Solution 1

Try changing,

a = remove(name);

to

a = remove("the_file_name"); //"the_file_name" is the name of the file you want to delete.

Maybe this[^] link can add more clarification.

Thank you for making my code to work but the output always goes for the else part of the program even if the file is present.Can you help me with this.

jeron1 3-Oct-15 11:50am

How are specifying the file name (path).

[no name] 3-Oct-15 12:11pm

a = remove("c:\test.txt");

jeron1 4-Oct-15 8:24am

Try "c:\\test.txt" instead.

[no name] 4-Oct-15 9:19am

Thank you for this.

jeron1 4-Oct-15 10:30am

This is called an escape sequence, check out this link "http://www.cplusplus.com/forum/beginner/86189/" for a discussion and good links regarding them.

[no name] 4-Oct-15 13:28pm

Thank you once again.I have registered my name with the help of your link but I don't know how to start a discussion can you please help me with this.

jeron1 5-Oct-15 11:25am

I don't really think that you need to post a question there. Do you have a book on c or c++? Escape sequences are pretty basic when it comes to inputting and outputting text. Here are a couple of links to threads here at code project which discuss them,
"http://www.codeproject.com/Messages/3310946/need-delete-a-file-in-vcplusplus.aspx"

and "http://www.codeproject.com/Messages/4086314/Escape-out-double-quote.aspx". I am certain that there are many others as well, but a good book will do the most good.

[no name] 5-Oct-15 11:45am

For C I am using "The experts edition of the C programming language by Harry H.Chaudry" and for c++ I use "object oriented programming with c++" by a local author. can you suggest me better books/books you use.

jeron1 5-Oct-15 12:21pm

Take a look where printf() and formatting is discussed in the C book, there has to be mentions of escape characters. This link "http://www.codeproject.com/Questions/305031/What-are-the-best-books-on-Programming-Cplusplus" lists some good books on c++ programming. This link "http://www.cprogramming.com/tutorial/printf-format-strings.html" has some good visuals regarding formatting.

[no name] 5-Oct-15 13:43pm

Thank You for this.But there are many reference books in the article for c plus plus programming.It is so much better if you say the specific book which you use for C++ programming.Thank you once again.

jeron1 5-Oct-15 17:27pm

How about a couple of free ebooks, see this link.
"http://www.mindview.net/Books/TICPP/ThinkingInCPP2e.html"

[no name] 6-Oct-15 10:31am

Thank you once again for this free e-book.I have downloaded the two zip files and extracted successfully.I extracted my first folder and the extracted folder contains many sub-folders C02,C03, etc., and what is it.I am clear with the second folder.Please help me with the first folder.

jeron1 6-Oct-15 11:46am

These folders look to contain small programs designed to show you different things about the c++ language. They are referenced in the text for use as exercises, you'll do well by trying to understand every line of code. "C02" means these are referenced in chapter 2, "C03" means these are referenced in chapter 2, etc.

[no name] 6-Oct-15 12:28pm

These examples are very much useful to me.A millions of thank you once again.
Sir,Even though this is not related to topic I was forced to ask this question to you.I have completed c, c++ with an excellent grade and received a certificate form a nearby institute but The cerfication was not an international certificate.In order to get an international certificate what should I do.I have searched this in Google but Did not get the proper result.Since you are professional in this field I believe that you can help me.Sir, kindly excuse me for my English since English is not my first language and for asking out of topic questions.Forgive me kindly if anything is wrong in it.

jeron1 6-Oct-15 12:49pm

Sorry I'm not familiar with any international certification for c,c++. At best (as far as I know) you could try getting a diploma from an accredited institution. Having said that, many pogrammers better than I don't have that 'official schooling' diploma (certificate) as they are mostly self taught. People interview them to gain knowledge of thier problem solving skills and knowledge of certain technologies and languages. These people are hired based on the results of the interview(s), not necessarily on what grades they got in school. There are great self taught programmers and there are lousy 'educated' programmers. I do have to ask though, the institute you went to didn't teach you about escape characters? These are really basic concepts in c, c++.

[no name] 6-Oct-15 13:11pm

A good learner should not blame anyone even though his notes say nothing about it.It's me my responsibility to gain additional knowledge by referring to additional notes/books which is not provided by the institution.It's all my fault.But I am just 17 years old and I have a strong determination and will to expert all programming languages within my lifetime and I believe that I could be professional at your age.Pardon me If any wrong.And Thank you for the additional notes.

jeron1 6-Oct-15 13:37pm

I didn't mean to be critical of you, my apologies if you took it that way. But I have to disagree in this case, I believe basic formatting, among other things, must be taught in class. Often the students are beginners and don't know where to look or what to look for. For more advanced concepts as the students get more comfortable with the language, then yes they would do well to look at other resources, but in the very beginning that's asking too much in my opinion.

[no name] 6-Oct-15 14:23pm

There is nothing to apologize Sir.You are not responsible for my fault.
Neither my notes and the printed stuff given to me by the institution says nothing about it(escape characters) but the book which I personally use mention about it(\\ for backslash) so finally it's my fault.Sorry if I made you to feel pity of me.

[no name] 10-Oct-15 23:33pm

Sorry Sir I do not know where to ask this question and I searched for this in help session also but I could not find it.Even-though I have posted my answer and my answer has been up-voted my point does not increase.What should I do Sir?.Kindly excuse me for disturbing you.

jeron1 12-Oct-15 10:30am

"http://www.codeproject.com/suggestions.aspx" This (Bugs & Suggs) is where one would ask.

[no name] 13-Oct-15 3:01am

Thank you Sir for your kind help.Please excuse me for the disturbance.
