I can understand what you're say there because I'm human, even though it's not perfect English. Your C++ compiler, on the other hand, will crap out and die when confronted with anything that's not precisely C++. Compare you code with this:

#include <iostream>int main(){	std::cout << "enter two numbers:" << std::endl;	int v1, v2;	std::cin >> v1 >> v2;	std::cout << "the sum of" <<v1 << "and" << v2		  << "is" << v1 + v2 << std::endl;	return 0;}

I fixed your code, it would seem that you cant spell;

- you spelt ionstream instead of iostream
- you spelt std::count instead of std::cout
- at one point you dont even bother writing std::cout and just leave it at std::
- finally your formatting of code is rather bad but that might be just because you didnt use source tags (though this isnt an error to the compiler it makes it harder for people to read your code when not formatted correctly)

#include <iostream>int main(){	std::cout << "enter two numbers:" << std::endl;		int v1, v2;		std::cin >> v1 >> v2;	std::cout << "the sum of " << v1 << " and " << v2		  << " is " << v1 + v2 << std::endl;	return 0;}

also, can you please use source tags in the future
Thanks

Yeah to maintain the formatting in a post you have to wrap code in [ source ] [ /source ] or [ code ] [ /code ] tags (but without spaces within the square brackets). CodeCriminal and I both used source tags to get the white box with keyword colourising and automatic scrolling for when the code gets too big. Code tags won't do that, they just maintain the indents and use a monospace font.

I did not know the difference between source and code tags. Kudos to you.
