned int _time = time(NULL);
srand(_time);
return (int) rand() % num;
} |

How to change the sequence order?
How to change the random order? Why make a OS API call? How do i call external librarys that have random functions please? How do i call external programming languages functions that have different random functions please? |

What is the theory behind random generators?
How can i make a random generator by scratch and manually make one from ground up please? The Random function is controlled by a Timing clock? |

Where can u get different seeds?
or can u make up seeds from scratch? The seed generates the psudeo random number? Which clocks? What is a "pid" please? ""something non-constant is probably best so that its not something you can guess and get the exact same results every time."" Can u please give examples |
