Solve error: lvalue required as left operand of assignment
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 member access (dot) operator (for structure and unions). Right of address-of operator (except for register and bit field lvalue). As operand to pre/post increment or decrement for integer ...
Lvalue Required as Left Operand of Assignment: What It Means and How to
Why is an lvalue required as the left operand of an assignment? The left operand of an assignment operator must be a modifiable lvalue. This is because the assignment operator assigns the value of the right operand to the lvalue on the left. If the lvalue is not modifiable, then the assignment operator will not be able to change its value.

Assignment Expressions (GNU C Language Manual)
An assignment in C is an expression because it has a value; we call it an assignment expression. A simple assignment looks like. lvalue = value-to-store. We say it assigns the value of the expression value-to-store to the location lvalue, or that it stores value-to-store there. You can think of the "l" in "lvalue" as standing for ...
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: int x = 5; x = 10; // Fix: x is an lvalue int y = 0; y = 5; // Fix: y is an lvalue
error: lvalue required as left operand of assignment-C
Also I would like to ask if this is faster than the traditional way to print the list with printf and then assigning the pointer to the next node. error: lvalue required as left operand of assignment-C
error: lvalue required as left operand o
The left side of an assignment operator must be an addressable expression. Addressable expressions include the following: numeric or pointer variables
[SOLVED] lvalue required as left operand of assignment
lvalue required as left operand of assignment this is on the line. Code: SET_BIT(bar->act,bit3); I am 100% certain that this used to compile fine in the past (10 years ago :-o); Why is it saying that bar->act is not a valid lvalue while both bar->act and the bit are cast to (long long)?

lvalue required as left operand of assignment
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 ...

Arduino code compile error: "lvalue required as left operand of assignment"
The problem here is you are trying to assign to a temporary / rvalue. Assignment in C requires an lvalue. I'm guessing the signature of your buttonPushed function is essentially the following. int buttonPushed(int pin);
