Hi,
I'm writing a text editor program, but I need the enter key to go down a line instead of entering in data. Does anyone have any ideas? This is what I have:
#include <iostream.h>
#include <stdlib.h>
int main()
{
char mytext[256];
cin.getline(mytext, 255);
cout<<mytext<<endl;
}
Thanks
Since getline stops entering info into your array everytime a newline is inputted (based on default behaviour) you could place one manually everytime it returns. As you're using C-style strings you can strcat a '\n' each time.
Could you give me an example?
Thanks
#include <iostream>
#include <cstdlib>
using namespace std;
int main()
{
char mytext[256];
cin.getline(mytext, 255);
strcat(mytext,"\n");
cout<<mytext<<endl;
return 0;
}
also, you'll probably have to add
#include <cstring>
to the preprocessor stuff.
Okay this is what I have now:
#include <iostream.h>
#include <stdlib.h>
#include <string>
using namespace std;
int main()
{
char mytext[256];
cin.getline(mytext, 255);
strcat(mytext,"\n");
system("PAUSE");
return 0;
}
It still goes right to the system("PAUSE") and doesn't do a return.
Oh, I think I understand what you mean. You'll need a character to terminate input otherwise your wordprocessor will never end -
#include <iostream>
#include <cstdlib>
using namespace std;
int main()
{
char mytext[256];
// ! ends the word processor
cin.getline(mytext, 255,'!');
cout << mytext << endl;
return 0;
}
Bear in mind your documents are limited to 255 characters with no ability to edit lines that you've already entered.
Hey that works perfect!
Thanks
