Analysis and Solutions for "initial value of reference to non-const must be an lvalue" Error in C++
This paper provides an in-depth examination of the common C++ compilation error "initial value of reference to non-const must be an lvalue". Through analysis of a specific code example, it explains the root cause: when a function parameter is declared as a non-const pointer reference, passing a temporary address expression causes compilation failure. The article presents two solutions: changing the parameter to a const pointer reference to avoid modifying the pointer itself, or creating a pointer variable as an lvalue for passing. Additionally, the paper discusses core concepts including lvalues, rvalues, references, and const qualifiers in C++, helping developers deeply understand type systems and memory management mechanisms.
