Tips to get pass mark in Anna university semester examinations :

                Hi and hello poor innocent guys over there .... This is me one of the Engineering student under so called Anna university as like you guys..

                    I finished my degree without any history of arrear that means no arrear in each semester pulse I got placed in the campus itself so here I am to share my success tips to over come the Anna university semester exams..

                      Look guys Anna university is the easiest and simple place where one can get pass with little effect and smart work. The first and the for most likely important thing to do is please for God sake keep your internal make up to 14 because it help you to get through. Don't worry if you don't have much, 10 is more than enough. I cleared all semester with internals 10.

                        For 16 mark questions please refer the previous year questions.
Study only those that repeat. Two 16 mark question from each unit will make.

                        For 2 marks read only those that are in the question bank book. This will make. Please don't ignore 2 mark question from reading this is so needed if you wish to get passed.

                          Then the last thing, just fu*k the seat and sit for the exam let the fate decide......

                  
          

Life as an Engineering Student..... Dreaming huge....

Bla bla bla... have heard so much about the dreams the struggles of many engineering guys out there.. Its not that easy to be a engineer as you all guys non-engineers think off.. me myself an engineering student from the a university were lakhs of students fall. Here is how their life starts.
                                                                             Its their Daddy's OMG who make them to join 3 to 4 tuition's during their 11th and 12th waking up 3.30 am in the mid night not early morning you shits.. when they reach there, there comes the midnight test in the tuition which was useless and the results of the previous test will be shown immediately after today's test ... here come the fun part those who fail in that are asked to stay out side the tuition that is they provide a special area for those special guys like us and are made to write those test questions with answer 15 times while the tuition goes on inside, we keep on writing.. so it was like waking up early in the morning for assignment training.....LOL
                          Finally came the public exam results... To be continued

Amazing Spider-Man 2 Review:

C Program for the Implementation of a Simple Text Editor with featuress like Insertion, Deletion | CS1207 - System Software Laboratory

AIM:
      To write a "C" program to implement "Text Editor" with features like insertion, deletion in CS1207 - System Software Lab.

ALGORITHM:

1.Display options new, open and exit and get choice.
2.If choice is 1 , call Create() function.
3.If choice is 2, call Display() function.
4.If choice is 3, call Append() function.
5.If choice is 4, call Delete() function.
6.If choice is 5, call Display() function.
7.Create()
    7.1 Get the file name and open it in write mode.

    7.2 Get the text from the user to write it.
8.Display()
    8.1 Get the file name from user.
    8.2 Check whether the file is present or not.
    8.2 If present then display the contents of the file.
9.Append()
    9.1 Get the file name from user.
    9.2 Check whether the file is present or not.
    9.3 If present then append the file by getting the text to add with the existing file.
10. Delete()
    10.1 Get the file name from user.
    10.2 Check whether the file is present or not.
    10.3 If present then delete the existing file.
