What is C stack?
A stack is a linear data structure, collection of items of the same type. Stack follows the Last In First Out (LIFO) fashion wherein the last element entered is the first one to be popped out. In stacks, the insertion and deletion of elements happen only at one endpoint of it.

How does a stack work in C programming?
Stack in C Programming A stack is a linear data structure, collection of items of the same type. Stack follows the Last In First Out (LIFO) fashion wherein the last element entered is the first one to be popped out. In stacks, the insertion and deletion of elements happen only at one endpoint of it.
Why does C-stack smashing detect Stack Overflow?
When I disabled the stack smashing protector no errors were detected, which should have happened when I used “./a.out wepassssssssssssssssss” So to answer your question above, the message “** stack smashing detected : xxx” was displayed because your stack smashing protector was active and found that there is stack overflow in your program.
What happens if a guard check fails in C stack smashing?
If a guard check fails, an error message is printed and the program exits. Only variables that are actually allocated on the stack are considered, optimized away variables or variables allocated in registers don’t count. Like -fstack-protector except that all functions are protected. Now we look at the disassembly:
What kind of data structure is a stack?
A stack is a linear Last-In-Last-Out (LIFO) data structure which means that the last element added to the stack will be the first one to be removed. Therefore, once a new element is added to the stack, all elements that were added after it has to be removed before the new element can be removed.
