Question

C++, C-Strings !

That's my problem: http://screencast.com/t/sBjt9Dzoq7RZ
That's my code: http://pastebin.com/TLXgMRJk

It asks for me to copy one string to another without using predefined functions apart from gets(). as strcpy() is a predefined function , I can't use this to solve my problem. Is there another way to copy one string to another ? Please help me. Thanks a lot for reading .

Answer 14

Well, their instructions contradict themselves.... if you were not able to use predefined functions how could you print? Hehe. But I think they mean for the copy. I'm looking at the code now.

Answer 15

yea most likely ;p

Answer 16

AH! Your loop!
```
for (i=0; S1[i]!='\0';i++){


}
```
Nothing in that.

Answer 18

In this loop I just want i++ so that I can say var = i

Answer 19

after the loop is over

Answer 20

OK. So you are using it to find the last position.

I would normally copy inside the loop that way.

Ok it's done.

Took the life out of me :p

Answer 23

Hehe.
The fun thing is, you could do it all in one loop. Copy and cout one right after the other, stopping when you hit the null.
