水题一个,直接用getchar然后遇到空格判断一下就成
1 #include <iostream> 2 #include <cstdio> 3 #include <cstring> 4 using namespace std; 5 int n,Max=0,p=0; 6 char c; 7 string s; 8 int main() { 9 scanf("%d",&n); 10 for(int i=0;i<=n;i++){ 11 c=getchar(); 12 if(c==' '){ 13 Max=max(Max,p); 14 p=0; 15 }else{ 16 if(c>='A'&&c<='Z'){ 17 p++; 18 // cout<<c<<p<<endl; 19 } 20 } 21 } 22 Max=max(Max,p); 23 printf("%d ",Max); 24 return 0; 25 }
