Where:

• variable is the variable to be incremented.

a++; // a 现在是 6</code>

and the prefix increment operator a:

• Increment timing: Suffix increment is incremented after the value is taken, while prefix increment is incremented before the value is taken.
• Return value: Suffix increment returns the incremented value (a 1), while prefix increment directly returns the incremented variable value.
