普通打发Be like:

#include<iostream>
#include<sstream>
using namespace std;
string s;
stringstream ss;
int a,b,ans=0,p,i,c,j;
int main(){
    scanf("%d %d",&a,&b);
    p=a;
    while(p<=b){
        i=2;
        while(p%i!=0&&i<p)i++;
        if(i==p){
            ss<<p;
            ss>>s;
            c=(s[1]-'0')*10+s[0]-'0';
            j=2;
            while(c%j!=0)j++;
            if(c==j)printf("%d\n",p);
            ss.clear();
            s.clear();
        }
        p++;
    }
}

打表Be like:

#include<stdio.h>
int v[9]={11,13,17,31,37,71,73,79,97},a,b;
int main(){
    scanf("%d %d",&a,&b);
    for(int i=0;i<9;i++)
        if(v[i]>=a&&v[i]<=b)
            printf("%d\n",v[i]);  
}
