C++ Homework: Parallel Arrays from text file -

i have load 3 arrays text file homework , can't figure out why isn't working. text file like:

jean rousseau   1001 15.50 steve woolston 1002 1423.20 michele rousseau 1005 52.75 pete mcbride 1007 500.32 

it's name on 1 line, id number , balance due on next line separated space.

this function import data:

void inputfromfile(string filename, int sizes, string namesar[], int idsar[], float balancesar[]) { // variables int indexcount; ifstream infile;  // initialize indexcount = 0;  infile.open(filename.c_str());  while(infile && indexcount < sizes) {     getline(infile, namesar[indexcount]);     infile >> idsar[indexcount];     infile.ignore(1000, '\n');     infile >> balancesar[indexcount];     infile.ignore(1000, '\n');     indexcount++; }  infile.close(); } 

this gets added array when output items...

infile >> idsar[indexcount]; infile.ignore(1000, '\n'); 

you read first number line, ignore characters until end of line, including second number. try read next name if number, , since aren't doing error checking, goes wrong.

this ignore entirely unnecessary: there nothing ignore between first , second numbers >> skip on leading whitespace. second ignore is necessary, since have skip newline @ end of numbers line before using getline read next name line. may easier use getline read data file, parse numbers line using stringstream. mixing formatted extraction (>>) line-based extraction can difficult right.

after input operation, must check state of stream ensure error did not occur. simple example:

if (!(infile >> idsar[indexcount]) {     /* input failed; handle error appropriate */ } 

a stream has number of state flags , when extraction fails, fail flag set , must cleared before continue using stream.
