What is the difference between = and ==?
Short answer. == compares two values; = stores a value.
Which group gives true or false?
The relational and logical groups.
Four groups
| Group | Examples |
|---|---|
| Arithmetic | + - * / % |
| Relational | == != > < |
| Logical | && OR ! |
| Assignment | = += |
Remember
| == compares |
| = stores |
One equals sign or two? Mixing them is a classic mistake. Four groups. Arithmetic does maths. Relational compares, with double equals. Logical means and, or, not. Single equals stores. Double equals compares. Single equals stores.
