![]() ![]() ![]() One way you can accomplish this is through conditional statements. Suppose you are trying to compare if the sum of two numbers is equal to the third number in C++. ![]() – Example One: Triggering Expression Must Be a Modifiable Lvalue in C++ However, if you accidentally try to assign something that is not a left operand an assignment operator (=) instead of a comparison operator (=), you will get this error. Therefore, whatever is on the left should denote something that has an allocation in memory and lets you modify it. It means you are attempting to give the value on the right a place in the memory whose name is on the left. The “l” in the “lvalue” stands for something on the left side of the (=) operator. You will get this error message as a result of an expression not producing an lvalue (value on the left side of an assignment).
