using the getline() function

[louiecerv]

When you need to read data from an input file one line at a time, you can use the getline() function.

Here is a sample code that reads data from a file onto an array of characters:

Code: [Select]


char horoscope[12][256];
int line = 0;
char next;
while ( !fin.eof() && line < 12 )
{
          fin.getline(horoscope[line], 256, '\n');
line++;
}

If the line is over 256 characters long, the parsing will not go as expected.

A better solution would be to use std::string and use the std::getline function that loads the line into the string, to prevent any possible memory problems.

Good day!!

What if I will not use the getline() function is there any alternative codes for running a program??

Thanks!!!

you can define your own getline function using a loop and the get() function.  There is a sample in our textbook showing how this can be done.
