(1)程式碼：readbosh.cpp
#include <fstream>
#include <iostream>
#include <regex>
using namespace std;
int main(){
FILE *infile;
infile = fopen("ansiBoshiamy.cin", "r");
string input;
printf("請輸入要查的字串：");
getline(cin, input);
string s1= input + " (.*)(\\n)";
regex reg(s1,regex_constants::icase);
char ln[100];
int c=0;
while (!feof(infile)) {
fgets (ln , 100 , infile);
if( regex_match(ln, reg) ){
cout << " 找到匹配" <<" c=" << c++ << ":"<< ln << endl;
}
}
fclose(infile);
return 0;
}
(2)執行結果：
請輸入要查的字串：aaa
找到匹配 c=0:aaa 鑫
找到匹配 c=1:aaa 龘
找到匹配 c=2:aaa 鑆
