Question

If your program produces an error message that says stack overflow, what is a likely source of the error?

Short answer

Answer: A stack overflow error occurs when a program consumes more stack memory than it is allowed, typically due to an excessive number of function calls being stored in the call stack. The two most common sources of this error are 1) improperly implemented recursive functions with a missing or incorrect base case, and 2) excessive memory allocation within a function call.

Step-by-step solution

Understanding Stack Overflow Error

A stack overflow error occurs when a program consumes more stack memory than it is allowed. This often happens when a program calls too many functions recursively, resulting in an excessive number of function calls being stored in the call stack. When the call stack becomes too large for the allocated memory, a stack overflow error is thrown.

Identifying the Likely Source of the Error

The most common source of a stack overflow error is using a recursion technique improperly or without a proper base case. When a function is called recursively, it keeps calling itself until it reaches the base case. If the base case is not defined or implemented correctly, the function may not terminate and keep calling itself indefinitely, ultimately leading to a stack overflow error. Another possibility could be the dynamic allocation of large data structures within a function call. If a function allocates a large amount of memory on the stack, it can exceed the stack size limit and cause a stack overflow error. In summary, the likely source of a stack overflow error is: 1. Improperly implemented recursive function (missing or incorrect base case) 2. Excessive memory allocation within a function call
