4 digit lottery random generator

[cblack618]

Hello,

I'm trying to create a random four digit lottery number generator that outputs five different 4 digit lottery numbers between 0000 and 9999.

Thank you

How far have you got?

One could:

But trivial way to ensure unique results is with:

For printing with 0-prefix:

Learn how to generate random numbers. Using the <stdlib.h> and <time.h> libraries if writing a C program, using <random> and <chrono> if creating a C++ program.

Write some code.

Simply (figuratively) throwing up your hands and saying you can't do it is not a good way to start.

Understanding a bit of theory on how to generate pseudo-random numbers in tutorial form might be helpful to get things going:
