Enter a number to search: 20 Occurrence(s) : 3
Machine Problem 5.4.
Write a program using two-‐dimensional arrays that determines the ODD numbers among the12 input values typed fromthe keyboard and prints the list of these ODD numbers.
Sample input/output dialogue:
Enter twelve numbers: 8 9 10 7 25 30 69 101 798 10111 10023
Odd numbers are: 9 7 25 69 101 10111 10023
Machine Problem 5.3.
Write a program using one-‐dimensional array that accept five input values from the keyboard. Then it should also accept a number to search. This number is to be searched if it is among the five input values. If it is found, display the message “Searched number is found!”, otherwise display “Search number is lost!”.

How many grams of FeCl3 are present in 15.00 mL of the solution? (Molar mass of FeCl3 = 162.2 g/mol)
Given the following market demand function for the commodity X Q=f(P,, P., P, I.T.A)
where
P= Price of the commodity X P= Price of a substitute commodity Y
P= Price of commodity Z which is complement of X
1 = Level of per captia income of consumers T=Tastes and preferences of consumers A = Advertising expenditure by a firm producing X
How will the market demand for a commodity change? (1) if price of the commodity X rises,
(ii) if price of the substitute good Y rises, (iii) if price of complementary commodity Z falls,
(iv) per capita income (I) of the consumers rises,
(v) the firm producing X increases its advertisement expenditure.
