4. Show the output produced by each of the following program fragments. Assume that i, j, and k are int variables. (a) i = 6; j = 3; k = 4; printf("%d", (i+10) % k / j); (b) i = 5; j = 6; k = 7; printf("%d", (i + 5) % (j + 2) / k); (c) i8; j = ++i = 3- 2; printf("%d %d", i, j); (d) i = 3; j = 3* i-- + 2; printf("%d %d", i, j); 5. Write a C program that formats product information entered by the user. The item code can be any number between 100 and 999, price is a dollar amount up to $9999.99 and date should be in mm/dd/yyy format. Save the program in a file named as display.c, and submit the file online as your solution to this question. A session with the program should look like this: Sample Input: Enter item code: 583 Enter price: 13.5 Enter purchase date (mm/dd/yyyy): 10/24/2010 Sample output: Code Price Purchase Date 583 $ 13.50 10/24/2010 Hints: Use tabs to line up the columns. Tab stops are assumed to be eight characters apart.
