Comma operator (,)

Operation

Executes two expressions sequentially.

expression1, expression2

Parameters

Expression1

Any expression .

Expression2

Any expression.

Description

, the operator causes the expressions on both sides of it to be executed from left to right, and gets the value of the right expression. , the most common use of an operator is in an increment expression for a for loop. For example:

for (i = 0; i < 10; i++, j++){k = i + j;}

Each time the end of the loop is passed, the For statement allows only a single expression to be executed. , an operator is used to circumvent the restriction by allowing multiple expressions to be treated as a single expression.
