string ICYTP;

cout << "Enter where the line is located " << endl;
getline(cin, ICYTP);
ifstream In(ICYTP.c_str());
In >> ICYTP;
In.close();

when i output ICYTP it gives me my original text that i inputted into the console;
However, i want it to equal the line in the text file.
I have been confused for quite some time now and cant figure out my mistake.
Can anyone offer a quick fix for this line of code.?

It will work if you put the cout before the In.close, but I would just use a different variable all together for input.

eg.

CODE

string ICYTP;
string input;

cout << "Enter where the line is located " << endl;
getline(cin, ICYTP);
ifstream In(ICYTP.c_str());

In >> input;

In.close();

cout << input << endl;


P.S. Please wrap your program in code tags, it makes things easier for us smile.gif

getline in c++ uses a character array.. so you would need to do something along the lines of

CODE

char cReadIn[256]
string strReadInBuffer;

while(!inputFile.eof())
{
   getline(cReadIn,256);
   strReadInBuffer = cReadIn;
   cout << strReadInBuffer << endl;
}//end while
