C++ resources - you should use a C++ IDE to practice. - the playground is limited https://www.sololearn.com/discuss/459759/?ref=app IDE ------ code blocks https://www.sololearn.com/discuss/608805/?ref=app visual studio https://www.sololearn.com/discuss/410578/?ref=app

Also the numbers you got after 3, for output. That is from the error caused by using cin for a and b in one statement.

I left the instructions in the code for you. Read the comment and the prompt for input.

Multiple inputs on the same line using a single cin. Is not allow by the compiler.

if you want multiple inputs you should separate them with spaces Input: 3 12 will generate Output: 312 because you don't separate your output variables you should rewrite the output statement like this cout << a << " " << b; this will generate output: 3 12

a new question: is there an option in which i can input two variables at the same line? accordingly, i see that i can't add more the one insertion operator "<<" in cin, is that right?
