You are tasked with creating a program in java to evaluate students' academic records and determine their eligibility for promotion to the next grade. The evaluation is based on three factors: exam scores, assignment scores, and attendance.

Requirements:

Students must have a valid exam score $($between $0$ and $100),$ a valid assignment score $($between $0$ and $50),$ and a valid attendance percentage $($between $0$ and $100).$

$2.$Students need to meet specific criteria for each grade level.

Grade Criteria:

A Grade:

Exam Score: $>=70$

Assignment Score: $>=30$

Attendance: $>=75\%$

B Grade:

Exam Score: $>=60$

Assignment Score: $>=25$

Attendance: $>=70\%$

C Grade:

Exam Score: $>=50$

Assignment Score: $>=20$

Attendance: $>=65\%$

Output:

If a student meets the criteria for a grade, print a message congratulating them on passing with that grade.

If a student does not meet the criteria for any grade, print a message indicating that they did not pass.

Execution Instructions:

$1.)$ Prompt the user to input the exam score, assignment score, and attendance percentage.

$2.)$ Check if each input is within the valid range.

$3.)$ Use nested if$-$then$-$else statements to evaluate whether the student meets the criteria for an A$,$ B$,$ or C grade.

$4.)$ Display the corresponding message based on the calculated grade or indicate that the student did not pass.

Note:

Ensure to include appropriate error messages for invalid input ranges and handle edge cases to provide clear feedback to the user.

This machine problem challenges students to design a program based on nested if$-$then$-$else logic to evaluate complex conditions for academic records.
