i have understood little bit that public means for whole method.
static?
void?

Can anyone help me to code this
Write a method 'timesTable()' which accepts an integer value num from the keyboard and uses it to print 'times table' of itself in a structured format. Your output must include a header row. For example, if the user enters 5, your program's output should be:
5 Times Table
1 5 5
2 5 10
3 5 15
4 5 20
5 5 25
6 5 30

so although using srand(time(0)) can be used to get truly random numbers, how truly random are they? For example, if one were to call this method at the same time (in this example, if one were to use this command at 51s) each time would the numbers generated be the same???
If so, are the numbers still truly random??
And if this theory is true, how can one generate truly random numbers that cannot repeat based on external variables (e.g., time)?
