Modify the query select 'John Smith' from DUAL;. This time, use the SUBSTR function to extract a substring that represents your last name from the text string 'your_first_name your_last_name'. Assume you know the number of characters you need to extract.

Modify the query select 'John Smith' from DUAL; . This time, use the INSTR and SUBSTR functions to extract a substring that represents your first name from the text string 'your_first_name your_last_name'. Assume you do not know the number of characters to extract.

Modify the query select 'John Smith' from DUAL; . This time, use the INSTR, SUBSTR, and LENGTH functions to extract a substring that represents your last name from the text string 'your_first_name your_last_name'. Assume you do not know the number of characters you need to extract.

This program should be a short piece of code that prints all of the positive integers from 1 to 100 as described more fully below. the program may contain multiple methods, and if using an oo language, should be contained within a single class or object. the program should be designed so that it begins execution when invoked through whichever mechanism is most common for the implementation language. â–ş print out all positive integers from 1 to 100, inclusive and in order. â–ş print messages to standard output, matching the sample output below. â–ş in the output, state whether the each integer is 'odd' or 'even' in the output. â–ş if the number is divisible by three, instead of stating that the number is odd or even, state that the number is 'divisible by three'. â–ş if the number is divisible by both two and three, instead of saying that the number is odd, even or divisible by three; state that the number is 'divisible by two and three'. â–ş design the logic of the loop to be as efficient as possible, using the minimal number of operations to perform the required logic. sample output the number '1' is odd. the number '2' is even. the number '3' is divisible by three. the number '6' is divisible by two and three.

Write a program that asks the user to enter the name of an input file. if the file does not exist, the program should prompt the user to enter the file name again. if the user types quit in any uppercase/lowercase combinations, then the program should exit without any further output.
