Basic input/output evaluation Write a C program that accepts the following input from the keyboard:

Student’s first name
Student's last name
Student ID number
Student's age

The program should then ask for the student’s marks as integers. It should use a loop to read the marks. The user should be allowed to enter up to 10 marks, or stop early by entering -1 (see the example below).

Your program should then use another loop to print the marks and calculate the average mark. If at least one mark is entered, the program should print the average mark to one decimal place

The program must validate all inputs. For example, each mark must be in the range 0 to 100. If an invalid input is entered, the program should print "Invalid input!" and prompt the user again.

An example of the output is shown below. Letters in bold red represent user input; the rest should be printed by your program.

What is your first name? John
What is your last name? Smith
What is your ID number? 00987654
What is your age? 23
Enter mark 1 (or -1 to terminate): 30
Enter mark 2 (or -1 to terminate): 67
Enter mark 3 (or -1 to terminate): 544
Invalid input!
Enter mark 3 (or -1 to terminate): 54
Enter mark 4 (or -1 to terminate): 34
Enter mark 5 (or -1 to terminate): -1
First name: John
Last name: Smith
ID: 00987654
Age: 23
Mark 1: 30
Mark 2: 67
Mark 3: 54
Mark 4: 34
Average: 46.3
