fetching two numbers separated by a whitespace (noob question)

[johnmcmadeup@gmail.com]

How can I make it so that, if the user inputs 2 numbers with a space
in between , I can get both numbers(instead of just the first number,
which happens when I try cin>>var;)?

std::cin >var1 >var2;

Thanks a lot. I always though that that would force the user to hit
enter between the 2 numbers.

Any whitespace will do, space, tab, enter. In fact if it's a number any non
number will cause the first input to stop. This may cause the var2 to not
get a value if it's not a number. I.E. If the user enters
1x2
var2 is undefined.

Also, if you want all the numeric digits in one variable you could use a
std::string and getline. I.E.

std::string Line;
std::getline( std::cin, Line );

That will accept all characters types into Line until the user presses
enter. But then it's a string, not a number.
