Question

list.txt

first 10
second third 20
fourth fifth 30

What’s the conventional way to read the first line separately from the others, such that I can use “first”,”second”, … and 10, 20, … as their respective types elsewhere in the program?

Thanks!

Is this what you’re thinking of?

ifstream fin("list.txt");

string str1, str2;
int n;

fin >> str1 >> n; // first 10

// do something with "first" and 10

while(fin >> str1 >> str2 >> n)
{
  // do something with str1, str2 and n
}
