open text file with argument argv[1] command line

How can I replace ifstream infile("jobs.txt"); with argv[1] command line?

This is my main function :

int main()  {         int arrSize=0;      vector<Process> procs;      vector<Process> proc;  int element1, element2, element3;  char comma;  ifstream infile("jobs.txt");          if (!infile.is_open()) {      cerr << "Can't open file" << endl;  }  else {      while (infile >> element1 >> comma >> element2 >> comma >> element3)      {  Process proc{element1, element2, element3};  procs.push_back(proc);      }  }  arrSize=procs.size();  cout << procs.size() << endl;    int n = sizeof(proc) / sizeof(proc[0]);      findavgTime(procs.data(), static_cast<int>(procs.size()));  }
