We have to make HTML form with 3 fields, all labeled appropriately:

Even or Odd: A text field for entering a number.

Grade: A text field for entering percentage grades from 0-100.

Month: A text field for entering a numeric month value from 1-12.

IN PHP :-

The script for the first field (Even or Odd) will tell us if the number is even or odd. (Hint: Use the modulus operator.)

The script for the second field (Grade) will use if/elseif/else statements to figure out what the grade will be using the following values: "A" for a grade of 90-100, "B" for 80-89, "C" for 70-79, "D" for 60-69 and "F" otherwise. So if someone entered an 87 in the field your script would output "Your grade is a B."

The script for the third field will output the name of the month for the number input. So if the user entered 1 you would output "The Month is January.",  if the user entered 2 you would output "The Month is February.", and so on. Use a switch/case statement to accomplish this.

This is the simplest way to calculate grades. A student’s grade is the sum of the points earned on all assignments divided by the sum of the points available...
