Define a function that returns the product of two numbers entered by user.
3.
Write a program to print the circumference and area of a circle of radius entered by user by defining your own function.
#include<iostream>usingnamespacestd;voidcircle(intradius){cout<<"Perimeter is "<<2*3.14*radius<<"\n";cout<<"Area is "<<3.14*radius*radius<<"\n";}intmain(){circle(4);return0;}
4.
Define two functions to print the maximum and the minimum number respectively among three numbers entered by user.
5.
Define a program to find out whether a given number is even or odd.
Write a program which will ask the user to enter his/her marks (out of 100). Define a function that will display grades according to the marks entered as below:
Marks Grade
91-100 AA
81-90 AB
71-80 BB
61-70 BC
51-60 CD
41-50 DD
<=40 Fail
9.
Write a program to print the factorial of a number by defining a function named 'Factorial'. Factorial of any number n is represented by n! and is equal to 1*2*3*....*(n-1)*n. E.g.- 4! = 1*2*3*4 = 24 3! = 3*2*1 = 6 2! = 2*1 = 2 Also, 1! = 1 0! = 0
Define a function to print the prime factors of a number.
3.
Using recursion, define a function to know nth term of a Fibonacci series.
Nth term of Fibonacci series is
F(n) = F(n-1)+F(n-2)
F(0) = 0
F(1) = 1
F(2) = F(1)+F(0) = 1+0 = 1
F(3) = F(2)+F(1) = 1+1 = 2
F(4) = F(3)+F(2) = 2+1 = 3
Define a function named 'perfect' that determines if parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1 and 1000.
[An integer number is said to be "perfect number" if its factors, including 1(but not the number itself), sum to the number. E.g., 6 is a perfect number because 6=1+2+3].
5.
Define a function to calculate power of a number raised to other i.e. ab using recursion where the numbers 'a' and 'b' are to be entered by the user
Write a program that takes as input your gross salary and your total saving and uses another function named taxCalculator() to calculate your tax. The taxCalculator()
function takes as parameters the gross salary as well as the total savings amount. The
tax is calculated as follows:
(a) The savings is deducted from the gross income to calculate the taxable income. Maximum deduction of savings can be Rs. 100,000, even though the amount can be more than this.
(b) For up to 100,000 as taxable income the tax is 0 (Slab 0); beyond 100,000 to
200,000 tax is 10% of the difference above 100,000 (Slab 1); beyond 200,000 up to
500,000 the net tax is the tax calculated from Slab 0 and Slab 1 and then 20% of
the taxable income exceeding 200,000 (Slab 2); if its more than 500,000, then the
tax is tax from Slab 0, Slab 1, Slab 2 and 30% of the amount exceeding 500,000.
7.
Write a function that takes your date of birth in YYYY, MM and DD format (separated
by spaces) as input as well as the current date, in same format, and calculates your age
in years, months and days. You must check for leap years also. Write a separate function
to check for leap year.
