Accessing specific line from file in C++

Question

0.00/5 (No votes)

See more:

if there are 10 names (each line separated). How can I access any specific name on specific line.
I tried changing string to array but it prints single digit instead complete name.

What I have tried:

string f;
fstream file;
file.open("names.txt");
for (int i = 0; i < 10; i++)
{
    file>>f;
    cout<<f<<endl;
}

Content of names.txt

You have not shown the contents of your "names.txt" file. Also do not write a loop that way, as there may be more or less than ten items in the file. Use a test for end-of-stream to terminate the loop.

I have updated question with "names.txt" content.

Solution 1

You need to read the file one line at a time (to separate the names) and then select the specific line you need, probably by the line number which you can work out by keeping a count you update as you read each line.

You can do this with getline (string) - C++ Reference[^]

Solution 2

Try this:

C++

fstream file;
file.open("names.txt");
char line[64];
int lineno = 1;
do
{
    file.getline(line, 64);
    if (file.gcount() > 1 && !file.fail())
        cout << lineno << ". " << line << endl;
    lineno++;
} while(!file.eof());
