a.out returns something else everytime.

PHP Code


<?php 
int main(int argc, char *argv[])
{
    std::cout << (int)argv[2] + (int)argv[3] << std::endl;
   
}

You are just casting random pointers to int. Nothing special and not worth making a thread about it.

using namespace std;

^ use this more often

using namespace std;

Dont use that more often. Its a bad practice. Its fine for smaller projects but keep in mind that the std namespace has tons of identifiers, many of which are very common ones (think list, sort, string, iterator, etc.) which are very likely to appear in other code, too.

The OP's code looks like something from a school assignment, in that case std is fine to use 99% of the time.

I tried this just now.

PHP Code


<?php 
#include <stdio.h>
#include <stdlib.h>

int main() {
    
    short i = 10;
    
    while (i) {
        
        void *ptr = (int *)malloc(1);
    
        printf("%p:%d\n", ptr, ptr);
        
        free (ptr);
        
        --i;
    }
    
    return 0;
} 


Output:

Ahh yes, there is a VIRTUAL MEMORY !!

That's just ASLR in action.

No it's just experiments. NO School assignment.

Anyway, I just wanted to know why that was happening. Thanks alot people.

Still, better to avoid bad practice for future sake than ignore what might be ahead and do it anyway. Maybe that philosophy is a bit much for simple stuff such as a statement for namespace usage, but it can tie in with anything and does with everything lol.

It actually makes me feel a bit better because I can see I'm not the only one specifying separate namespaces even on small tinkering projects like this.
