Reinterpret cast not showing correctly

[binary2]

I have the following:

ctx->state0 is a 200 byte array

I'm using reinterpret cast to convert the array to 32 bit values and to 64 bit values instead of 8 bits

uint64_t* h0 = reinterpret_cast<uint64_t*>(ctx->state0);
uint32_t* h00 = reinterpret_cast<uint32_t*>(ctx->state0);

cout << h0[1] << endl;
cout << h00[3]<< endl;

for h0[0] the values in h00[0] and h00[1] corespond
for h0[1] the values in h00[2] and h00[3] don't corespond

h0[1] = 1011010100110110101011001111011100011111101011010001011010000
h00[2] = 11100111100110000101110000100111
h00[3] = 11100010100001000101100000110100

In what system did you test this?
Could you post the complete code example?

As Victor requests, would you post your code example.

However, consider

#include <cstdint>
#include <iostream>
using namespace std;

int main()
{
	uint64_t i64 = 0b1011010100110110101011001111011100011111101011010001011010000;

	uint32_t *p32 = reinterpret_cast<uint32_t*>(&i64);

	uint32_t p0 = p32[0];
	uint32_t p1 = p32[1];

	cout << hex << "i64 " << i64 << "  i32[0] " << p0 << "  i32[1] " << p1 << endl;
}

which displays

i64 16a6d59ee3f5a2d0  i32[0] e3f5a2d0  i32[1] 16a6d59e

Reinterpret cast not showing correctly

Why do you think it is a "reinterpret cast" problem?
It seems to more likely be a big/little endian problem.
