#include<bits/stdc++.h>
using namespace std;

最NB的词组缩写:

这是第3题

对不起，发错了

#include<bits/stdc++.h>
using namespace std;
char xhd[100000];
int main(){
    int sum = 0;
    gets(xhd);
    for(int i = 0;i < 100000;i++){
        if(xhd[i] >= 'A' && xhd[i] <= 'Z'){
            sum++;
        }
    }
    cout << sum << endl;
}
