This challenge activity consists of a series of auto$-$generated, randomized questions allowing unlimited submissions. You must correctly answer a question at each level before proceeding to the next level. The purpose of this first level is to familiarize yourself with how the autograder works.

Click the "Start" button to begin the challenge activity.

Copy the code provided and paste the code into the code window. The following code uses cin $>>$ to read in a value for variable numPlums. Then, uses cout $<<$ to output the value of numPlums, followed by $"$:plums". Then, uses $<<$ endl to end with a newline.

cin $>>$ numPlums;

cout $<<$ numPlums $<<"$:plums" $<<$ endl;

Click the "Check" button to test your code. Our autograder automatically runs your program several times, testing different input values each time to ensure your program works for any values. An explanation is also provided.

Note: You can only edit lines where the line number $($shown on the left$)$ are white. Lines with grey line numbers cannot be edited.
