本人一个智障，string怎么用都不记得了....

#include <iostream>
#include <cstdio>
#include <cstring>
using namespace std;

string s[15];

//按键没有坏之前
s[1] = "   ";  s[2] = "abc"; s[3] = "def";
s[4] = "ghi";  s[5] = "jkl"; s[6] = "mno";
s[7] = "pqrs"; s[8] = "tuv"; s[9] = "wxyz";


string c[15]; //坏了之后的按键

int n[15]; //一开始输入的数字

string str; //要输入的字符串

int main () {
    for (int i = 1; i <= 9; ++i)
        cin >> n[i];
    
    for (int i = 1; i <= 9; ++i) 
        c[i] = s[ n[i] ]; //键盘坏了，改变
    

    cin >> str;
    int last_e; //方便特判输出'#'
    for (int k = 0; k < str.length(); ++k) {
        char now = str[k];

        int e, l; //e代表是哪个按键，l是输出几次
        for (int i = 1; i <= 9; ++i) {
            for (int j = 0; j < c[i].length(); ++i) {
                if (c[i][j] == now) {
                    e = i; l = j + 1;
                    break;
                }
            } 
        }

        if (e == last_e) {
            cout << '#';
        }

        for (int i = 1; i <= l; ++i) 
            cout << e;

        last_e = e;
    }

    return 0;
}

您看前面的那块赋值，就是s[1] = *** ,s[2] = *** 那里报错了，蒟蒻没看懂报错信息？

大佬指点一下哪里错了啊
