This is for C++, I was wondering if anyone could help me

Please use as a reference Programming Challenge #1 "Sum Of Numbers" of your textbook on page 297. You will need at least 4 functions: menu, summation, factorial, and exponential.

Make sure that your header block shows that you have functions and how information is passed between them. Each function should have its own header block. A header block is comprised of several lines of comments at the top of each function that explain what the function does. See program 6-28 in your chapter for examples.

Think about the scope of your variables. Variables used only inside of the function should be declared locally to that function. No global variables, please. Return "choice" from displayMenu function. And, (for example) if you have a counter variable down in Summation, then declare it locally to Summation.

Make the menu display and resultant output look very clean and professional.

Same validation requirements as what you submitted for previous assignments such as invalid selection etc.

Pseudocode for the main function might look like this:

main()

do

choice = displayMenu (this function will return the user's choice)

switch on choice

case 1

call function to handle summation

case 2

call function to handle factorial

case 3

call function to handle exponential

case 4

output goodbye statement

case 5

handle incorrect choice (ie, choice not 1-4)

end switch

while (choice not equal to 4)

end main

--------pseudocode for displaymenu function

int function displayMenu()

output the menu

input the user's choice

return choice

-------pseudocode for function summation

void function summation()

prompt for summation maxNumber

input maxNumber

while (maxNum <0 or maxnum> TOOBIG)

output error message

input maxNumber

end while

etc.....
