C Code, Can U Solve This? Another interesting problem

How do I manipulate and change the value of i?

Technically you aren't changing the value of i -- you're defining a new i (it's at a new memory address). To answer your puzzle, you can change the value of i using an ASM injection attack using a noop sled to compensate for the variance in memory allocation addresses.

8bit, you can't do that (can have only 1 return 0;)

The reason why he can't do it is because the return type is void, but if it was int like this:

int fun(void)
{

}

then he can do it.

Oh yea?void fun(void){randomlineofetext(3249830325) }the program won't print anything at all xD

void fun(void){  int * ptr =&i;  *ptr=50;}

Beat that.

This code wont work as the variable i is undeclared for fun()....it would have worked if "i" had been a global variable

There is another way if you wish to use pointers...

void fun(int *ptr){  *ptr=50;}int main(){int i = 20;fun(&i);printf("i = %d\n", i);return 0;}

the output will be 50

#include <stdio.h>void fun(void){#define fun() i=10}int main(){int i = 20;fun();printf("i = %d\n", i);return 0;}

I think that this won't work :
(i guess) we can't put preprocessor directives on a function
If we can , it won't work also , because the compiler or the processor had completed the line :

fun();

so he won't replace it .

if the preprocessor works in functions i guess this will be the answer

void fun(void){#define printf("i = %d\n", i) i=0}int main(){int i = 20;fun();printf("i = %d\n", i);return 0;}

What do you think ???

printf is a standard function in C. You can't modify it.Try doing the same thing in c++.
