4. (Prime Numbers) An integer is said to be prime if it is divisible by only 1 and itself. For example, 2, 3, 5 and 7
are prime, but 4, 6, 8 and 9 are not.
Write a function called isPrime that receives an integer and determines whether the integer is prime or not.
Write a test program that uses isPrime to determine and prints all the prime numbers between 1 and 1000.
Display 10 numbers per line.
(C++ language)
Q2) (Perfect Numbers) An integer number is said to be a perfect number if its factors,
including 1 (but not the number itself), sum to the number. For example, 6 is a perfect
number because 6 = 1 + 2 + 3. Write a function 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. Print the factors of each perfect number to confirm that the
number is indeed perfect. Challenge the power of your computer by testing numbers much
larger than 1000.
