4. (Factors of Integers) Write a pseudocode and C++ program that reads an integer and displays all its smallest factors in increasing order. Hint: You should start by dividing the number by a factor ( 2 is the starting factor). For example, if the input is 120 , then 120=260. Then, take 60 and divide it by 2,60=230. When the number is not divisible by 2 , increment the factor. So, the factors of 120 should be: 2,2,2,3,5..
