Buffer Overflow Example

This is an example of a very bad coding practices that introduces a buffer overflow. The purpose of this code is to serve as a demonstration and exercise for The Art of Hacking Series and live training

#include <stdio.h>

void secretFunction()
{
    printf("Omar's Crappy Function\n");
    printf("This is a super secret function!\n");
}

void echo()
{
    char buffer[20];

    printf("Please enter your name:\n");
    scanf("%s", buffer);
    printf("You entered: %s\n", buffer);    
}

int main()
{
    echo();

    return 0;
}

The char buffer[20]; is a really bad idea. The rest will be demonstrated in the course.
