Random Numbers

Programming languages typically have a way of generating a random number. Some are simpler than others.

In reality, computers can only create "pseudorandom" numbers because they are created from a mathematical procedure or algorithm. Almost every programming language has the ability to generate some sort of random value - it might be up to the programmer to convert that value to an integer or specific type of value.

Javascript uses to generate random numbers.

let

C++ is a strongly typed language... content coming

// Content coming...
int

Java also uses a math library... content to come

Python always has to be a bit different...
