你们的代码都好长啊

#include <cstdio>
#include <iostream>
#include <cstring>
using namespace std;
double p[2][8]={4.5,4,3.5,3,2.5,2,1,0,5,4.5,4,3.5,2.5,2,1,0};
string c[8]={"A+","A","B+","B","C+","C","D","F"};
int n,m;
int main()
{
    cin>>n>>m;
    if(n>100.0) printf("Error");
    else if(n>=95)cout<<c[0]<<endl<<p[m][0];
    else if(n>=90)cout<<c[1]<<endl<<p[m][1];
    else if(n>=85)cout<<c[2]<<endl<<p[m][2];
    else if(n>=80)cout<<c[3]<<endl<<p[m][3];
    else if(n>=75)cout<<c[4]<<endl<<p[m][4];
    else if(n>=70)cout<<c[5]<<endl<<p[m][5];
    else if(n>=60)cout<<c[6]<<endl<<p[m][6];
    else if(n>=0)cout<<c[7]<<endl<<p[m][7];
    else printf("Error");
    return 0;
}

把这道乱七八糟的分支结构尽可能的简化
（？？？）

score=float(input())
point=0
#判断是否录入错误
if score>100 or score<0 :
    print("Error")
else :
    #判断等级顺便预处理积分
    if score>=90 :
        print("A",end="")
        point=4
    elif score>=80 :
        print("B",end="")
        point=3
    elif score>=70 :
        print("C",end="")
        point=2
    elif score>=60 :
        print("D")
        point=1
    else :
        print("E")
        point=0
    #判断有没有必要加加号
    if score%10>=5 and score>=70 :
        print("+")
        point+=0.5
    else :
        print("")
        #判断是否需要积分优惠
    if int(input())==1 and point>=3 :
        point+=0.5
        #判断输出类型
    if point%1==0 :
        print(int(point))
    else :
        print(float(point))

有更简解法欢迎补充
打表就算了
