我嘞个雷

#include<bits/stdc++.h>
using namespace std;
int main()
{
int a,b;
freopen("aplusb.in","r",stdin);
freopen("aplusb.out","w",stdout);
cin>>a>>b;
cout<<a+b;
fclose(stdin);
fclose(stdout);
return 0;
}
这个水体有点儿水

求教程！！！

挺简单

题太水 答案供参考
#include <bits/stdc++.h>
using namespace std;
int main()
{
string s;
int i,n,st,s1=0;
freopen("csp2019pj_number.in","r",stdin);
freopen("csp2019pj_number.out","w",stdout);
getline(cin,s);
st=s.length();
for(i=0;i<=st-1;i++)
if(s[i]=='1') s1++;
if(s1==0) cout<<'0';
else cout<<s1;
fclose(stdin);
fclose(stdout);
}

#include<bits/stdc++.h>
using namespace std;
int main()
{freopen("title.in","r",stdin);
freopen("title.out","w",stdout);
char st[200];int sum;
while(scanf("%s",st)==1) sum+=strlen(st);
cout<<sum;
}

so easy

这道题太水，别写了
#include <bits/stdc++.h>
using namespace std;
int main()
{
int A,B,C,s=0;
freopen("nscore.in","r",stdin);
freopen("nscore.out","w",stdout);
cin>>A>>B>>C;
s=A*0.2+B*0.3+C*0.5;
cout<<s;
fclose(stdin);
fclose(stdout);
return 0;
}

Just so so~
