"Auto-increment" usually refers to automatically incrementing a field in a table to the next integer. This is usually used to create a unique key value for a record. The computer automatically puts the next value in the key field as soon as the record is created, so the user doesn't need to worry about that housekeeping feature.

Can you increment the value of a variable by 2 using any increment operator?
There is no such increment operator in C language to increment the value of a variable by 2.An increment operator only increments the value by 1. however you can apply the increment operator twice to get an increment of 3. No: you cannot: ++(++a) won't compile. Yes. Example: a += 2; but += is not an increment operator, it's a shorthand of a=a+2; just like a++ is a shorthand for a= a+1
