    allocation and reallocation of memory dynamically of an integer array

    Write a program in which you have to:
    1. Dynamically allocate an array of integers.
    2. Take array size as input from user and allocate memory according to this size.
    3. Take values of array elements as an input from user.
    4. Print all array values.
    5. In this step; double the previous array size (taken in step 2) and reallocate memory for the array according to new array size. For example if user provided array size is 4; now it will become 8, i.e. allocate memory for array having size 8.

    6. Now again take values for second half of the array as an input from the user to fill the increased size of an array.(You have already taken the values of first half of the array elements in step 3, now take values for remaining elements i.e. Second half).
    7. Print all values of the array.
    8. Also confirm that first half values of array are same in both printout statements (step 3 and step 7).


    Sample Output
    Program to dynamically Allocates an array of integers.
    Enter the size of the array: 4
    Enter a value: 1
    Enter a value: 2
    Enter a value: 3
    Enter a value: 4


    The elements of the array are:
    1 2 3 4

    Enter the elements in the array after reallocation:
    Enter a value: 5
    Enter a value: 6
    Enter a value: 7
    Enter a value: 8

    And what have you done of that, and what have you got problems with?

    It's no good posting your assignment here, we do not do other people's homework. The way it works is that you show us that you are TRYING to solve it yourself, and we help you a bit at a time.

    Every time I see a post like this, with just the assignment and maybe a "do this for me" or similar message, I think of Back to the Future; Biff, complaining that he has to have time to re-write the report in his own handwriting.....

    Every time I see a post like that, I can imagine the OP saying "Do you want fries with that?"

    Right, you obviously didn't understand the first reply, so I will be a bit more direct and clear:
    1. You post the code you have at the moment.
    2. You tell us exactly what you have a problem with
    is it compiling or not, if not what error messages;
    is it crashing, what do you need to do to make it crash;
    is it producing a different result than you expect, what does it produce, and what do you expect

    We do not "do" other peoples homework. It is unethical to do that, and whilst YOU may not care, we do get to work with the people that come out of the schools, and if all those people know how to do is go on the internet and ask someone else to do it for them, it's not going to be good!

    Restrict user to enter only numeric entries

    Hi,


    I need to know about how to restrict users to enter only numeric entries only and when the user enter the alphabetic character it exit the loop. I want to use the function for it.

    I want to use it while getting the input of getting the size of array from user. If a user enter the alphabetic entry it doesn't execute the function and ask again for the numeric entry.

    Regards

    Dunno the meaning of your because

    Well, If cudn't get the meaning of your because here.

    & if you are saying that why I haven't posted my code here, is because of the reason that I had made it with hard work & it's the same assignment about which the query is already posted here, so I don't want any one other to copy my assignment. Once the date for that assignment will be over i'll copy the code too.

    Therefore i only queried for the loop here. I think this explanation is enough for your because. Need more explanations kindly post.

    Regards

    Obviously trying as hard at programming as at English, and I'm sure that English is this person's first language, as evidenced by things like "Dunno".
    I get the feeling that the education system has gone downhill lately.

    Rule of Proper Grammar

    Well iMalc or whatever your name is, this is the dilemma of the nation that they relate bieng Educated with the person who know English well and dunno (for your convenience don't know) the manners.

    Kindly let me know where is it written that English is mandatory to be the part of this forum & better make your decisions on some concrete points rather than assumptions.

    I am not the same user & if I have to ask anything I have the guts to ask it open rather than hiding myself with different user names.

    I joined this forum because i like people here don't make other people just copy the stuff but help them for good. But I am sorry to see that people here just mean to insult the others rather than bieng cooperative.

    And yes have the English teaching classes for the users here so that they can come up to your expectations (the educated people)

    Regards,

    your post is making my eyes bleed, please pay attention to the red underline (not like that will fix half your problems though)

    Then make your own dam thread

    bieng
    should be being

    that they
    "that" should be "where"

    the person who know English well
    can be replaced with "knowing English well"

    & better make your decisions
    that sentence is a run on sentence because it has two topics.
    "better" doesn't belong there

    i like people here don't
    "I like how the people here don't" conveys your point better
