[mostakim hamza]

Hello Everyone
I know I can do this with c++ but I don't Know How !!!
anyway I will tell you maybe can someone help me :)

I have a file text date type string and I want search in this file for a sentence ( /santa-diabla/video/santa-diabla-ep-@/@@@@@@@@ )

Note: ( @/@@@@@@@@ ) is a variable

and after search I want copy all sentence in a new file text, there is 136 sentence .

( look at this photo for understand more what I want )

Use a regular expression: href\=\"(\/santa\-diabla\/video\/santa\-diabla\-ep\-\d+/\d+)\"
Search the file for that pattern and get group 1 from each match.

@helios

#include <fstream>
#include <string>
#include <iterator>
#include <iostream>

int main()
{
	const std::string tofind {R"(/santa-diabla/video/santa-diabla-ep)"};

	std::ifstream ifs("hj.txt");
	std::ofstream ofs("newhj.txt");

	if (!ifs || !ofs)
		return std::cout << "Cannot open files!\n", 1;

	const std::string data((std::istream_iterator<char>(ifs)), std::istream_iterator<char>());

	if (data.empty())
		return std::cout << "Error reading data\n", 2;

	int cnt = 0;

	for (size_t fnd = 0, fndq = 0; (fnd = data.find(tofind, fnd)) != std::string::npos; fnd = fndq) {
		fndq = data.find('"', fnd);
		ofs << data.substr(fnd, fndq - fnd) << '\n';
		++cnt;
	}

	std::cout << cnt << " instances found\n";
}

which displays that the required 136 file names have been found and extracted to the specified output file from the specified input file.

I only use MS VS - I don't know code::blocks. This compiles and runs OK with VS 2019.

Look at the first warning message - you need to use the specified compiler options.

just Maybe hhh it is 2 GB brother;


}if else ( "can you do it for me please ❤️ " = Yes ){

 cout << " Thank you So Much " << " + " << " you can download file 'hj' from here:  " << " https://1drv.ms/t/s!AqPOyLnFsNTObVX-eGh8FwmWWxY?e=7Bl9 " << endl;

}else ( " visual studio 2010 " != enough && "can you do it for me please ❤️ " != Yes ){

cout << " Thank You Very Very much Brother For All Thing did it for me " << endl;

You're compiling as c++98 with code::blocks. That version of C++ is ancient. To compile using the current standard requires some command line options to be used. The warning message suggests what to use. If you're going to be doing much C++ programming, you need to know how to compile using the current standard. As I said, I only use MS VS so can't really say how to with code::blocks

However, I've tried to 'strip out' the non-C++98 stuff from above. Try:

#include <fstream>
#include <string>
#include <iterator>
#include <iostream>

int main()
{
	const std::string tofind = "/santa-diabla/video/santa-diabla-ep";

	std::ifstream ifs("hj.txt");
	std::ofstream ofs("newhj.txt");

	if (!ifs || !ofs)
		return std::cout << "Cannot open files!\n", 1;

	const std::string data((std::istream_iterator<char>(ifs)), std::istream_iterator<char>());

	if (data.empty())
		return std::cout << "Error reading data\n", 2;

	int cnt = 0;

	for (size_t fnd = 0, fndq = 0; (fnd = data.find(tofind, fnd)) != std::string::npos; fnd = fndq) {
		fndq = data.find('"', fnd);
		ofs << data.substr(fnd, fndq - fnd) << '\n';
		++cnt;
	}

	std::cout << cnt << " instances found\n";
}
