Please see attached source code written in C++. Can you make the code print Hello World! by providing it with an input string? You are NOT allowed to modify the source code. Compile the code with g++. Submit your input string and the screenshot proving that the code prints Hello World!.

Hint: You may use hex editors like Notepad++ to generate the input string. Alternatively, you can write a program to generate the string.

Update: Starting from Microsoft Vista, Windows OS also uses ASLR. There are many resources online. I havent tested them. But you can try some of the methods online to finish the homework.

Tell me how to do it.

bof.cpp

#include  #include  using namespace std; char *p; void f1() { char str[8]; p = str; cout << "Please enter a string:"; while (!cin.eof()) { cin.get(*p); p++; } cout << "The string you entered is:" << str << endl; } void f2() { cout << "Hello World! "; } int main() { cout << sizeof(char*) << endl; cout << (void*) f2 << endl; f1(); return 0; }
