C++, I get an infinite loop when I execute this code -

i have been trying find out problem can not pinpoint it. appreciated:

#include<iostream> #include<fstream>  #define infile "input.txt"  using namespace std;   void readfromfile(int numofpeopleandsalary[6][2], int departmentid[50][6], int &counter, int &totalsalary) {     int id, depnum, salary, peoplenum;     counter = 0;      ifstream myfile;     myfile.open(infile);      if (myfile.fail())     {         cout << "did not read file, there problem" << endl;         system("pause");     }     else     {           while (!myfile.eof())         {             myfile >> id >> depnum >> salary;               numofpeopleandsalary[depnum][0] = numofpeopleandsalary[depnum][0] + 1;             numofpeopleandsalary[depnum][1] = numofpeopleandsalary[depnum][1] + salary;              peoplenum = numofpeopleandsalary[depnum][0];              departmentid[peoplenum][depnum] = id;              totalsalary = totalsalary + salary;              counter++;         }     } }  int averagefunction(int counter, int totalsalary, int numofpeopleandsalary[6][2], int departmentid[50][6], int secondaverage[6]) {     int average;      if (counter == 0)     {         average = 0;     }     else     {         average = totalsalary / counter;     }      (int = 1; < 6; i++)     {         if (numofpeopleandsalary[i][0] == 0)         {             secondaverage[i] = 0;         }         else         {             secondaverage[i] = numofpeopleandsalary[i][1] / numofpeopleandsalary[i][0];         }     }      return average; }  int main() {     int counter, average, numberofpeeps;     int numofpeopleandsalary[6][2] = {0,0,0,0,0,0,0,0,0,0,0,0};     int departmentid[50][6];     int secondaverage[6];     int totalsalary = 0;      readfromfile(numofpeopleandsalary, departmentid, counter, totalsalary);      average = averagefunction(counter, totalsalary, numofpeopleandsalary, departmentid, secondaverage);      (int = 1; < 6; i++)     {         cout << "department #: " << << " number of people: " << numofpeopleandsalary[i][0]             << " total salary: " << numofpeopleandsalary[i][1] << endl;         cout << secondaverage[i] << endl;          numberofpeeps = numofpeopleandsalary[i][0] + 1;          cout << "----------employee id's---------" << endl;         (int j = 1; j < numberofpeeps; i++)         {             cout << departmentid[j][i] << endl;         }      }      system("pause");     return 0; } 

when run should read information external file (input.txt) , make calculations. inside external file have these test cases:

23 1 66 6 3 54 213 5 54 434 4 24 324 4 32 789 2 32 4 2 24 345 3 32 568 5 12 24 1 67 789 3 54 24 5 56 56 2 43 9 3 45 32 4 53 67 4 75 

you can copy , past if like.

replace i++ j++ in for (int j = 1; j < numberofpeeps; i++)
