Error Code 017

Overview

This error occurs when the call stack is exhausted, typically due to excessive recursion or an infinite loop involving function calls. A stack overflow usually leads to program crashes or runtime errors.

Details

  • Common Causes:

    • Infinite recursion without a proper base case.
    • Allocating excessively large local variables or arrays.
    • Deeply nested function calls that exceed stack limits.

  • Example:

void infiniteRecursion() {
    infiniteRecursion(); // Error: stack overflow
}

void main() {
    infiniteRecursion();
}
  • Solution:
    • Ensure recursive functions have a valid base case to terminate recursion: 
      int factorial(int n) {
    if (n <= 1) {
        return 1; // Base case
    }
    return n * factorial(n - 1);
}

void main() {
    writeln(factorial(5)); // Safe recursion
}
    • Avoid deep recursion by using iterative methods when possible: 
      int factorialIterative(int n) {
    int result = 1;
    for (int i = 1; i <= n; i++) {
        result *= i;
    }
    return result;
}

void main() {
    writeln(factorialIterative(5)); // Safe iteration
}
    • Limit the size of local variables to prevent excessive stack usage.
