Write a C++ program and flowchart to find first and last digit of a number

Write a C++ program and flowchart to count number of digits in a number

You can use a minus sign to make a negative number like -2. What happens for each of the following and why?

>>> 2++2

>>> 2--2

>>> 2+-2

>>> 2-+2

What happens if you have two values with no operator and a space in between them and why?

Define a function PrintValue() that takes two integer parameters and outputs the sum of all integers starting with the first and ending with the second parameter, followed by a newline. The function does not return any value.

Ex: If the input is 1 4, then the output is:

10

Note: Assume the first integer parameter is less than the second.

Complete function PrintPopcornTime(), with int parameter bagOunces, and void return type. If bagOunces is less than 2, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bagOunces followed by " seconds". End with a newline. Example output for ounces = 7: 

42 seconds

Define a function CalcPyramidVolume() with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. CalcPyramidVolume() calls the given CalcBaseArea() function in the calculation. 

Relevant geometry equations: 

Volume = base area x height x 1/3 

(Watch out for integer division). 

Define stubs for the functions called by the below main(). Each stub should print "FIXME: Finish FunctionName()" followed by a newline, and should return -1. Example output: 

FIXME: Finish GetUserNum()
FIXME: Finish GetUserNum()
FIXME: Finish ComputeAvg()
Avg: -1

Write a function so that the main() code below can be replaced by the simpler code that calls function MphAndMinutesToMiles(). Original main(): 

int main() {
   double milesPerHour;
   double minutesTraveled;
   double hoursTraveled;
   double milesTraveled;

   cin >> milesPerHour;
   cin >> minutesTraveled;

   hoursTraveled = minutesTraveled / 60.0;
   milesTraveled = hoursTraveled * milesPerHour;

   cout << "Miles: " << milesTraveled << endl;

   return 0;
}

Define a function PrintFeetInchShort(), with int parameters numFeet and numInches, that prints using ' and " shorthand. End with a newline. Remember that outputting 'endl' outputs a newline. Ex: PrintFeetInchShort(5, 8) prints: 

5' 8"

Hint: Use \" to print a double quote.
