Write the defnition of the function int computeProd() with parameters that receives as arguments two integer values computes their produc and returns it to the celing function.

C++ Write a void function that has two parameters: a value parameter called num that receives a floating point number from the calling function and a floating point reference parameter called result. The functions should do this calculation: 25.0 * num + 37 and store the answer in result. Do not do any read or write operations in the function.

I need help with this in C++: Write a pair of functions countEven(int *, int) and countOdd(int *, int) which receive an integer array and its size, and returns the count of even or odd numbers in the array.

Write a function prototype and a function definition called average that receives an array of type integer, and the number of elements in the array.  It returns the average of the numbers in the array.
