= Meaning in C

In C, = is called a composite assignment operator, which adds the value of a variable or expression to another value and stores its result in that variable.

grammar

 <code class="c">variable = expression;</code>

in:

• variable is the variable to be modified.
• Expression is the value to be added.

How it works

The = operator is equivalent to the following code:

 <code class="c">variable = variable expression;</code>

It adds the current value of the variable to another value and then stores its result back into the variable.

Example

The following code increases the value of the variable x by 5:

 <code class="c">x = 5;</code>

Equivalent to:

 <code class="c">x = x 5;</code>

After executing the above code, the value of x will become its current value plus 5.

Notice:

• The = operator can only be used for numeric types (such as int, float, double).
• It cannot be used for strings or other non-numeric types.
