求大神，字符串转成其他类型怎么转
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
char szNum[10] = "123456789";
cout << *(short*)(szNum + 4) << "," << *(short*)(szNum) << endl;
int n = *(short*)(szNum + 4) - *(short*)(szNum);//1028
cout << n << endl;
return 0;
}
我想问下
cout << *(short*)(szNum + 4) << "," << *(short*)(szNum) << endl;
这两个值怎么计算
[解决办法]“*(short*)(szNum + 4)”
- szNum的类型是char *指针
- (szNum + 4)指向的是'5'的地址
- (short*)(szNum + 4)转换为short *类型指针，指向'5'首地址的两个连续字节空间
- *(short*)(szNum + 4)为'56'的值，'5'=0x35，'6'=0x36，因此它的值是0x3635=13877.
“*(short*)(szNum)”
- 同理，*(short*)(szNum)=0x3231=12849.
