. if/else if Statements: Consider the following code

// This program prints "You Pass" if a student's average is

// 60 or higher and prints "You Fail" otherwise

// PLACE YOUR NAME HERE

#include

using namespace std;

int main()

{

float average; // holds the grade average

cout << "Input your average:" << endl;

cin >> average;

if (average > 60)

cout << "You Pass" << endl;

if (average < 60)

cout << "You Fail" << endl;

return 0;

}

Exercise 1: Run the program three times using 80, 55 and 60 for the average. What happens when you input 60 as the average? Modify the first if statement so that the program will also print You Pass if the average is greater than or equals 60.

Exercise 2: Modify the program so that it uses an if/else statement rather than two if statements.

Exercise 3: Modify the program from Exercise 2 to allow the following categories:

Invalid data (data above 100),

A category (90100),

B category (8089),

You Pass category (6079),

You Fail category (059).

What will happen to your program if you enter a negative value such as -12?
