#include<bits/stdc++.h> using namespace std; int main() { int a[5]={}; float ans=0; int max=0; int min=1000; for(int i=0;i<4;i++) { cin>>a[i]; ans+=a[i]; if(a[i]>max) { max=a[i]; } if(a[i]<min) { min=a[i]; } } ans-=max; ans-=min; ans/=2; printf("%.2f",ans); }

一定要把输入的类型改成double

#include <bits/stdc++.h> using namespace std; int main() { int sum=0,a,b,c,d,max=0,min=0; double jun=0; cin>>a>>b>>c>>d; if(a>=b&&a>=c&&a>=d) { max=a; } else if(b>=a&&b>=c&&b>=d) { max=b; } else if(c>=a&&c>=b&&c>=d) { max=c; } else if(d>=a&&d>=b&&d>=c) { max=d; } }

#include <bits/stdc++.h> using namespace std; int a,b,c,d; int main() { cin>>a>>b>>c>>d; sum = a+b+c+d; int maxx,minn; maxx=max(max(max(a,b),c),d); minn=min(min(min(a,b),c),d); printf("%.2f",(sum-minn-maxx)/(2.00)); return 0; }

#include<iostream> #include<cstdio> #include<cmath>//这些我也不知道哪些要 using namespace std; int main(){ int a,b,c,d,sum; cin>>a>>b>>c>>d; sum=a+b+c+d;//计算得分和 sum-=max(max(a,b),max(c,d));//减去最高分 sum-=min(min(a,b),min(c,d));//减去最低分 printf("%.2f",sum*1.0/2);//剩余两得分求平均 }

9行搞定

#include<iostream> using namespace std; int main() { float a,b,c,d,q,w; cin>>a>>b>>c>>d; q=a; w=a; if(b>q) { q=b; } if(b<w) { w=b; } if(c>q) { q=c; } if(c<w) { w=c; } if(d>q) { q=d; } if(d<w) { w=d; } printf("%.2f",(a+b+c+d-q-w)/2); return 0; }
