Thank you for replying. What should I paste so you can get it?

I have updated question with "names.txt" content.

Hamza Jameel 1-May-22 14:52pm View

Yea fixed it by redeclaring array "int arr[n]"
Thanks :)

I am trying to create array of objects and then need to assign data to each object through array of data.All constructors are called after creating array of object. :). To assign data we need setdata function. then what is use of constructor here.

@CPallini Thankyou for helping out. I understand everything apart of logic behind declaring sum inside while loop. why can't declare it outside.

Hamza Jameel 23-Jan-22 11:55am View

@0x01AA Yes we need to make copy otherwise it won't work :D

No it doesn't work. it still gives the wrong check digit

You mean i should explain LUHN algorithm??
I don't enter any value it generate value itself

Hamza Jameel 23-Jan-22 9:32am View

@0x01AA my code follows LUHN Algortham step by steps. I checked it by printing that 16 digit array after every process. Without while loop (which checks that the number which we need to add in sum so it can be dividable by 10 is equal to checksum) it works perfectly. I tried running code again and again without while loop untill it generate a string whose that number is equal to checksum. then on checking on a card validator website it follows LUHN rules. Problem only occures when I try to do it with while loop so it can keep finding that number.

Solved Thanks

I broke up string and updated the code. I now have seperate numeric values but didn't get your hint to convert each one in int. To do math in numbers I have to convert them to int otherwise they show characters. I tried to use stoi() to convert to int but it is not working

Hi I broke the string using n[i]. Can you further guide me how to convert each in int array.

Hamza Jameel 15-Jan-22 7:45am View

It worked perfectly thanks!

Hamza Jameel 15-Jan-22 7:32am View

I fixed it but still getting same error.
updated the code

Thankyou so much. Solved :)

definitely 0.0/10.0 will show 0
but for example user answers 4 answers correctly the it will be 4.0/10.0. So it should show 0.4 instead of 0 as we are taking double data type :(

Hamza Jameel 5-Jan-22 13:28pm View

0.0(marks) divided by double total marks
0.0(whatever result) / 10.0

Hamza Jameel 5-Jan-22 13:22pm View

you can see code here
name and sapid can be anything.

[Error] invalid suffix "d" on integer constant

Hamza Jameel 5-Jan-22 13:15pm View

Hi. Thanks for replying. It works perfectly individually. But putting it along with other functions in my project it still shows 0. double marks has incremenet as user tells right answers.

Hamza Jameel 30-Dec-21 13:29pm View

Hi, Thanks for answering. it worked perfectly :)

Hamza Jameel 17-Oct-21 11:11am View
