4.3.7: Positive, Zero, or Negative - Codehs. Question/Test Case:
Write a program that asks the user for a number. Report whether that number is positive, zero, or negative.

Problem/Error:
File "main. py", line 5
if number < 0:
^
SyntaxError: invalid syntax

My code:
print("Enter a number to see if it's positive, negative, or zero!")

number = int(input("Enter a number: ")

if number < 0:
print(str(number) + "That number is negative!")
elif number > 0:
print(str(number) + "That number is positive!")
else number == 0:
print(str(number) + "That number is zero!")

Consider the following statements: struct nametype{string first; string last; }; struct coursetype{string name; int callnum; int credits; char grade; }; struct studenttype{nametype name; double gpa; coursetype course; }; studenttype student; studenttype classlist[100]; coursetype course; nametype name; mark the following statements as valid or invalid. if a statement is invalid, explain why.a.) student.course.callnum = "csc230"; b.) cin > > student.name; c.) classlist[0] = name; d.) classlist[1].gpa = 3.45; e.) name = classlist[15].name; f.) student.name = name; g.) cout < < classlist[10] < < endl; h.) for (int j = 0; j < 100; j++)classlist[j].name = name; i.) classlist.course.credits = 3; j.) course = studenttype.course;

The narrative structure of the popular movies can be broken down into

The volume v and paper surface area a of a conical paper cup are given by where r is the radius of the base of the cone and h is the height of the cone. a. by eliminating h, obtain the expression for a as a function of r and v. b. create a user-de ned function that accepts r as the only argument and computes a for a given value of v. declare v to be global within the function. c. for v ! 10 in.3 , use the function with the fminbnd function to compute the value of r that minimizes the area a. what is the corresponding value of the height h? investigate the sensitivity of the solution by plotting v versus r. how much can r vary about its optimal value before the area increases 10 percent above its minimum value?
