what is meaning of product *= in c

The *= operator in C is called the multiplication assignment operator. It is used to multiply the value on the left-hand side of the operator by the value on the right-hand side, and then assign the result back to the left-hand side.

Here is an explanation of each step involved when using the *= operator:

1. The value on the left-hand side of the *= operator is multiplied by the value on the right-hand side.
2. The result of the multiplication is then assigned back to the left-hand side.

For example, consider the following code snippet:

int x = 5;
int y = 2;
x *= y;

In this example, the value of x is initially 5, and the value of y is 2. After the x *= y operation, the value of x will be updated to the result of multiplying 5 by 2, which is 10.

So, the *= operator is a shorthand way of performing multiplication and assignment in a single step.
