This is pretty sad. Emil hit submit sooner than I did The "accepted" should go to him You have less rep, and it's an extremely simple question, so I'll gladly give it to you.
As jalf said, though: If you want an do until loop rather than a do while loop you'll have to negate the condition. Thanks a ton for your help, you guys! SO is the best! Only if null is an instance of type Planet. Show 5 more comments. When you want to check the condition at the beginning of the loop, simply negate the condition on a standard while loop: while! Zifre Zifre You could use macros to simulate the repeat-until syntax. Christian 6 6 silver badges 22 22 bronze badges.
This is exactly what I was looking for. Not sure how the "exp" works though. Is it a generic wildcard? Thank you! C It's an argument name. The second define makes a macro, which acts sort of like a function. So, in this case, define until exp is a macro named until which takes a parameter exp , and expands to while!
Thank you Conor. OK as for toupper I assume you can use the built in function and you just want to use it on strings? The function works on single characters. So since you have a string, you might do something like this untested. This just makes a new string and appends each character from the old string to the end of the new string, one at a time. Internally, the computer just knows that the data type is a char, and the value of this char is stored as a number between 0 and So the letter 'A', for example, is a char with a value of So basically you want to simply subtract 32 from all the values.
Of course, you don't want to perform the subtraction if the character is something non-alpha, like a space in between two words. So you want to perform that check to make sure it's in the range of lower case letters before you continue.

I know this should use the boolean operator, I'm just unsure as to how to implement it. I also know to encase the body in a while loop ending in "else if 'no' " for example.
