C++实现读入二进制数并转换为十进制输出
5星 · 资源好评率100%
在C++中,cout默认是以十进制形式输出数字。如果要输出三十二进制数,可以使用setiosflags(ios_base::hex)来设置输出为十六进制,然后将数字转换为unsigned long类型。以下是一个示例代码:
```cpp
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int num = 32;
cout << setiosflags(ios_base::hex) << num << endl;
return 0;
}
```
这段代码将输出数字32的十六进制表示,即20。
