Using the tenary operator in C with 3 numbers - Kernelpanic - 08-08-2024
The tenary operator was discussed here for some time ago, a bit complicated in Basic. It is quite useful for simple comparisons.
The program uses the tenary operator in C with a triple comparison. It also works with four numbers, but that gets a bit confusing. If one only want to compare two numbers, simply enter 0 for the third number. -- Both files in the same directory.

For those of you who missed out watching reruns of Hogan's Heroes, the tenary operator is basically saying...
if a then b otherwise c
Which looks to me like the BASIC equivalent of our if/then/else statements.
But then again, I could be channeling Sergent Schultz, in which case, "I know nothing, nothing!"

the difference is that you can assign the ternary expression to a variable, you can basically do the same with if then else, but sometimes you can simplify things by using the ternary expression, but I confess that the ternary operator looks weird unless you use it a lot

I look at it as shorthand...
C=(A>B)?A:B;
meaning:
If A > B Then C = A Else C = B

Code: (Select All)
a = 5
b = 4
c = 7
If a > b Then
c = a
Else
c = b
End If
Print c
There c would have to be the largest number, right?

You can't assign c.

Must be under this new, modern grading system. A, B, D, E, F ??

This one was fun...
Code: (Select All)
Age = 30
Beverage = Age >= 21 ? "Beer" : "Juice";
Results: BeerSo you don't assign beverage, it is determined by the assigned value of age.

spell it right.
(not being a jerk. but i thought the word started with "ter" which got me to look it up.)

I think the Kernel was using the 8th instance of the function as in...
I'm tenary the eighth I am
Tenary the 8th I am I am
I got called from the mainframe next door
It's been booted seven times before
And every call was a tenary, it couldn't call a driver or a cam
I'm the eighth old function tenary
Tenary the eighth I am
