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). Both function results and constants are not assignable ( rvalue s), so they are rvalue s. so the order doesn't matter and if you forget to use == you will get ...

Particularly it is left side value of an assignment operator. rvalue means right side value. Particularly it is right side value or expression of an assignment operator. Example: a = b + 5; In above example a is lvalue and b + 5 is rvalue. In C language lvalue appears mainly at four cases as mentioned below: Left of assignment operator. Left of ...

The name lvalue comes originally from the assignment expression E1 = E2, in which the left operand E1 is required to be a (modifiable) lvalue. It is perhaps better considered as representing an object "locator value". What is sometimes called rvalue is in this International Standard described as the "value of an expression".
lvalue required as left operand of assignment error when using C++
Put simply, an lvalue is something that can appear on the left-hand side of an assignment, typically a variable or array element. So if you define int *p, then p is an lvalue. p+1, which is a valid expression, is not an lvalue. If you're trying to add 1 to p, the correct syntax is: p = p + 1; answered Oct 27, 2015 at 18:02.
Understanding The Error: Lvalue Required As Left Operand Of Assignment
Examples and Illustrations of the Error: lvalue required as left operand of assignment Assigning a value to a constant. When programming, it is important to understand the difference between variables and constants. A variable is a storage location that can hold a value, while a constant is a value that cannot be changed once it is assigned.

lvalue and rvalue in C language
R-value: r-value" refers to data value that is stored at some address in memory. A r-value is an expression, that can't have a value assigned to it, which means r-value can appear on right but not on left hand side of an assignment operator (=). C. // declare 'a', 'b' an object of type 'int'. int a = 1, b; a + 1 = b; // Error, left ...
Understanding and Resolving the 'lvalue Required: Left Operand
To resolve the "lvalue required as left operand of assignment" error, the programmer must ensure that the left operand of the assignment operator is an lvalue. Here are some examples of how to fix the code that we saw earlier:
Understanding lvalues and rvalues in C and C++
A simple definition. This section presents an intentionally simplified definition of lvalues and rvalues.The rest of the article will elaborate on this definition. An lvalue (locator value) represents an object that occupies some identifiable location in memory (i.e. has an address).. rvalues are defined by exclusion, by saying that every expression is either an lvalue or an rvalue.
Else without IF and L-Value Required Error in C
The if-else statement in C is a flow control statement used for decision-making in the C program. It is one of the core concepts of C programming. It is an extension of the if in C that includes an else block along with the already existing if block.

Assignment Operator in C Language
Syntax Of Assignment Operator: 1. L-Value = R-Value. The assignment operator is for used assigning values. In general assignment operator assigns the value of the right-hand ( R-Value) side operand to the Left-hand (L-Value) side Operand. The assignment operator is a binary operator so it must need two operands.

Check all your 'if' statements for equality. You are incorrectly using the assignment operator '=' instead of the equality operator '=='.
Lvalue Required as Left Operand of Assignment: Effective Solutions
