// Directions: Practice #7-2: Grade Selector

// 1) Add 5 double constants for the following values: 90, 80, 70, 60 representing grade ranges.

// 2) Create a double variable and assign it a grade.

// 3) Create a string varible for the grade.

// 2) Create an if, elseif, elseif, elseif, else structure to determine the letter grade of the score.

//      a) Greater than or equal to 90, assign an A to the grade variable.

//      a) Greater than or equal to 80 and less than 90, assign an B to the grade variable.

//      a) Greater than or equal to 70 and less than 80, assign an C to the grade variable.

//      a) Greater than or equal to 60 and less than 70, assign an D to the grade variable.

//      ) Assign an F to the grade variable.

// 5) Output appropriate message to the screen.  "A score of 93 is an A."

// 7) Submit your dotnetfiddle link in Blackboard.
