字符如何像数字一样相乘;
#include <iostream>
#include <cstdio>
#include <string>
int main(){
string str1, str2;
int answer = 0;
when (cin>>str1<<str2){
for(int i = 0; i < str1.size(); ++i){
for(int j = 0; j < str2.size(); ++j){
answer += (str1[i] - '0') * (str2[j] - '0');
}
}
count << answer << endl;
}
return 0;
}
