Pointer reference and dereference
- by ZhekakehZ
I have the following code:
#include <iostream>
char ch[] = "abcd";
int main() {
std::cout << (long)(int*)(ch+0) << ' '
<< (long)(int*)(ch+1) << ' '
<< (long)(int*)(ch+2) << ' '
<< (long)(int*)(ch+3) << std::endl;
std::cout << *(int*)(ch+0) << ' '
<< *(int*)(ch+1) << ' '
<< *(int*)(ch+2) << ' '
<< *(int*)(ch+3) << std::endl;
std::cout << int('abcd') << ' '
<< int('bcd') << ' '
<< int('cd') << ' '
<< int('d') << std::endl;
}
My question is why the pointer of 'd' is 100 ? I think it should be:
int('d') << 24; //plus some trash on stack after ch
And the question is why the second and the third line of the stdout are different ?
6295640 6295641 6295642 6295643
1684234849 6579042 25699 100
1633837924 6447972 25444 100
Thanks.
