What to Do When You Get a 'Stack Overflow' Error in C++

A 'Stack Overflow' error in C++ occurs when the program exceeds the call stack’s capacity, often due to excessively deep recursion or the allocation of large local variables.

The most common cause of a stack overflow is infinite recursion, where a function keeps calling itself without a proper base case.

To fix this, ensure that recursive functions have a well-defined base case and that the recursion depth is kept within reasonable limits.

If using large data structures in local variables, consider allocating them on the heap using new or malloc() to prevent excessive stack memory usage.

You can also try to reduce the number of recursive calls or optimize the algorithm to reduce the stack depth.

Using an iterative approach instead of recursion may be beneficial for some problems.

Tools like gdb or valgrind can help track down the exact line where the stack overflow occurs, allowing for easier debugging and fixes.
