Question

how do I use do whiles

Answer 1

In C/C++, it would look like this:

1. while (condition) statement
2. do statement while (condition)

, where condition is any expression that can be evaluated to a boolean (true/false value) and statement is the instruction(s) that needs to be executed as long as the condition evaluates to true. Every time the statement is executed, the condition  is re-evaluated to check if it's still true.

For more details, please visit: https://en.cppreference.com/w/cpp/language/while

Other languages should have similar logic. You should be able to find online references for your language of interest.

You can consider the below "pseudo-code":

#include <stdio.h>

int main()
{
    int money = 100;
    while (money > GetIceCreamPrice())
        money -= GetIceCreamPrice();
    
    do
    {
        money += Work();
    } while (money < GetCarPrice());

    return 0;
}
