Error lvalue required as left operand of assignment. 原因： 计算值为 ！= 变量为= 赋值语句的左边应该是变量，不能是表达式。而实际上，这里是一个比较表达式，所以要把赋值号（＝）改用关系运算. Dec 19, 2018  Published on Dec 19, 2018 How to fix c/c compiler error: lvalue required as left operand of assignment? The operator '=' must have an l-value as its left operand. Dec 15, 2011  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.

this is what compiler shows
tree.cpp: In member function ‘void redblacktree<T>::insert(T) [with T = int]’:
tree.cpp:187:12: instantiated from here
tree.cpp:103:9: error: lvalue required as left operand of assignment
tree.cpp:140:9: error: lvalue required as left operand of assignment

if u don't want 2 go thru' d code then kindly just tell when such compilation error occur.

Another line that raises red flags is this one:

Function As Left Operand

Did you intend to use assignment?
