Detailed Syllabus

1. String concatenation using dynamic memory allocation concept
Aim
To implement the string concatenation function by using dynamic memory
allocation concept.
Objective
To concatenate two or more strings into one string by allocating memory to objects at the time of their construction.

Exercises

1. Create class STRING with two constructors. The first is an empty constructor, which allows declaring an array of strings. The second constructor initializes the length of the strings, and allocates necessary space for the string to be stored and creates the string itself.

2. Create a member function to concatenate two strings.

3. Estimate the combined length of the strings to be joined and allocates memory for the combined string using new operator and then creates the same using the string functions strcpy() and strcat().

4. Display the concatenated string.

2. Implementation of arithmetic operations on complex numbers using
constructor overloading

Aim
To implement arithmetic operations on complex numbers using constructor overloading

Objective
To represent complex numbers and to perform arithmetic operations on complex numbers using overloaded constructors in a class.

Exercises

1. Create class COMPLEX with three constructor to perform constructor overloading. The first constructor takes no arguments which is used to create objects which are not initialized.the second takes one argument which is used to create objects and initialize them and the third takes two arguments which is also used to create objects and initialize them to specific values.

2. Declare friend function.

4. Overload arithmetic operators +,-,*,/ to perform arithmetic operations on the complex numbers.

5. Display the results of each arithmetic operations.

2. To read a value of distance from one object and add with a value in another object using friend function

Aim
To read a value of distance from one object and add with a value in another object using friend function.

Objective
To create two classes and store the values of distance and to read the value from one class and add with a value in another object using friend function.

Exercises
1. Create two classes AB and AC and store the value of distances.

2. Declare friend function.

3. Read the value from the classes.

4. Perform addition to add one object of AB with another object of AC.

5. Display the result of addition.

4. Implementation of + and - operator overloading and implementation of addition operation of octal object with integer using operator overloading

Aim
To implement + and – operator overloading and to implement addition operation of octal object with integer using operator overloading.

Objective
To display the number of days between two valid dates and the date after a number of days from a valid date by overloading the operators + and -.
To represent octal numbers and to add an octal object with integer by overloading operator ‘+’.

Exercises
1. Create a class called DATE and define two member functions get-data and
display-result.

2. Accept two valid dates in the form of dd/mm/yyyy using get-data.

3. Overload operators + and – to display the number of days between two valid dates using display-result.

4. Repeat step 3 to display the date after a number of days from a valid date using display-result.

1. Create class OCTAL for representing octal numbers.

2. Create a constructor to implement OCTAL h=x where x is an integer.
3. Overload operator ‘+’ to perform the integer addition with an OCTAL object like int y= h+k (where h is an OCTAL object and k is an integer).

4. Display the resultant integer value y.

5. Implementation of addition and subtraction of two polynomial objects using
operator overloading

Aim
To implement addition and subtraction operations of two polynomials and display using << operator overloading. Objective To add and subtract two POLYNOMIAL objects and to display results by overloading the operator <<. Exercises 1. Create a class called POLYNOMIAL with constructors to create polynomial objects and to initialize with specific values. 2. Create member functions to perform addition and subtraction of two polynomials. 3. Overload operator << to display the results of addition and subtraction operations on two polynomials. 4. Display the results. Software Equipment Required TURBO C++ - 30 nodes Hardware Equipment Required PC - 30 nos 6. Managing bank account using inheritance concept Aim To manage the account information of the customer using inheritance concept.
