Re: Segmentation Fault in C++ Program – Need Debugging 1 Month Ago by rproffitt Thanks for the MVE (minimum viable example). But it's just bad code. c, c++ and a lot of language won't stop you from going out of bounds. Re: Segmentation Fault in C++ Program – Need Debugging 1 Month Ago by Dani You’re creating an array of 5 integers and then trying to access the 11th integer in the array (assuming the indexes start at 0). You’re getting an out of bounds error because you’re trying to access an array element that doesn’t exist. You can access arr[0] up through arr[4]. Re: Segmentation Fault in C++ Program – Need Debugging 1 Month Ago by Salem It should be obvious by now from their posting history that the OP is a troll. std::endl vs newline 10 Years Ago by Tycellent std::endl vs \n Are any particular one which should be used at specific times? I understand endl flushes the stream (although i'm not 100% what this means) while \n is simply a newline. Re: std::string question! 14 Years Ago by pseudorandom21 std::string is a C++ class (or maybe a typedef'd … access operator ([b] .

For your example, use the `.c_str()` function from the `string` class to get the `C-style` string. std::ofstream Myfile(mystring.c_str()); [Click Here](http://www.cplusplus.com/reference/string/string/c_str/) to get more info.

In my previous post I stated that you could also declare it globally with listings; using std::cin; using std::cout; this will also eliminate the need to type the prefix std:: Re: std:: 17 Years Ago by carnage i did read. what i'm asking exactly is when i declared globally: using std::cin; using std::cout; the one's i'm using in statements would be plain cin and cout only or still std::cout<< std::cin>> i was just reassuring ;) well i got my answer Re: std:: 17 Years Ago by Narue …include <iostream> int main() { using namespace std; cout<<"Hello, world!\n"; } …cplusplus] #include <iostream> int main() { using std::cout; cout<<"Hello, world!\n"; …=cplusplus] #include <iostream> int main() { std::cout<<"Hello, world!\n"; } [/… Re: std:: 17 Years Ago by carnage i was about to ask this question too so what's the proper way? i always do declare globally this one [code=c++]using namespace std;[/code] should i just declare this one globally instead (if i'm using it) using std::cin; using std::cout; Re: std:: 17 Years Ago by Narue >using namespace std; >is required for u 2 be able to use … No, it's not.

Re: std:: 17 Years Ago by plgriffith Unless you are at a professional level there are very few times where you shouldn't include using namespace std; ...unless of course you want to learn something.

Re: std:: 17 Years Ago by IIMarckus Thanks a lot guys. I'm still pretty new to C++, so this really helped me out. So the line [inlinecode]using namespace std;[/inlinecode] has nothing to do with using iostream over iostream.h? Guess that's another misconception cleared up. Re: std::endl vs newline 10 Years Ago by rubberman A newline in a string is just some more data to send, whereas std::endl will send a newline and then flush the output. You can also use std::flush to flush the output in those cases where you don't want a newline (input prompts for example).
