This is my problem
//now use outfile of cout to write to the file;
// use "\t" to seprarte fields
for (int k = 0; k<= m-1 ; k++
outfile << pa [k] << "\t" << qa [k] << endl;
}
I need help in writing a solution to the above problem with the info provided. Whatever help or suggestions would help me to understand and then I can complete the rest of the program. This is an array type problem and there is much more than what I submitted. Thank you.

Here is the entire problem which is an inventory: sorting and updating using arrays also the Indat File or input file. I need to write a code to run this program, everything else is done with no errors or warnings. I hope this is enough info to help solve this problem, if this is not enough, let me know. Thanks

void swap(int &r, int &s);
