How To Use Comma Operator In C

The comma operator represented by the token is a binary operator that evaluates its first operand and discards the result it then evaluates the second operand and returns this value and type.

How to use comma operator in c. In a c c program comma is used in two contexts. The value of rightmost expression becomes the value of the overall expression. Then in c programming either one of the operands is a floating point number a b 2 5 a d 2 5 c b 2 5 both operands are integers c d 2. In c and c comma can be used in two contexts. 1 comma as separator.

In the c and c programming languages the comma operator represented by the token is a binary operator that evaluates its first operand and discards the result and then evaluates the second operand and returns this value and type. There is a sequence point between these evaluations. In c programming language comma works as a separator and an operator too and its behaviour is little different according to the place where it is used. See this for more details. Comma works as an operator in program 2.

The comma operator is a binary operator that evaluates its first operand and then discards the result then evaluates the second operand and returns the value. The comma operator allows us to place one or more expression where c syntax allows only one expression. Precedence of comma operator is least in operator precedence table. Comma as an operator. Comma operator in programming languages like c c is a binary operator it is represented by token.

When a 9 is divided by b 4 the remainder is 1. 1 a separator 2 an operator. While declaration multiple variables and providing multiple arguments in a function comma works as a separator. The value of a comma separated list of expressions is the value of the right most expre. The operator can only be used with integers.

The comma operator has the lowest precedence in c or c. In the previous section of operator and expressions i had discussed about sizeof operator in c. Suppose a 5 0 b 2 0 c 5 and d 2. Today i am going to discuss about comma operator.
