c program stack smashing detected

How to solve stack smashing detected in C?
To correct the problem, verify that all of your buffers are large enough to contain their intended data.
Instead of using unsafe methods like gets(), use secure ones like fgets().
To avoid buffer overflows, validate user input.
Stack protection can be enabled with compiler settings such as -fstack-protector._{26 déc. 2023}
What causes 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.
What does it mean by stack smashing detected?
This error is a defensive mechanism used to prevent stack-based buffer overflows.
The compiler uses a random sequence of bits called canary to check for buffer overflow and based on that, produces the stack smash detected error in C.
This is a runtime error and leads to the termination of the running program.
We can disable it by using the -fno-stack-protector option of gcc.
There are other options of gcc for stack protection.
For example, the -fstack-protector-strong option is like the -fstack-protector option, but it also protects against buffer overflows in functions having local array definitions.

Usually, the compiler generates the stack smashing detected error in response to its defense mechanism against buffer overflows. A buffer overflow occurs when the user input exceeds the buffer capacity. The following C code can cause the buffer to overflow if the user enters more than ten characters.
