String Substitution

tum_twish · **Posted:** Thu Apr 17, 2003 9:58 am

I have string that displays the sum of various numbers. The string is concatenated in a loop. However, at the end of the calculation, an extra "+" displays. How can I remove that plus sign?

ie.

2+5+7+9+10+=33

How do I remove the last + sign? Thanx.

maybe you're just exiting the loop too late.
try exiting the loop sooner so that the "+" wont show up at the end of your equation

code:

function Sum_Of_The_Proper_Factors (I_number : int, B_flag : boolean) : int

%This function calculates the sum of the proper factors of a number
%The function requires the number
%The function returns the sum of proper factors back.

var I_sum : int := 0
S_factorsString := ""
for I_factor : 1 .. (I_number - 1)
if I_number mod I_factor = 0 then
I_sum := I_sum + I_factor
S_factorsString := S_factorsString + intstr (I_factor) + "+"
end if
end for
result I_sum
end Sum_Of_The_Proper_Factors

S_sumOfFactorsString := intstr (Sum_Of_The_Proper_Factors (I_number,
B_flag))
GUI.SetText (I_factorsOutput, S_factorsString + "=" +
S_sumOfFactorsString)

please, if you are having problems with code or anything like that, please post the code... or even give an example of what you want... in your case the example wont help much so please post the code...

im not good at programming, but logically speaking, y dont u just forget about displaying the "+"s?
u can put a space or sumthing instead Very Happy

you can use substrings to get rid of the last character (the unwanted +)

word := word(1..*-1)

then you add "= whatever"

Or, don't append the plus sign... do an if statement for it

code:

for I_factor : 1 .. (I_number - 1)
if I_number mod I_factor = 0 then
I_sum := I_sum + I_factor
S_factorsString := S_factorsString + intstr (I_factor)
%--
if I_factor (notequal) I_Number - 1 then
S_factorsString := S_factorsString + "+"
end if
%--
end if
end for

notequal: I forgot the operator for it. ~=?
