Hey Guys,, I did this coding .. but when ever i add data it doesn't save the data, and when i add second time the data it does. Even when i try to delete any thing the file gets corrupted. Sorry i cant copy the whole code here. It a big file. So i have attached my CPP file.. PLease help me .. and NOTE: I am asking help for my homework assignment, but I have done this much coding. But i cant catch the error. That why i am asking for help. Thanks in Advance, Anshu Verma
You have not attached the file and also for your knowledge the limit is to 100k characters and so I am sure you can post the code here

What input do you give the program? Can you upload a screen shot (ideally just paste text in rather than posting a graphic) showing the input and output?
Take an Example of Murder I Enter Every thing its asks for ... I put every text.. but when i go display option or search or delte option.. its say NO record found.. and when i see txt file where it stores murder records it comes as: Anshu ch program.

> I Enter Every thing its asks for Yep, but what you you actually enter? Let me clarify. The code isn't everything. The contents of the variables are relevant too. And these depend on what you enter. So not giving any input is as useful as only giving us part of the code (i.e. not at all). Also if you show the output (and explain why it is wrong, i.e. what you expected it to show) then that makes debugging not just easier but possible. So there's no point me even starting to look at the code unless I have some idea what it's likely to do, and that depends critically on what input you give it. One thing you could try is to add some debugging printf statements to the code that show you where it's up to, what the value of certain variables are and which way it goes at if statements. This kind of tracing can be very useful in debugging. Actually it's about a bazillion times easier with a debugger cos you can just step through the code as it's executing and see where it goes wrong.
Hey, I have uploaded the files. input.jpg - for what i have inputed display.jpg - when i choose an option to display search.jpg - Which i search with name "XYZ" delete.jpg - to delete the record with the name "XYZ" please have look at them.
Hey really sorry i couldnt understand this line debugging printf statements to the code how can go about that? Thanks
Add a printf statement that prints something useful, e.g. Code: printf("Please enter a number: "); char buf[32]; fgets(buf,30,stdin); int n=atoi(buf); printf("DEBUG: you entered %d\n",n); So you can check the conversion was done properly and the program will continue with the expected value of n. Applying that to your program then, you might want to print the contents of the murder object immediately after it was brought back from the file.
