Before we learn about logical operations, let's look at a few expressions in C programming. Suppose you need to identify the larger of two numbers (100 and 200). You will definitely say 200 is larger than 100, right? The question is, how did you get your answer? Yes, by comparing the numbers with each other. The condition is 100<200, or 200>100. The two symbols (< and >) are known as less than and greater than. Let's look at a few more expressions:
|
Expression |
Meaning |
|
x == y |
x is equal to y. |
|
x != y |
x is not equal to y. |
|
x < y |
x is less than y. |
|
x > y |
x is greater than y. |
|
x <= y |
x is less than or equal to y. |
|
x >= y |
x is greater than or equal to y. |
