Understanding and Resolving "Expression Must Be a Modifiable L-value" in C
This article provides an in-depth analysis of the common C language error "expression must be a modifiable l-value," focusing on the fundamental differences between character arrays and character pointers in assignment operations. By examining the constant pointer nature of array names versus the flexibility of pointer variables, it explains why direct string assignment to character arrays causes compilation errors. Two practical solutions are presented: using character pointers with constant strings, or safely copying string content via the strcpy function. Each approach includes complete code examples and memory operation diagrams, helping readers understand the underlying mechanisms of string handling in C.
