Problem 1:
Implement
the functions with the prototypes below:
long square
(int number);
long cube (int
number);
The
function square returns the square of
the number passed as argument and the function cube returns the cube of the number passed as
argument to the function. The functions
are placed in the header file named lab6.h
Write
a program that prints the squares and cubes of the numbers from 0 to 10 in the
format shown below. The program includes the header file lab6.h and calls the
functions square and cube to calculate these
values.
Sample Output
|

0 0 0
1 1 1
2 4 8
3 9 27
4 16 64
5 25 125
6 36 216
7 49 343

Problem 2:
Implement
a function with the prototype below:
double
calRectangle(int option, double length, double width);
The
function returns the area of the rectangle if option is 1 and returns perimeter
of the rectangle for option value 2. The function is placed in the header file
named lab6.h
Write
a program that takes the length and width of a rectangle as input from console
and prints the area and perimeter of the rectangle. The program includes the
header file lab6.h and calls the function
calRectangle to calculate the area
and perimeter of the rectangle.
Hint:
Area of rectangle = length * width
Perimeter of rectangle = 2(length + width)
Sample Output
|
Enter length of the rectangle: 10
Enter width of the rectangle : 5
Area of the rectangle
= 50
Perimeter of the rectangle = 30

Problem 3:
Implement
the functions with the prototypes below:
int isOdd(int
number);
int isPrime(int
number);
int
isMultiple(int number1, int number2);
The
function isOdd returns 1 if the
number passed as input argument is odd otherwise it returns 0.
The
function isPrime returns 1 if the
number passed as input argument is prime otherwise it returns 0.
The
function isMultiple returns 1 if the
number passed as 1st input argument is a multiple of number passed
as 2nd input argument otherwise it returns 0. The functions are
placed in the header file named lab6.h
Write
a program that tests the functionality of the functions above as shown in the
format below. The program includes the header file lab6.h and calls the
functions above to determine if a number is even/odd OR if a number is prime or
not OR if a number is multiple of the other.
Sample Output
|
Enter 1 to test if a number is even or odd, 2 to test if the
number is prime and 3 to test if one number is multiple of other: 1
Enter number: 19
19 is an odd number.
Do you want to run this program again (y/n)? y
Enter 1 to test if a number is even or odd, 2 to test if the
number is prime and 3 to test if one number is multiple of other: 2
Enter number: 29
29 is a prime number.
Do you want to run this program again (y/n)? y
Enter 1 to test if a number is even or odd, 2 to test if the
number is prime and 3 to test if one number is multiple of other: 3
Enter first number: 15
Enter second number: 3
15 is a multiple of 3.
Do you want to run this program again (y/n)? n

Problem 4:
Implement
the function with the prototypes below:
double newSal
(double salary, double increment);
The
function newSal returns the new salary
of a person if the initial salary passed in 1st argument increases
by the %age value passed in 2nd argument. The function is placed in
the header file named lab6.h
Write
a program that takes the current salary of a person as input from console and prints
the salary table below after 1st, 2nd, 3rd, 4th
and 5th year assuming that the salary increases at rate 5%, 6%, 7%,
8%, 9% and 10% every year. The program includes the header file lab6.h and calls the
function newSal to calculate these
values.
Sample Output
|
Enter salary: 10000
1
Year 2Years 3Years 4Years 5Years
5% 10500.00 11025 11576.25 12155.06 12762.82
6% 10600 11236 11910.16 12624.77 13382.26
7% … … … … …
8% … … … … …
9% … … … … …
10% … … … … …

Problem 5:
Implement
the function with the prototypes below:
void translate
(long);
The
function translate takes in a number as
input argument and prints it in words. You can also develop other functions that
can be called from this function to reduce repetition of code. The functions are
placed in the header file named lab6.h
Write
a program that takes a number as input from console and translates it into
words. The program includes the header file lab6.h and calls the function translate to translate the
number into words.
Sample Output
|
Enter the a number: 2147483647
You entered two billion one hundred forty seven million four
hundred eighty three thousand six hundred forty seven
|
Problem 6:
Implement
the function with the prototypes below:
long power (int
x, int y);
The
function power takes in two integers
as arguments and returns xy. The function uses the recursion
algorithm for implementation and is placed in the header file named lab6.h
Write
a program that reads x and y as integers from console. The program includes the
header file lab6.h and calculates x ^ y
by calling the function above and prints in the format shown below:
Sample Output
|
Enter x: 2
Enter y: 3
2 ^ 3 = 8
|
Problem 7:
Implement
the function with the prototypes below:
long timeInSec
(int hour, int min, int sec);
The
function takes three integer arguments (hours, minutes and seconds) and returns
the number of seconds since the last time the clock struck 12.
Write
a program that uses this function to calculate the amount of time in seconds
between two times both of which are within a 12 hour cycle of clock. The
program includes the header file lab6.h
Problem 8:
Implement
the function with the prototypes below:
int isPerfect
(int number);
The
function returns 1 if the number passed as input argument is a perfect number
otherwise it returns 0. An integer is said to a perfect number if the sum of
its factors including 1 (but not the number itself) is equal to the number.
e.g., 6 is a perfect number since 6 = 1 + 2 + 3. The function is placed in the
header file named lab6.h
Write
a program that uses this function to print all the perfect numbers between 1
and 1000. The program includes the
header file lab6.h
Problem 9:
Implement
the function with the prototype below:
int gcd (int
number1, int number2);
The
function returns the greatest common divisor of two numbers passed as input
arguments The greatest common divisor
(GCD) is the largest integer that divides the two integers. The function is
placed in the header file named lab6.h
Write
a program that reads in two numbers from console and uses this function to
calculate and print the greatest common divisor of the two numbers. The program
includes the header file lab6.h
Problem 10:
Implement
the function with the prototype below:
char grade (int
number);
void gradeDescription
(char grade);
double gpa(char
grade);
The
function grade takes in the marks in
a course as input argument and returns the grade of a student as per rules in
the grading table below.
The
function gradeDescription takes in the grade in
a course as input argument and prints a description of the grade as mentioned
in the grading table below.
The
function gpa takes in the grade in
a course as input argument and returns the grade point average (GPA) of a
student in that course as per rules in the grading table below.
Write
a program that reads in the marks in a course. The program includes the header
file lab6.h and calculates and prints
the grade, grade point average and grade description by calling the respective
functions in the format shown below:
Sample Output
|
Enter marks in a course (0-100): 76
