What does ×= mean in C language?

The ×= operator in C language is used to multiply a variable by a certain value and store the result back into the variable itself. Its advantages include improving code efficiency. The specific syntax is variable = value;, this operation is equivalent to variable = variable value;, but is more concise and efficient.

×= operator in C language

In C programming language, ×=# The ## operator is a compound assignment operator used to multiply a variable by a value and store the result back into the variable itself.

Syntax:

variable *= value;

Working principle:

First,
• value will be Multiply the current value of variable variable.
Then, store the product result back into
• variable.

Example:

Suppose we have a variable

x with a value of 10. After executing the following code:

x *= 2;

, the value of

x will become 20. This is because:

• x's current value is 10.
10 multiplied by 2 gets 20.
• 20 is stored back to
• x.

Advantages:

Using the ×= operator is faster than performing the equivalent assignment operation because it combines assignment and multiplication into a single step. This can make your code more efficient, especially if you need to perform a lot of multiplication operations.

Note:

×= operator only applies to numeric variables. It cannot be used with characters or other types of variables.
