Please anyone, Am having problems reading all lines of my txt file.
below is the function i wrote to read the data in the file and search thru them. but it appears to read just only the first line.. please anyone.

int stop_tag(string f_name, string u_file,string file_put)
{
ofstream f_out;
f_out.open(file_put, ios::app);
f_out<<"Location of STOP condons TAG found at Locations :" <<endl;
ifstream yourfile (f_name);
size_t search;
if (yourfile.is_open())
{
while ( yourfile.good() )
{
getline (yourfile,u_file);
for ( int p = 1; p < u_file.length(); p++)
{

search = u_file.find("TAG");
if ( search!= string::npos)
{
cout <<search<<",";
f_out<<search<<",";
break;
