2840.cpp

这些是我到目前在PKU上做出的题目

#include <iostream.h>
#include <string.h>
int main()
{char a[6];
 long n,i,h,m;
 unsigned j;
 cin>>n;
 for (i=1;i<=n;i++)
 {cin>>a;
  h=0;m=0;j=0;
  while (a[j]!=':') {h=h*10+a[j]-48;j=j+1;}
  j=j+1;
  while (j<=strlen(a)-1) {m=m*10+a[j]-48;j=j+1;}
  if (m!=0) cout<<"0\n"; else cout<<(h+11)%24+1<<"\n";}
return 0;
}
