lvalue required as left operand of assignment error when ...
When you have an assignment operator in a statement, the LHS of the operator must be something the language calls an lvalue. If the LHS of the operator does not evaluate to an lvalue , the value from the RHS cannot be assigned to the LHS.
Solve error: lvalue required as left operand of assignment
In this tutorial you will know about one of the most occurred error in C and C++ programming, i.e. lvalue required as left operand of assignment. lvalue means leftside value. Particularly it is left side value of an assignment operator.

if (strcmp("hello", "hello") == 0) ^. Because you want to check if the result of strcmp("hello", "hello") equals to 0. About the error: lvalue required as left operand of assignment. lvalue means an assignable value (variable), and in assignment the left value to the = has to be lvalue (pretty clear).
Else without IF and L-Value Required Error in C
L-value required. This error occurs when we put constants on left hand side of = operator and variables on right hand side of it. Example: C. #include <stdio.h> void main() { int a; 10 = a; } Output: prog.c: In function 'main': prog.c:6:5: error: lvalue required as left operand of assignment. 10 = a; ^
Understanding The Error: Lvalue Required As Left Operand Of ...
If we mistakenly write the assignmentstatement as “y = x = y,” we will encounter the “lvaluerequiredas leftoperandof assignment” error. This is because the assignment operator (=) requires an lvalue (a variable or memory location that can be modified) on the left side.
Demystifying C++‘s "lvalue Required as Left Operand of ...
The key phrase is "lvalue required as left operand of assignment." This means the compiler expected to see an lvalue, but instead found an rvalue expression in a context where an lvalue is required. Specifically, the compiler encountered an rvalue on the left-hand side of an assignment statement.

Learn what an lvalue is and how to fix the lvaluerequiredasleftoperandofassignment error in C++. With our step-by-step guide, you'll be able to resolve this error and get your code back on track in no time.
12.2 — Value categories (lvalues and rvalues) – Learn C++
If you’re not sure whether an expression is an lvalue or rvalue, try taking its address using operator&, which requires its operand to be an lvalue. If &(expression); compiles, expression must be an lvalue:

L-value: “l-value” refers to memory location which identifies an object. l-value may appear as either left hand or right hand side of an assignment operator (=). l-value often represents as identifier. Expressions referring to modifiable locations are called “ modifiable l-values “.

An assignment expects an lvalue as its leftoperand, and var is an lvalue, because it is an object with an identifiable memory location. On the other hand, the following are invalid:
