而且这个if(m[0]='a'&&!m[1])如果放在for循环之前，为什么只输出1

include<iostream>

include<string>

include<algorithm>

using namespace std;

int a[6],j=0;

int main(){

string m;
string str[26]={"one","two","three","four","five","six","seven","eight","nine","ten","eleven","twelve","thirteen","fourteen","fifteen","sixteen","seventeen","eighteen","nineteen","twenty","both","another", "first", "second","third"};
while(1){
    cin>>m; 
    if(m[0]=='.') break;
    if(m[0]<=97) m[0]+=32;
    for(int i=0;i<26;i++){
        if(m==str[i]){  
            if(i==22) {
                a[j]=1;
                j++;
                cout<<a[j]<<endl;
            }
            else if(i==20||i==23) {
                a[j]=4;
                j++;
            }
            else if(i==21||i==24) {
                a[j]=9;
                j++;
            }
            else{
                a[j]=(i+1)*(i+1)%100;
                j++;
            }
        }
    }
    if(m[0]='a'&&!m[1]){
            a[j]=1;
            j++;    
        }
}
sort(a,a+j);
cout<<a[0];
for(int i=1;i<j;i++){
    if(a[i]<10) cout<<0<<a[i];
    else cout<<a[i];
}

}
