문자열 찾기(C++)

80개 이하의 문자로 이루어진 문자열 a과 또다른 문자열 b를 입력받아 a에 b의 문자열이 포함되어있으면 그 위치를 출력하고 그렇지 않으면 -1을 출력한다.

 #include <iostream>
#include <windows.h>

using namespace std;
int main(){
   
    string a,b;
    int i,j;
    bool accord,find;
   
    getline(cin,a);
    getline(cin,b);
   
   
    find = false;
   
    for(i=0;i<=a.length()-b.length();i++){
                                          accord = true;
                                         
                                          for(j=0;j<b.length();j++){
                                                                    if(a[i+j]!=b[j]){
                                                                                     accord=false;
                                                                                     break;
                                                                    }
                                          }
                                          if(accord){
                                                     cout<<i+1<<endl;
                                                     accord=true;
                                                     find = true;
                                          }
    }
   
    if(!find)cout<<-1;
   
    system("PAUSE");
    return 0;
}
