7. 16-bit Sum Product

Write a function named compute that calculates the sum and product of two 16-bit signed integers and returns both results using reference parameters.

Function Requirements:

• a and b
  • Passed by value
  • Type: int16_t
• sum and product
  • Passed by reference
  • Type: int32_t
• Behavior:
  • sum = a + b
  • product = a * b
  • Arithmetic must be performed using 32-bit widening to avoid overflow

In main():

1. Read two integers a and b from standard input
2. Call compute(a, b, sum, product)
3. Print sum and product separated by a single space

Example 

Input:

30000 2

Output:

30002 60000

Constraints:

• a and b are 16-bit signed integers
  • Range: -32768 to 32767
• sum and product are 32-bit signed integers
• The multiplication result will always fit within a 32-bit signed integer
• Results must be returned only via reference parameters
• Do not use:
  • Pointers
  • Global variables
  • Structs or classes
  • Dynamic memory
• Use fixed-width integer types (<cstdint>) to ensure portability
