Application Security Testing: An Integral Part of DevOps

Compilation Errors

What is an "lvalue"? How does it relate to "rvalue"?

An lvalue is simply a value on the left side of an expression, and an rvalue is a value on the right side of an expression.

i = 5;
For example, here i is the lvalue and 5 is the rvalue.

The compiler sometimes uses these terms because the rules often differ for these two values. For example, while the statement above is valid, this one is not.

5 = i;
