$500 is deposited in an account which bears 12%p.a interest compound monthly. Use the compound interest formula to find the number of years it would take to accumulate $500 to $806.11
Under perfect competition the rising firms marginal cost curve above minimum of avarage variable cost is what?
Defi ne the concept of a supply schedule or curve. Show that an increase in supply means a rightward and downward shift of the supply curve. Contrast this with the rightward and upward shift of the demand curve implied by an increase in demand.
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.
Find the asymptotes of the curve 𝑥2𝑦 − 𝑥𝑦2 + 𝑥𝑦 + 𝑦2 + 𝑥 − 𝑦 = 0.
alex scored 90 during the first periodic exam in mathematics and 88 during the second periodic exam.The scores in first periodic exam ha a mean μ=83 and a standard deviation Ó=9.Scores in the second periodic exam ha av mean μ=8p and the standard deviation Ó=8.In which periodic exam was his standing better, assuming that the scores in his periodic exam are normally distributed?
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.
