unsigned c++

引用:#include<reg51.h> #define uint unsigned int #define uchar unsigned char。 引用:令人气愤的AC #include <iostream> using namespace std; int main() { unsigned long long n,ans; cin>>n; ans=n * (n-1) / 2 * (n-2) / 3 * (n-3) / 4; cout<<ans<<endl; return 0; } 。 引用:令人满意的AC #include <iostream> using namespace std; int main() { long long n,ans; cin>>n; if(n%2) ans=n*((n-1)*(n-2)*(n-3)/24); else ans=n*(n-1)*(n-2)/24*(n-3); cout<<ans<<endl; return 0; } 。 问题:请告诉我，unsigned c的含义是什么？
根据提供的引用内容，unsigned c是预处理指令#define uchar unsigned char的定义中的一部分。在这个定义中，uchar被定义为unsigned char的别名。因此，unsigned c可以被理解为unsigned char的另一种写法。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
