How to display a string in many lines, each lines have a specified length

[thuyptt]

Hi you!!

I am programming a part of my application and I met a trouble in
display test.

I used fgets to read each line in a text file and display all lines on
the screen. But the size of the window are too small to display all the
line(208,320), So can I ask you how to divide split a string(a line in
file) into many lines and dis play them on the screen so that all the
characters of the string would be displayed fully.
I am looking forward to your support!!

Can you contact me via my email: th*****@dsp.com.vn

Sincerely and thanks,

Thanh Thuy

I assume you are using some kind of "console" window for your
application. A console usually wraps the text if it extends past the
end of the line.

However, you may get a substring of the length you want:

# include <string>
# include <iostream>

int main()
{
std::string s("a long long long line");
std::cout << s.substr(0, 10); // prints "a long lon"
}

And you can "pause" by adding a

std::cin.get();

whenever X lines are printed.
