Write a program in C++ that defines a class named StringOps. Declare data members of

this class as described below:

 variable str of data type string.

 variable size of data type integer which represents the length of the string str.

Write a program in C++ that defines a class named Student that represents a student. This

class declares three variables – name, stipend and course of suitable data types. It also has

a variable intern_status that is set to 1 if the student is interning in some organization and

0 otherwise. This variable is initialized appropriately in the constructors of the class. The

member functions of this class should be defined as given below:

 Parameterized constructor that initializes the values of all the members.

 An overloaded constructor that sets the stipend to zero for a non-interning student.

 Copy constructor for the class Student.

 Overload Operator << as a friend function in the class Student for displaying the

details of the student.

 Destructor for the class Student.

In the main() function, create two objects of this class; one for a ststuden

to create a new object and display it using << operator.

Write a program in C++ that reads text from the keyboard and stores it in a file named

“File1.txt”.

Also, for each of the specified prototypes given below, write the function definitions.

 void copyselc(ifstream& fp, ofstream& fp1):This function reads the

contents of the file “File1.txt” and copies those lines from the file that begin with

the character „#‟ to the file named “File2.txt”.

 void checksize(ifstream& fp1,ifstream& fp2):This function reads

two files “File1.txt” and “File2.txt” and counts the number of characters in

both the files. If the count of characters in both the files is same, then the function should

print the message “Both Files are of the same size” else it should display

“Size of the files is not same”.

 void dispNumNames(ifstream& fp):Assuming that the file “File2.txt”

may also contain numbers (1 to 5), this function will read the contents from the file and

display the number names for any numbers encountered.

Problem:

Create a Fraction class with two private positive integer member variables numerator and denominator, one

constructor with two integer parameters num and den with default values 0 and 1, one display function that

print out a fraction in the format numerator/denominator in the proper form such as 2/3 or ½ . Note: 2/4

should be displayed as ½.

You've learned in the past lessons on how to use square root functions, right? Then let's take your knowledge to the test. Print out the square root of a given integer with only two decimal places.

Ready, solve, and go!

Input

A line containing an integer.

4

Output

A line containing a decimal with two decimal places.

How to give values to the character array using maps

Develop a stopwatch with lap counter and total time calculator. The

program will create two processes and they will start calculating time.

One process will be used to calculate total time and the other will calculate

lap time. The total time calculator process will keep on calculating time.

In the lap time, calculator process when it reaches lap time limit, the

process will display lap number and set its counter to zero and start

calculating again. Take input of lap time and number of laps from the user

and start the program. At the end, display total time from total time

calculator process.
