comma
Summary
The comma operator (,) causes two expressions to be executed sequentially.
Syntax
expression1 , expression2
- expression1
- Any expression.
- expression2
- Any expression.
Examples
The , operator causes the expressions to be executed in left-to-right order. A common use for the , operator is in the increment expression of a for loop. For example, the for statement allows only a single expression to be executed at the end of every pass through a loop. The , operator allows multiple expressions to be treated as a single expression, so both variables can be incremented.
j=25;
for (i = 0; i < 10; i++, j++)
{
k = i + j;
}
