Why does a recursive descent parser, processing code with deeply nested control structures in a compiler, experience stack overflow more readily than an iterative parser?

💡 Explanation

A recursive descent parser relies on function calls to handle nested structures, leading to stack growth. Because deeply nested structures trigger unbounded recursion that repeatedly adds frames to the call stack, a stack overflow occurs; therefore, the recursive descent parser is more susceptible to stack overflow, rather than techniques like tail-call optimization preventing stack growth.
