有没有办法将字节数组转换为C++中的数字？

#include <iostream>

unsigned char byteArray[] = {0x12, 0x34, 0x56, 0x78}; // 字节数组
unsigned int number = 0;

for (int i = 0; i < sizeof(byteArray); i++) {
    number = (number << 8) | byteArray[i];
}

std::cout << "转换后的数字：" << number << std::endl;

#include <iostream>
#include <cstring>

unsigned char byteArray[] = {0x12, 0x34, 0x56, 0x78}; // 字节数组
unsigned int number = 0;

std::memcpy(&number, byteArray, sizeof(number));

std::cout << "转换后的数字：" << number << std::endl;
