Comp 110 random(_)

The 'random(_)' Function

Like all of our introcs functions, random needs to be imported!

import { random } from "introcs"; 

This is what the function definition looks like:

let random = (floor: number, ceiling: number): number => {

     //...

}

random takes in two number arguments that act as the 'floor' and the 'ceiling'.

The number that is returned by the function will return a randomly generated number between the floor and the ceiling. So, calling:

print(random(1, 10));

will print a random number between 1 and 10.

The floor and the ceiling are inclusive, meaning the generated number will be >= floor and <= ceiling.

Example of use:

​let whereShouldIStudy = () : string => {
     let randomNumber = random(1,4);
     if(randomNumber === 1) {
          return "Old Well";
     } else if(randomNumber === 2) {
          return "Bell Tower";
     } else if(randomNumber === 3) {
          return "Dean Dome";
     } else {
          return "Franklin Street";
     }
}
//whatever number is generated will determine what string is printed!
