Hi there everyone, recently I have started my internship at an IT department at a company.
Now I have a little assignment where I have to make some assignments in KiXtart. But even on the first "sheet" I have run into some problems I just can't figure out.
I have to create a function that can multiply/divide/add/subtract integers and then load them in the variable.
But I just can't add the right parameter to make a distinction between what to do.
My guess is that I have to declare the different parameters so it knows what to do. But I just can't figure it out.
Code:
$var2 = som2(1,8,"+")
? "var= " + $var2
Function som2($num1, $num2,"+","-","*","/")
Dim $num3
Dim $num2
Dim $num1
"+" = +
Select Case
Case $som2 = $num1 "+" $num2
$num1 + $num2
EndSelect
EndFunction
Could someone guide me in the right direction, but not spoil the whole assignment?

You need to specify the operator when calling the function. The function itself should check what operator (-, +, / or *) is needed and act accordingly. The outcome can be stuffed into a variable with the same name as the function so you get some data from the function.
Best practice would be to dim all used variables inside the function except the ones used as parameters for the function. A check if all parameters are like they should be (integer and the used operators) would also be great to avoid unexpected results like add 1 to 8 resulting in 81 instead of 9.
If you are totally stuck and there is absolutely no way out check out the spoiler I added. Working example and not best practice coding but it will get you somewhere. Try to write it yourself first
Warning, Spoiler:
Code:
Break on
$var2 = Math(1,8,"add")
? "var = " + $var2
Function Math($num1, $num2, $operator)
Select
Case $operator = "add"
$math = $num1 + $num2
Case $operator = "divide"
$math = $num1 / $num2
Case $operator = "multiply"
$math = $num1 * $num2
Case $operator = "subtract"
$math = $num1 - $num2
EndSelect
EndFunction
