简便做法

#include <iostream>
#include <string>
using namespace std;
int main(){
    int key[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  
    };
    string str;
    getline(cin,str);
    int t=0;
    for (char c:str){
        if (c==' '){
            t+=1;
        }
        else{
            t+=key[c-'a'];
        }
    }
    cout<<t<<endl;
    return 0;
