I need to end my function once the user inputs CTRL-X or '/'. I don't know how to detect/check for a user input of CTRL-X. The task given to me states: 'When you edit the file, you will enter data line by line and when done, you will enter ‘/’ or CTRL + X to exit.'
I have written this code so far. I'm a beginner so pardon my code.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
string data;
int line_num=1;
ofstream editFile;
editFile.open("edit_test.txt");
while(data!="/"){ //some kind of condition ORed with the condition already present in while loop?
cout<<line_num<<"> "; //I want to display line numbers every time the user presses enter
getline(cin, data);
if(data!="/"){
editFile<<data<<endl;
line_num++;
}
}
editFile.close();
return 0;
}
CTRL+X is the same as character code 24 (since X is the 24th letter of the alphabet). Barring any system interference*, all you need to do is check to see if character code 24 is in the input.
CTRL+X doesn’t tend to have any special system actions attached to it, so you shouldn’t have any problem getting it as input.
