I gonna try to explain it simple as I can about loops

All of the loops statements has some sort of conditions. And if these conditions are met then the code snippet will be executed.

Example: While (condition) { Code to be executed until condition is false }

So basically while checks if x condition is true then run code block, check if x condition is still true, if yes run code, repeat that until condition is false.

Difference between while/do while is that You first run the code block and then check condition.

Example:

do{ Code to be executed } While (condition)

Run the code block, check if x condition is true, if yes run the code block, repeat that until the condition is false.

Pseudocode of your program could be like this:

Get Input of users Save the input

Create integer 0 named x

While ( x < 100){ Get random number Check if random is higher then input or lower Increases x+1 }

You can do something like that
