Question

Here is the thing, 1024 = 0x400, and I assume its binary representation (little endian) is \\x00\\x4\\x00\\x00. And I try to do something like this,

int main()
{
    const char *str = "\\x00\\x4\\x00\\x00";
    const int *p = (const int *)str;
    printf("%d\n", *p);
}

But why the above code can’t give me 1024?

Answer 1

Because you escaped \. Unescape them:

const char *str = "\x00\x4\x00\x00";
