Help C++ question

prototype, definition, and call biggest is a function that receives three integer arguments and returns the largest value of the three values. For example, the largest value in the set {10, 10, 3} is 10. The function returns a single value and does not print to the screen. Answer the three questions below and clearly label your answers (1a. 1b. 1c.). Answer only the questions I ask, do not write a main program, otherwise the entire problem will be 0 credit..

Write a C++ statement that declares the prototype for the biggest function. (function prototype)

Write the C++ statements that define the biggest function. (function definition)

Write a C++ statement that calls the biggest function and stores the result in a local variable named bigNum. Assume the variables num1, num2, num3, and bigNum have been defined and initialized. (function call)
