Stack Smashing in C++

Stack smashing in C++ is a form of buffer overflow. It happens when a program writes more data to the stack than its available memory allocation, causing adjacent memory locations to be overwritten.

Example of stack smashing

Here's an example of an array containing the five numbers:

int A[5] = {1,2,3,4,5};
A[6] = 2;

If we attempt to update the 6th index, the message stack smashing detected will be displayed on the console, and the program will end abruptly.
