build an array based on data from file matching criteria

[shaun.pille]

I am trying to get data from a tab delimited file(example of a few
lines below). I want to count the number of authentications per hour.
The first and fourth line is an example of a line I would want to
count, the middle two are examples of other lines in the file that I
want to ignore. The approach I am looking at is reading the first
section and using the hour field as the address in the array.

int count = 0;
If (string contains "Successfully")
AuthCount[HourValue] = count ++

So the data below would result in
AuthCount[14]=1
AuthCount[15]=1

Any suggestions on how to write this?

Use a std::map<unsigned int,unsigned int>.
