Then after drawing a comparison I will discuss the roles of enums, or enumerations, and give some examples on how they are useful, and why they are called constants. The for Loop The standard for loop can be used for many things, but in this example below I will be using the for loop to iterate through and print each element of an array. In the example, the variable x is initialized as an array, the array is then assigned the value of ²ve elements, then each of those elements is assigned random four-digit numbers to represent years. The for loop then uses incrementation to iterate through each array element of x. It starts at position 0, then works its way through the array with the help of the count++; statement that increments the variable count each time the loop runs. Then once count is equal to the length of elements in the array the for loop will stop. This results in the printing of each of the elements contained within the array. This demonstrates that the for loop runs for every time that variable count is not equal to the length of elements within the array. So when the loop ends, and it goes to start again if the loop condition returns true, such as count not being equal to the length of the array it will run, but if it is false it will not run (Programiz.com, n.d.).

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
