Summary
This document provides guidance on how to correctly compare values in statements. It will also go over common misconceptions and how to avoid them and give a few practical examples.
What Exactly Are Values?
Values are the numbers, words, and symbols that are being compared in a statement. For example, one might compare the value of 4 to the value of 5 in order to determine which is greater.
How to Compare Values
The key to comparing values is to determine what types of values are being compared and using a logical approach that makes sense for those types. Here are a few examples:
Examples
- Comparing Integers
If you are dealing with integers, the integer with the greater magnitude (larger absolute value) is the greater one. For example, 4 is greater than -5. - Comparing Strings
When strings are compared, the comparison starts at the beginning of the string, comparing characters in order of their place in the string until something different is found. In other words, the character that appears first in the alphabet is the lesser character. For example, "dog" is lesser than "cat". - Comparing Symbols
Symbols are usually compared based on the values they represent. For example, the value 5 is greater than the value 4.
Common Misconceptions
It is important to remember that values must always be compared based on their type. For example, just because one character appears later in the alphabet than another does not mean that it is the greater one. This can be confusing when comparing strings, so it's important to remember that strings are actually compared based on their place in the string and not their place in the alphabet.
Another common misconception is that the value with the higher magnitude is always the greater one, even when dealing with strings. This is not true; strings must still be compared based on the characters within the string.
Conclusion
In conclusion, understanding how to compare values is quite simple. All you have to do is examine the type of values that are being compared and compare them using the logical approach that makes sense for those types. Keep in mind that strings are not compared based on how they appear in the alphabet, and it is important to remember this when dealing with strings.
