problems with ./a.exe

[Winer]

I've just started learning c++ and I am currently watching a youtube series on how to progress, I am having problems with g++ filename.cpp and ./a.exe when I use g++ it should save my newest line of code that I have inputted if I am correct, but when I go to test the code using ./a.exe I get the same line of code that has no changes at all. I will leave my code down below.


The response when I type ./a.exe is " You Have 10 slices of pizza.
10."

#include <iostream>

using std::cout;
using std::cin;

int main()
{
	int slices;
	cin >> slices; 
	cout << " You Have " << slices << " slices of pizza." << std::endl;

}

When you type "g++ filename.cpp", do any errors get spit out?

Btw, if you want an actual name for the exe, you could do something like
g++ filename.cpp -o filename

Also, turning on warnings (at least -Wall) can help find bugs before they happen.
g++ -Wall filename.cpp -o filename

Your current code does not compile,

 In function 'int main()':
8:2: error: 'cin' was not declared in this scope
8:2: note: suggested alternative:
In file included from 1:0:
/usr/include/c++/4.9/iostream:60:18: note:   'std::cin'
   extern istream cin;  /// Linked to standard input
                  ^

Use std::cin or add using std::cin;

When in doubt, delete the old executable and re-do the steps you're following.

when I do "g++ filename.cpp" I get no errors. I have added using std::cin;

I have also deleted the old executable and ran g++ filename.cpp and it creates a new executable but it still runs the old code for some reason. What I was told in the video it shouldn't run anything and it should be blank in the console when I do ./a.exe

Don't forget to press 'Save' in your editor as well.

Forgetting to save means recompiling the old program, and still getting the old results.
