题目如下:

 

 思路:

1.输入完成后会按enter 要记得\n也会被计入数字喔!

代码:

#include<cstdio>
#include<cstring>>
#include<iostream>
using namespace std;
int main(){
    string ss;
    getline(cin,ss);
    int sum=0;
    int len=ss.size();
    int a[26]={1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,4,1,2,3,1,2,3,4};
    for(int i=0;i<len;i++){
        if(ss[i]>='a'&&ss[i]<='z')
        sum+=a[ss[i]-'a'];        
        else if(ss[i]==' ')
        sum+=1;
    }
    cout<<sum;
    return 0;
}
//i have a dream
//3+1+2+1+3+2+1+1+1+1+3+2+1+1= 23
