Send Back Sum and Difference With Two Out-Parameters

Complete void sumAndDiff(int a, int b, int *sum, int *diff) so it stores a + b in the int that sum points at, and a - b in the int that diff points at. The difference is a - b, so it can be negative.

main is already written: it reads two integers, calls the function, and prints both results.

For the input:
8 4

Print exactly what is shown in Expected Output.

Expected Output:

Sum: 12↵
Difference: 4↵

= newline. The output ends with a newline — print one after the last line.
