..
4:
in this text file i need to print only the lines between 2: and 3:. How could this be done?
You need to actually read every line, but you can ignore the lines at a specific "index" by simply not printing them.
how can i do that? can u tel me the keywords for doing them?
Really? How is it that so many people these days are getting into projects without knowing the first thing about C++? Here, this program will read and print every line in a file:
#include <fstream>
#include <iostream>
#include <string>
using namespace std;
int main()
{
ifstream in("myfile.txt");
if (in)
{
string line;
while (getline(in, line))
{
cout << line << '\n';
}
}
}
I strongly recommend getting a book on C++ and reading it. Alternatively you can search Google for tutorials. This forum is best suited for helping with specific problems, not teaching you from scratch.
