Homework:
1. Write a C++ program that determines whether an integer number is
positive, negative or zero using the function test().
2. Write a C++ program that computes the shaded area in the figure
below using the function carea( ). The radius
values are entered by the user.
3. Write a C++ program that converts a positive integer number into
binary using the function binary().
4. An integer number is said to be a prime if it is divisible only by 1 and
itself. Write a C++ program that inputs an integer number and
determines whether the number is a prime or not using the function
isprime().
5. Write a C++ program to test if an entered character is a numeric digit
or not using the function isndigit(().
6. Write a C++ program that computes the number of decimal digits in
an entered positive integer number using the function nodec().
7. Write a C++ program that converts a small letter into capital letter
using the function tocapital( ).
8. Write a C++ program that inputs a time in seconds and then converts
the time from seconds into hours, minutes and seconds using the
function converttime( ). The program should then print the time in a
formal format (e.g. 12:59:59) using the function displaytime().
