arrays - Number input from txt file. Weird glitch C++ -


this homework , i've developed of on own already. keep getting weird glitch. in input file below supposed take name , numbers , put them 6 different variables. name string numbers arrays , last 2 numbers ints.

when run program , want grab tenth number of strings presents me next 1 on eg. want 94 15 in alice's grades.

here's file , here code please help.

#include <iostream> #include<string> #include <fstream> #include <sstream>  using namespace std;  //all of students info stored here struct student {     string name;     int asgn[9];     int quiz[9];     int lab[9];     int midterm;     int final;  }; student s[22];        int main(){      string str;     ifstream in;       in.open("c:/cs161grades.txt");      (int = 0; < 22; i++){         getline(in, str);         stringstream ss(str);         ss >> s[i].name >> s[i].asgn[0] >> s[i].asgn[1] >> s[i].asgn[2] >> s[i].asgn[3] >> s[i].asgn[4] >> s[i].asgn[5] >> s[i].asgn[6] >> s[i].asgn[7] >> s[i].asgn[8] >> s[i].asgn[9]             >> s[i].quiz[0] >> s[i].quiz[1] >> s[i].quiz[2] >> s[i].quiz[3] >> s[i].quiz[4] >> s[i].quiz[5] >> s[i].quiz[6] >> s[i].quiz[7] >> s[i].quiz[8] >> s[i].quiz[9]             >> s[i].lab[0] >> s[i].lab[1] >> s[i].lab[2] >> s[i].lab[3] >> s[i].lab[4] >> s[i].lab[5] >> s[i].lab[6] >> s[i].lab[7] >> s[i].lab[8] >> s[i].lab[9]             >> s[i].midterm             >> s[i].final;          cout << s[2].name << s[2].lab[9] << endl;     }        //pause , stop     getchar();     getchar();     return 0; } 

the file formatted such twenty students

  name     assignments                      quizzes                          labs                              midt  final      alice    71 97 64 30 99 54  8 88 92 94    15 55 91 37 71  1  5 52 37 46     6 19 17 68  7 97 36 31 33 10     72    46 

here:

int asgn[9]; 

that's room enough nine numbers (asgn[0] through asgn[8]), you're trying store ten in it. assignment asgn[9] writes past end of array, undefined behavior.
