Putting limits on values taken from a file

I am accessing a file in the following way

ifstream infile("Info.txt",ios::in);

while(infile>>freq>>dbels)
{
arr1[i]=freq; //of course all the variables are declared
arr2[i]=dbels;
i++
}

However, now I want to put a limit on either the freq or dbel value that I take in. i have tried

do
{
infile>>freq>>dbels;
..................
} while(freq<=2000);

However this is not working.

Any suggestions,

Thanks,

:confused:

pretty easy to fix this problem

just use:

if(freq<=2000)
infile>>freq>>dbels;

maby this is what you mean

other wise change the loop to:
while(freq<= 2000){
infile>>freq>>dbels;
}
