I'm new to programming, so I was wondering...

If I have an input file consisting of 100 lines, how do I read only up to line 50 and print out each line?

Thanks.

    Use a variable to keep track of many lines you've read and stop when it is equal to 50. – wally May 01 '16 at 02:25

    If you've tried and have a specific issue post an example of the issue and the code – Cameron637 May 01 '16 at 02:26
  • 1. Take and initialize a counter to zero (to count the number of lines you read) 2. Use a loop and continue it until the counter value is 50 3. Inside loop read a line from file and increment the counter by 1 – Monirul Islam Milon May 01 '16 at 14:41

Please use 'fstream' to read your file and count each 'readline'. Each 'readline' means a full line which terminated with '\n'(return value without it). That should be useful.

  1. create a fstream object fstream f("filename");

  2. Keep a counter, read lines from file till the counter less than 50 Something like this

      counter = 0;
  while((counter < 50) && (f.good())
  {
     getline(f,str);
     cout<<str<<endl;
     counter++
  }

    Note: this is not the full code, but guideline how to do.
