Instructions:

Please read the following instructions carefully before submitting assignment. It should be clear that your assignment will not get any credit if:

  • The assignment is submitted after due date.
  • The submitted assignment does not open or file is corrupt.
  • Assignment is copied(partial or full) from any source (websites, forums, students, etc)

Note: You have to upload only .cpp file. Assignment in any other format (extension) will not be accepted and will be awarded with zero marks. For example, if you submit code in .doc (Word document) or .txt files or .exe file, no reward will be given in any case.

Objective:

The objective of this assignment is to provide hands on experience of: 

  • Basic concepts of C/C++ classes and objects
  • Dealing with Data members and member functions
  • Initialization of objects
  • Constructor
  • Destructor
  • Dynamic memory Allocation using new operator.

Guidelines:

  • Code should be properly indented and well commented.
  • Follow C/C++ rules while writing variable names, function names etc
  • Use only dev-C++ for this assignment.

 

Assignment 

 

 

Problem Statement

Write a program using class(constructor, destructor, other member functions) to find the frequency of letters (small and capital alphabet or digit) from your student id character string. For example, frequency of letter ‘4’ in the string of a student id: “MC124514517” is 2.

 

Detailed Description:

You are required to write a program which contains a class myClass having the following data members:

 

         char*str,  alphabet;

and the following member functions:

  • myClass();
  • void setId(char *);
  • char * getId();
  • void countfunction();
  • ~myClass();

The main() function should create an object of myClass and through this object member functions are called one by one. When the object is created then constructor of myClass should dynamically allocate the memory using new operator for your VUID and displays a message after storing the default id in data member character pointer str.

     “Default Constructor is called and default id is MC123456789”

Similarly, setId() member function when called with your VUID passed as parameter, should set the value of data member character pointer str with your VUID.

getId() function should return the value of data member character pointer str to the main(), then following message with your VUID should be displayed:

      “Your ID is MC120403765”

Finally countfunction() must get input (any alphabet) from user by displaying the message,

     “Enter letter you want to count:”

Then this function counts frequency of the specified letter from your VUID and displays it.

Destructor at the end of the program should be called and display message:

“Destructor called… and object has destroyed”

Sample output of program:

i am sorry to bother you all at this time, but

i still have this

[Error] expected ';' before 'alphabet'

and i did not miss the ","

its written in the code as
-------------

private :
char*str,alphabet;
-------------

another error:

[Error] expected ';' before 'obj'

in this code line
cout"Your id is " obj.getId();
Please assist, 

thx in advance...
headers used as

#include<iostream>
#include<conio.h>
#include<string.h>

using namespace std;

 

its ok..nothing matter..

if u can this little pieces of error check me in pic format, may i can better analysis..

in 2nd error..i think..u missed double less than sign before obj.getId();

Attachments:

yes...m was right...just put double less than sign before obj.getId();

remove ur code here now...n check 1st error..

now this comes from no where :(

Attachments:

remove

#include<string.h>

n tell me again..

If I remove the:
#include<string.h>
than this error comes:

[Error] 'strcpy' was not declared in this scope

at this line
strcpy(str,id);

How can it possible??? 

can u upload ur C++ file here??

i check it..

Yes why not :)

Here it is

i hv downloaded ur file...

now,remove here immediately....

ur program is 100% working correct..

check it..
