How can I use uint8_t which represent 16 bit integers

Question

How can I use uint8_t which represent 16 bit integers

as uint16_t pointer?
each two bytes in the uint8_t represent 16 bit integer
the first number here should be 1 but it outcome as 256

#include <stdint.h>
#include <stdio.h>

int main() {
uint8_t byteArray[] = {0x00, 0x01, 0x00, 0x02, 0x00, 0x03}; // Example data
uint16_t* uint16Array = (uint16_t*)byteArray;

for (int i = 0; i < 3; i++) {
printf("uint16Array[%d] = %u\n", i, uint16Array[i]);
}

return 0;
}

Ideally, it'll be better to stote numbers in u16 then scan it as u8

Hmm right, this answer also says that the implementation of cout isn't specified https://stackoverflow.com/questions/62852221/does-cout-cin-internally-call-printf-scanf-like-new-calls-malloc
