Question

Given the following snippet of code, answer the following two questions based on the code: typedef enum {Sun, Mon, Tue, Wed, Thu, Fri, Sat} days; days x = Mon, y = Sat; while (x != y) { x++; } y++; printf("x = %d, y = %d", x, y); 1. What value will be printed for variable x? [ Select ] . 2. What value will be printed for variable y? [ Select ]

Answer 1

The code snippet is a C program that uses an enum to define days of the week and increments two variables within a loop. The value of x will be 6 (Sat) and the value of y will be 7 after running the program.

Step-by-step explanation:

The code snippet provided is written in C and uses an enum named days to define a set of named integer constants representing the days of the week. The enumeration starts with Sun having the value 0 by default and increments by 1 for each subsequent day. Variables x and y are created it and initialized to Mon (value 1) and Sat (value 6), respectively.

The while loop in the code increments x until it equals y. Initially, x is 1 and y is 6. The loop will run incrementing x by 1 until it becomes 6, which means when x equals y (Sat), the loop stops and y is then incremented by 1.

By the end of the script, after the printf statement, the value of x printed will be 6 (Sat) and the value of y will be 7 (one more than Sat, although it is not mapped to any day in the enum, it's the value after Sat in this case).

Answer 2

1) The value of x will be 6.

2) The value of y will be 7.

Step-by-step explanation:

1) The value of x will be 6.

The enum values are labeled by default from 1. This means that Sun = 1, Mon = 2, Tue = 3 and so on.

So, x = Mon = 2 and y = Sat = 6

x increases up to y = 6 in the while loop.

and then y also increments by 1.

2)So the value of y = 7.

You will need actual printf("Sun") or printf("Mon") for printing the actual text for the enum.
