 The `char buffer[20];` is a really bad idea. The rest will be demonstrated in the course.
+
+You can compile this code or use the already-compiled binary [here](https://github.com/The-Art-of-Hacking/h4cker/raw/master/buffer_overflow_example/vuln_program).
+
+For 32 bit systems you can use [gcc](https://www.gnu.org/software/gcc/) as shown below:
+```
+gcc vuln.c -o vuln -fno-stack-protector
+```
+For 64 bit systems
+
+```
+gcc vuln.c -o vuln -fno-stack-protector -m32
+```
+`-fno-stack-protector` disabled the stack protection. Smashing the stack is now allowed. `-m32` made sure that the compiled binary is 32 bit. You may need to install some additional libraries to compile 32 bit binaries on 64 bit machines.
